The Best Rugged Waterproof Smartwatches of 2021

The smartwatches can still be considered a new breed of gadgets which, similarly to the smartphones, have evolved from the traditional wearable (that could have been mechanical or with a battery, and some were waterproof / water-resistant) to a device more suitable for this century. While I won’t deny the usefulness of all the integrated technologies (fitness trackers, heart-rate monitors, integration with the IoT, pairing with a smartphone and more), there are some shortcomings that still plague all the smart wearable devices: the battery life has gone from years of battery life (or indefinite for mechanical watches) to days and even hours. But that’s something that we must accept as there isn’t yet a solution available in sight (the TicWatch may be on to something).


The concept of a smart watch is not really new, as engineers have tried many times, for many years, to strap a mini-computer to your wrist, but, the breakthrough into the consumer market came shyly with the Pebble series and it went into the mainstream with the emergence of the Apple Watch, Samsung Gear and Motorola 360 (along with the implementation of the Android Wear as a general OS for non-iOS smartwatches – some other third-party operating systems have also been developed afterwards).

In 2021, smartwatches don’t really need an introduction and you don’t have to explain to anyone what they’re good for and, while there’s a fairly large number of devices available, the focus of this article will be for the most rugged smartwatches which will survive a more harsh environment and all the punishment that comes from practicing outdoor sports and activities. So, without further ado, let’s see which are the best waterproof smartwatches (which can withstand a beating) on the market right now.

UPDATE 06.06.2021: I have added the Samsung Galaxy Watch3 to the best rugged waterproof smart watches list.

1. Garmin Fenix 6



For a long time, the Garmin smartwatches have been regarded as among the best sports tracking rugged devices on the market and, a month ago (August 2019), Garmin has launched its new Fenix 6 series which comes with some major improvements over the Fenix 5 rugged smartwatches, making no compromises and it shows in the price tag. It’s true that the Garmin products have always been intimidating cost-wise, but the Fenix smartwatches do offer a premium build, solid tracking capabilities, lots of sensors and if you opt for the Sapphire variant, you get an all-round rugged device which you will not be afraid to take along on your outdoor adventures.

The latest Fenix 6 has kept everything that made last year’s Fenix 5 Plus a fantastic smartwatch, including a plethora of sensors (such as the HRM, GPS+GLONASS+GALILEO, sleep and stress tracking and contactless payment), the ability to track a large variety of sports and a rugged body, but it has made available more types of lens (including solar Power Glass) and there is an increased variety of materials for the case (there are also more sizes), but the most significant changes are in the battery life department (significantly improved GPS mode), as well as in the number of features directed towards a better sports tracking experience.


In terms of design, the Fenix 6 and the 5 Plus share a similar look, both featuring a relatively large main body made of fiber-reinforced polymer and with a metal cover, while the bezel is stainless steel (or titanium and the Fenix 6 offers an additional option: diamond-like carbon coated titanium). But, when put next to its predecessor, you will immediately notice that the inner (black) bezel is a lot thinner, allowing for more screen real-estate (the bezel gradations are also gone); the front screws are also better integrated with the look of the smartwatch and overall, the device feels more aesthetically pleasing.

The outer metallic bezel is elevated above the display and it provides a reliable barrier in case you hit the watch on a flat surface, otherwise, you would have to rely on the screen protection, which can be glass (Garmin has decided to use Gorilla Glass 3 instead of the domed chemically strengthened glass), sapphire (which handles scratches a lot better, but makes the device more expensive) or Power Glass solar lens (which has the role of charging the battery of the rugged smartwatch when there is a lot of sunlight – you should not use a screen protector since it can reduce the solar intensity and the lens are scratch-resistant).

Note: Be aware that only the Pro and Sapphire variants of the Garmin 6 support Music, Maps and WiFi, while the 6 and 6S versions are limited to only the Bluetooth connectivity and lack any WiFi capabilities.
I recently took a look at Casio WSD-F30 and it was a behemoth even when compared to the beefier Fenix 3 (which measured 2.0 x 2.0 x 0.6 inches), so the Fenix 6, while still quite large, it will look better on the wrist, being slightly smaller (the 47mm variant measures 1.85 x 1.85 x 0.57 inches, but the 51mm 6X is only a bit larger, measuring 2.0 x 2.0 x 0.58 inches). By default, the Fenix 6 comes with a silicone strap, which is both durable and comfortable and, if you don’t find it elegant, the fixing mechanism is easy to operate, allowing you to quickly change the straps (you can choose between silicone, leather, titanium and nylon).


Garmin has placed three buttons on the left side: Light – can be used to turn on the device, view the controls menu and turn the backlight on/off; Up-Menu – press to scroll up through the widget loop and menus or hold to view the menu; Down – press to scroll down through menus and the widget. There are also two buttons on the right side, one for Activity/Enter (upper arrow icon) – select an option from a menu or start/stop an activity and view the activity list – while the other is for the Back/Lap – press it to return to a previous window / record a lap, rest or transition during an activity or hold it to view the watch face from any screen.

In terms of sensors, the Garmin Fenix 6 doesn’t lack any important ones, being equipped with a Compass, an Accelerometer, a Thermometer (which can be a bit inaccurate because of the body temperature), a Gyroscope, a Barometric Altimeter, a built-in Elevate optical heart-rate sensor (the smartwatch can also be paired with ANT+ and Bluetooth HR sensors), GPS / GLONASS and Galileo Satellite Navigation (GNSS), as well as Pulse Oximeter with Acclimation which has the role of detecting the saturation of oxygen in your blood, therefore showing you how well your body is acclimating to higher altitudes. The heart-rate sensor is surprisingly accurate, but, this type of sensor is not really the best with high intensity training, so it is advisable to pair it with a chest strap for more accurate measurements (you may need to wait for a few minutes until you get accurate readings, though).

Garmin has done a good job waterproofing the Fenix 6 which is water resistant to 10 ATM, which means that it can be submerged under water down to more than 300 feet, but, unfortunately, it does not have any shock / temperature / humidity resistance rating (that does not mean that it won’t survive short falls or the occasional bumps and scratches that can happen while performing any outdoor activities).


On the front, the Fenix 6 features a 1.3-inch LCD Chroma display (the Pro and Sapphire version offer a larger 1.4-inch display), with a resolution of 260 x 260 pixels and a pixel density of 283 ppi (which is an improvement over what the 5X Plus had to offer). It’s worth noting that no smartwatch from the Fenix 6 series has a touch-screen display and the only way to operate your Garmin smartwatch is by using the buttons – I hoped that Garmin liked Apple’s approach, where the true, significant upgrade comes every two years, but it doesn’t seem like Garmin has any intention of using a touchscreen display anytime soon.

Still, some would argue that a touch-screen would drain the battery life faster and that an athlete may find it annoying to operate a touch-enabled display, but, while these points are reasonably valid, considering that this is a premium device, this omission can be a deal-breaker for some. The screen is always on, but, to come easier on the battery, it has a transflective layer which has the role of brightening the display while using it outside, but, indoors, the screen can look quite dim (you can manually activate the back-light). The low-resolution of the Garmin Fenix 5 Plus was one of its main weaknesses and, while Garmin has improved the display for the Fenix 6, it still can do better, especially since there are some great screens from Apple and Samsung (but that’s the sacrifice needed to be done to gain better battery life – similarly to how Pebble handled things).


Similarly to the Fenix 5 Plus, the Garmin Fenix 6 did not go the Android Wear route and it uses its own proprietary software. The UI offers the ability to track almost any outdoor activity, such as Trail Run, Run, Triathlon (gives you scores, it monitors your heart rate, it tells you if you’ve been improving your fitness level, it shows maps of the area you ran and so on), cycling, swimming (the smartwatch can’t record your heart rate while swimming; it can automatically record swim intervals and lengths), kayaking, skiing (detailed stats of your skiing course, including the time and speed it took you to finish it), climbing, stair stepper, cardio, golf (keeps scores, it gives you detailed hole information and other overall statistics) and a lot more.

Every data collected by the sensors can be accessed from the Garmin Connect app, which gives an user-friendly way of viewing summaries or detailed info about your activities (the data is collected via WiFi in the case of the Pro models or via the Garmin Connect Mobile app when you are connected to your phone – compatible with both iOS or Android OS). You can also create schedules for your workout (it can be as structured as you want), so you can more easily follow a plan.
Besides the larger amount of activities that are being tracked by Garmin, other novelty elements are the redesigned widgets (which make it easier to track activities), there are new map display themes, the switch from the MediaTek GPS chip to the better Sony GPS chip, there is now more storage available (32 or 64GB, so you can store a lot more songs and listen to them using Bluetooth headphones) and the manufacturer has made significant improvements on the battery life.


The battery life was one of the best features of the Garmin Fenix 5, because, if you disabled the GPS and the heart-rate monitor and used the device only as a watch, you could get up to 2 weeks on a single charge (with the GPS on, you would get up to 24 hours and if used in UltraTrac mode (it accesses the satellite once a minute), the battery would deplete in about 60 hours). The Garmin Fenix 6’s battery life is even better, offering up to 36 hours on the GPS mode, 72 hours in Max Battery GPS mode and up to 2 weeks on use in smartwatch mode (no GPS); additionally, there is the Expedition GPS Activity mode which can offer up to 28 days of battery life and the Battery Save Watch Mode for getting more than a month of battery life (up to 48 days).

2. Casio WSD-F30



As the name suggests, the Casio WSD-F30 is the third attempt from Casio to create a smartwatch which accomplishes the perfect balance between toughness and functionality, therefore being both suitable for outdoor sports and being able to offer a great user-experience (mostly, in terms of software).

While the first WSD-F10 was a rather unique smartwatch, retaining both the classical look and the toughness of the digital G-Shock series (along with new smart technologies), the direct predecessor of the WDS-F30, the Casio WSD-F20, didn’t bring that much to the table, although some key improvements have been made to render it a better device (such as a more appealing design, the implementation of a GPS and more). At first glance, the Casio WSD-F30 doesn’t seem to have made significant upgrades as well, but, on a closer look, you can see that the body of the smartwatch is now slimmer and smaller, the display is improved and it comes with all the new features of the latest Wear OS.


The Casio G-Shock watches were characteristically larger and thicker than the average watch and the WSD-F20 preferred to keep the same dimensions, therefore shocking its potential users when they came face to face with the 2.42 x 2.22 x 0.61 inches smartwatch. Fortunately, the WDS-F30 has suffered some reductions, now measuring 2.38 x 2.11 x 0.58 which, may not seem that much, but you’ll definitely feel the difference on your wrist (the reduced weight also helps a bit, as it has gone from the 3.24 ounces of the WSD-F20 to 2.93 ounces).

As you can see, it is significantly heavier and larger than the Apple Watch 4 (while not really adding more screen real estate), but the size of the Casio WSD-F03 is justified because it’s there to provide a superior protection, especially while practising outdoor sports or other similar types of activities.


I can see that Casio retained the design line of the previous generation, still featuring two sets of large plastic bezels, with the outer one reminding you that it is part of the ProTrek series and revealing the location of each button and sensors; the bezels are elevated and have the role of protecting the screen in case you accidentally hit it on a flat surface, otherwise, you’ll have to rely on the scratch-resistant screen glass. Unlike the WDS-F20, where the protruding bezels were exposing some screws which kept everything together, the WDS-F30 has removed them, so the smartwatch looks a bit more elegant and less industrial (don’t worry, it still kept the feeling that you’re dealing with a tough, rugged smartwatch).

The metallic buttons are conveniently placed on the right side (Tool, Power ad App), while on the left side, there’s the Charging Terminal (the cable is backwards compatible with the previous two Casio smartwatches) and the Pressure sensor. On the front, on the inner bezel, there’s a small Charge LED light and, towards the bottom, there’s a water-resistant microphone (up to five atmospheres), which is useful for taking advantage of the Google Assistant.


The whole smartwatch is waterproof, so it can be submerged underwater down to 164 feet (obviously, the touchscreen will not work while submerged and I would suggest against wearing it in high humidity / high temperature environments) and it is MIL-STD-810G rated, therefore, similarly to the WDS-F20 it survived the transit drop and general vibration tests, it can withstand a moderate level of humidity, solar radiation and it should also be resistant to multi-cycle shocks from constant extreme temperatures or icing/freezing rain (and more).

Furthermore, the back of the smartwatch is a simple brushed metal fixed with visible screws and, while I have no complaints about the longevity of the plastic strap, it does feel quite rigid and I had a hard time detaching it (so, it’s not easy to swap between different straps – besides adding more holes to the strap, the rigidity is an element that hasn’t really been improved from the previous model). In terms of sensors, the Casio WSD-F30 is equipped with a magnetic sensor for direction, a pressure sensor, an accelerometer, a gyrometer and a low-powered GPS (it also is compatible with GLONASS and Michibiki) – unfortunately, Casio decided against adding a Heart rate sensor, which is inexplicable, since you can find it on less costlier smartwatches.


You can use the aforementioned Tool button to swap between the info given by each sensor, which includes a tide graph (useful for fishing, but not recommended for navigation purposes – use the official charts for that), the compass measurements, sunrise and sunset, the altitude, a coloured map of your location, an activity graph and more.

On the front, the main attraction is the 1.2-inch OLED display with a resolution of 390 x 390 pixels and a pixel density of 459 ppi (while the display is smaller, it is a lot better than what the WSD-F20 had to offer). Furthermore, there are actually two displays, with the OLED one positioned underneath a semi-transparent low-power monochrome LCD display that becomes active during the Multi Timepiece mode (which besides simply displays the time, it also offers additional sensor info – a useful feature for people that dislike having the display turned off most of the time, but taking on the battery life – in this mode, the smartwatch can go up to a month on a single charge).
Overall, WSD-F30’s display is greatly improved, but it’s still not really the best I’ve seen on a smartwatch, lacking a bit in terms of brightness (something really annoying especially while travelling), but it was reasonably vibrant and colourful.


The WSD-F30 uses the Android Wear 2.10 OS and some of the main applications are the Activity app (useful for tracking the current progress of your usual activities, such as fishing, trekking, cycling, paddling or snow activities), the Casio Watch Faces (choose between Location, Traveller, (updated) 2 Layers, Authentic, World Time, Place, Journey, Multi or Frontier), the ViewRanger App (great for mountain-climbing or trekking), BikeMap, Equilab, MyRadar, Location Memory and more.

Pairing the smartwatch to an Android phone is done really fast and it opens up a whole new set of features (such as answering a call, getting notifications, listening to locally stored music and more). The WSD-F30 will pair with an iPhone, but the features are a lot more limited.
Note: Inside the case, the smartwatch is equipped with a Snapdragon 2100 processor, 512 MB LPDDR3 SDRAM and 4 GB internal storage (it also equipped with the low-energy Bluetooth V4.1 tech and the WiFi 802.11 b/g/n).

The one major weakness of the Casio WSD-F10 was the battery life, which would barely reach a day with very light use. Unfortunately, the Casio made no real progress with the WSD-F20 and while the WSD-F30 also made no significant advancements, it does come with some battery saving modes which could push the battery life from 3 days (the Extended Mode) up to 1 month. One complaint that I had about the WSD-F30 is the charge magnet, which was very weak and difficult to be kept attached to the smartwatch and, to improve things on the Casio WSD-F30, you can add a clip to keep things tighter.

3. Samsung Galaxy Watch 3



The Samsung and Apple rivalry has transcended the smartphone market and it entered the smartwatch realm where each manufacturer tried to create the perfect smartwatch suitable for a broader audience. But, while the Apple Watch has effortlessly managed to capture the attention of the public (it almost single handedly put the smartwatch in the mainstream), the other smartwatches (mainly from the Android environment) still have a harder time becoming more relevant in the wearable market. This has also been the case for the Gear series for a while, with Samsung constantly trying to reinvent itself and give its smartwatch line a proper direction. The original Galaxy Watch was already proof that Samsung has gotten more serious and the latest Galaxy Watch seems to be even more refined which made the manufacturer confident that it can surpass Apple Watch’s reign.

While I doubt that’s going to be the case anytime soon, I do have to admit that the Samsung Galaxy Watch 3 is one of the better looking smartwatches on the market, sporting a design very close to the traditional watch, so it will go very well with a formal attire. Of course, some rugged elements are still present (otherwise it wouldn’t have been a part of the best rugged smartwatches list), so it will be suitable for outdoor activities and survive a slightly more harsh working environment. To accomplish this, it has kept the analogue-type watch look and surrounding the display, there’s the watch bezel made of stainless steel which rotates and gives easy access to your data.


Yes, Samsung has brought back the rotating bezel which got skipped with the Galaxy Watch 2 and it’s worth pointing out that the mechanism is even smoother than on the original smartwatch and will give a satisfying feeling while rotating it. But that’s not all because the stainless steel 316L case of the smartwatch is thinner and it has also lost a bit of weight, so it will feel better on your wrist. As before, the rotating bezel sits a bit more elevated from the screen, which gives the watch an increased protection against accidental hits. I would still be careful to not hit the device against sharp objects because the screen is not made of sapphire, but it is protected by Gorilla Glass DX – the same as on the previous two models. Besides the rotating bezel, the Galaxy Watch also has a Back key located on the right side of the smartwatch and, underneath it, there’s a Home/Power button.

Similarly to its predecessors and other smartwatch brands, the Samsung Galaxy Watch 3 is available as two models, one for smaller wrists (41mm) and the other for people with larger wrists (45mm). The 42mm Galaxy Watch seems to be aimed at women considering that it has a ‘larger’ palette of colors available – it includes Rose Gold.
The 45mm variant may initially seem a bit too large or too heavy when compared to the Apple Watch, but, let’s not forget that the Galaxy Watch is an outdoor-type rugged smartwatch and, when compared to the likes of Garmin Fenix 6 or Casio WSD-F30, this rugged smart watch is actually quite average. As expected, the Galaxy Watch 3 is equipped with all the important sensors: an Ambient Light sensor (to properly adjust the display brightness and contrast), A-GPS/Glonass/Beidou/Galileo, a Heart Rate sensor (positioned on the rear side of the smartwatch, where the device touches your wrist), an Accelerometer, a Barometer, a Gyroscope and an Electrical Heart Sensor (ECG).


Samsung still decided to not add a Magnetometer, so no Compass and there’s no Thermometer. At first, the heart rate monitor did not really seem that accurate while jogging, but, I noticed that after I tightened the strap on my wrist, it has greatly improved the accuracy of the readings.
One department that Samsung has made some improvements when it moved to the Galaxy Watch series was on the waterproof department so, similarly to the first model, the Galaxy Watch 3 can be submerged down to 165 feet (5 ATM). Furthermore, besides being waterproof, the Galaxy Watch is also dust-proof (IP68 certified) and it is MIL-STD-810G rated: it has survived 10 specific conditions, which includes low pressure, high altitude, drops from 4.9 feet, vibration and shock and extreme temperatures. Just like its predecessors, the Galaxy Watch comes with either a 20mm or a 22mm strap and it’s made of seemingly genuine leather. Both variants (42 and 45mm) allow the user to change the straps and the mechanism is easy to operate, so swapping them is quick and painless.

On the front, Samsung has equipped the Galaxy Watch with a 1.4-inch Super AMOLED capacitive touch-screen display , but the smaller version comes with a 1.2-inch screen. Both displays feature 16 million colors, have a resolution of 360 x 360 pixels and a pixel density went up to 364 ppi. Although no improvements have been made over the last generation, the display is still very much up to the 2021 standards: it is vibrant, the contrast levels are good, it’s bright enough for sunny days and the blacks are very deep (as expected from an AMOLED). Additionally to the rotating bezel, the touchscreen feels appropriately reactive and fast. The Galaxy Watch 3 allows you to set the display to be always on and, when you’re not looking at the screen, the display slightly dims and it supports a wider range of customization. This feature had a heavy impact on the battery life, so, if the battery life is extremely important to you, you can set the display to turn on only when you raise your wrist (the process is very fast and you won’t notice that the display is off).


Unsurprisingly, Samsung steered clear of the Android Wear and it remained with the proprietary Tizen OS which is now on version 5.5 (a way of competing with both Google and Apple). To navigate the interface, you can use swipe gestures (swipe left to see the notifications, the recently opened apps, view the weather and so on; swipe down to open the status bar, adjust the brightness and volume, open the music player) or the bottom right button (to open the app menu with its circularly arranged icons). If you press and hold the top right button, it will launch the Samsung Pay, which allows the smartwatch to be used as a credit card (supports both NFC and MST – therefore supported by almost all checkout terminals). The Samsung Pay feature will work with some non-Samsung smartphones (minus iPhones) and it can be used with the Galaxy Watch as a standalone (if you don’t have your smartphone with you).

Samsung has worked very hard to push the Tizen OS forward and gather the necessary attention from software developers, so there are far more apps available at the moment than with the first Galaxy Watch, but it seems that the next Galaxy Watch will use the new Google software. In any case, using Tizen OS, you get the Samsung Health (it provides fitness tracking, including new exercise modes for both indoors and outdoors workouts and can accurately enough detect when the user switches the exercise; it can also track your sleeping time decently well), Bixby (a voice assistant – useful to perform calls or send emails) or the SOS function (tap the Home key three times to send an emergency message to your contacts or perform an SOS call). The Galaxy Watch 3 will work with both Android smartphones (offers a full range of control, but you need to install the Galaxy Wearable app) and iPhones (also offers a wide range of control, but it is mostly limited by the iOS).

The Galaxy Watch is equipped with the same dual-core 1.15 GHz Exynos 9110 chipset as the first Galaxy Watch, it has 8GB of internal storage and apparently only 1 GB RAM. It’s a bit surprising that Samsung would cut the amount of RAM on the Galaxy Watch 3, even though so far, it didn’t seem to have had much of an impact on the performance of the device. Connectivity-wise, the rugged smartwatch supports WiFi 802.11 b/g/n and Bluetooth 5.0. Furthermore, the Galaxy Watch is also equipped with a non-removable 340-mAh battery, same as its predecessor. It’s clearly not enough to get an excellent battery life and the most you’ll be able to get with an LTE connection and with the always-on screen turned off will be about 2 to 3 days (with moderate use).

4. TicWatch Pro 2020

Read the full review



The original TicWatch Pro was built as a means to breathe some life back into the Wear OS ecosystem and for a 2018 rugged smartwatch, it had a tough exterior, while also keeping a premium look, the dual-layer display was and still is an interesting way to deliver more battery life, so all the basics were covered and some more, but it was missing a bit in the performance department. For a mid-range smartwatch, the 512MB of RAM were the norm, but two years later, you’re going to notice its slightly sluggish UI a lot more. To fix it, Mobvoi decided to release the TicWatch Pro 2020 which is the refreshed version of the aforementioned two year old smartwatch and it now has double the RAM, while also adding the MIL-STD-8190G certification, therefore making it a far more rugged smartwatch than its predecessor.

Design-wise, The TicWatch Pro 2020 is identical to the 2018 model, so expect the same graphite body with a metallic panel where it touches the hand, while the top bezel is still covered by numbers all around the screen. On the right side, there are two buttons and in between them, there is a microphone opening (for calls). Despite being a bit on the large side (it measures 1.77 x 0.49 inches – which is similar to the Nixon Mission SS), the Pro 2020 is still a lot more lightweight than its more expensive competitors and this is an aspect that some of you may appreciate (not many like a heavy watch on their wrist, especially when your wrists are thin since the watch will move downwards most of the time). The smartwatch that I tested is all black, but there is also a silver version and the straps are made of a combination between leather and silicone (the former sits at the top, while the latter on the underside).


Some TicWatch smartwatches had proprietary straps (because the manufacturer added a GPS antenna within them), but just like the original Pro, the 2020 version is more forgiving, so you can freely use any standard 22mm straps. The Galaxy Watch has a rotating bezel, while other smartwatches rely on a combination between the crown and the touchscreen display – the TicWatch Pro decided to use two buttons and the touchscreen, allowing the user to power on or off the smartwatch using the top button (requires a long press), to activate the Google Assistant (a long press while the smartwatch is active) or to enter the app menu (requires a single quick click on the button). The other button can be customized, but, by default, it will open the Mobvoi fitness suite. The rear side of the smartwatch has a dynamic optical heart rate sensor (which is decently accurate), while a bit to the left, there are four contact points for the charging cable (which attaches magnetically to the device).

On the front, the round bezel that surrounds the display is slightly raised to offer some level of protection in case you accidentally hit the smartwatch; there is also the Corning Gorilla Glass 3 protection which should help with scratches. But that’s not all the TicWatch Pro 2020 has to offer in terms of protection: the device is also MIL-STD-810G rated and, as Mobvoi has stated, the device was tested for sand, dust, shocks, humidity, extreme temperatures and pressure, and it survived. Furthermore, the TicWatch Pro 2020 is IP68-rated which means that it’s both dust and waterproof, and you should be able to go under 5 feet of fresh water without suffering any damage. In terms of sensors, the rugged smartwatch features an accelerometer, a heart rate sensor, a gyroscope, a geomagnetic sensor, an ambient light sensor, GPS, GLONASS, Galileo, Beidou and there’s also NFC for payments only with the watch; if you’re wondering about the connectivity, the TicWatch Pro 2020 supports 802.11 b/g/n WiFi standard and the Bluetooth 4.2 LE.


On the front, there’s a 1.39-inch AMOLED display with a resolution of 400 x 400 pixels (the same as on the original TicWatch Pro) and it’s actually more than decent (on par with other more expensive solutions), featuring vibrant colors and good brightness levels to ensure that the smartwatch’s display will remain visible in all scenarios. But a very important element is the secondary monochrome LCD display that sits on top of the AMOLED layer and it activates when you’re no longer using the smartwatch – this way, you get an always-on display while sacrificing almost nothing in terms of battery life. You still do get the traditional always-on mode (with a lower brightness), so the device can look like a regular watch (but it will have a heavy impact on the battery life). The TicWatch Pro 2020 will wake when you tilt your wrist and I did find the process a bit faster than on the TicWatch S and S2.

The TicWatch Pro 2020 uses the Wear OS (which will work with both iOS and Android smartphones) which is not really that loved by the community due to the development lag when compared to the Tizen OS or watchOS and also because the chip inside the smartwatches is not the most powerful (the TicWatch Pro 2020 is equipped with the Snapdragon Wear 2100 – the newer Wear 3100 is almost the same as its predecessor).


Still, Mobvoi does a decent job at delivering a balanced experience, offering some actually cool watch faces and, besides the default Android experience, the manufacturer has also added some proprietary apps such as the TicHealth, TicPulse and the TicExercise. The TicHealth is a replacement to the Google Fit and it counts your step and tracks your exercise, while the TicPulse has the role of monitoring your heart rate for 24 hours and the TicExrecise tries to detect the type of physical activity that you’re undergoing, so you don’t have to manually switch between the activity type.

Overall, the interface is reactive and reasonably quick, which is a great feat considering that it is equipped with the dual-core Snapdragon 2100 – it’s clear that the 1GB of RAM did have a significant effect on the performance of the smartwatch. The TicWatch S2 has a 415 mAh battery (same as the TicWatch S2) which can deliver up to 5 days if you switch between the Essential mode (only the LCD screen) and regular mode and, if you decide to keep the Essential mode for a longer period of time, it can go up to 30 days of a single charge. Furthermore, using the charging cable, it will charge the battery from 0 to 100 % in about one hour and a half. So, is the TicWatches Pro 2020 the next Pebble? What I loved about the Pebble smartwatch was the battery life, but also that it could deliver some smartwatch functions at the same time, so in this sense, Mobvoi hasn’t really filled that Pebble shaped hole in our hearts, but it has managed to design a decent rugged smartwatch which offers some sport-focused elements (similarly to the other waterproof rugged smartwatches), all that at a lower price tag than some of its competitors.

5. Nixon Mission SS



The original Nixon Mission wasn’t really the most attractive smart watch available, but it was more than suitable for outdoor activities, sporting a rugged case (with a combination between polycarbonate plastic and 316L steel – along with a corrosion-resistant coating), silicone straps and it used the Android Wear OS to give its users the full smart watch experience. A year after the first Mission smartwatch, Nixon released a new version called the Mission SS which comes with a far improved design, featuring a better rugged case (the front-facing bezel is now made of stainless steel – that’s what the SS from the name of the device means) and the silicone straps have also been replaced by 23 mm stainless steel bracelets, while it has kept all the other elements that made the original Mission a popular smart watch, including the magnetic charger and the cool braided cord.

If it wasn’t for the new metallic bracelets, it would have been hard to actually point the differences between the Nixon Mission SS and the original Mission smartwatch simply because besides the new stainless steel bezel, nothing has really changed: you still get that large case which only rivals the Garmin Fenix 5 in terms of size (the smartwatch measures 1.9 x 2.0 x 0.6 inches) and it also quite heavy (at its 3.56 oz) – although it is reasonably balanced on wrist, you won’t ever forget that you’re wearing it.


The metallic bezel does not rotate (like in the case of the Samsung Gear S3), but it does rise up enough to provide a protective lip around the display so, in case you accidentally bump the device into objects, there is a very low chance that you’ll be able to crack the screen (which, let’s not forget that it’s protected by Corning Gorilla Glass, so it will do fine with the usual scratches).

On the left side of the case, there’s a fairly large button (made of polycarbonate) with the Nixon name engraved on it (the display is touchscreen, so the button has minimal functions: while roaming the user interface, it will act as a Home button and it will also turn on the display or put the smartwatch back into the low-power mode) and on the right side, Nixon has kept the MicLock system which ensures the water resistance of the watch. Since this device is marketed as being suitable for surfers, it needed some serious protection and that’s where the MicLock offers the solution by covering the microphone with a small metal part (you need to slide it off the small lever), therefore the smart watch can pride itself with a 10 ATM water-protection.


Sure, the Mission SS is a waterproof and the 10 ATM suggests that you could submerge underwater down to 300 feet, but, in truth, while surfing, you could subject the smart watch to a pressure up to 3 ATM, so I wouldn’t really trade it for a professional device that can withstand deep dives.

That being said, the Nixon Mission SS is one of the toughest smartwatches available right now, being IP68 rated, so, besides the water proofing, it is also dust-resistant and the reason why this watch is so thick is to make sure that it will survive any type of outdoor activity (the Mission SS is marketed as a sports watch after all). In terms of sensors, the Nixon Mission SS comes with a Barometer, a Digital Compass, a Gyroscope, a built-in standalone GPS (it’s a great addition because you can’t always rely on the connection to your smartphone, so you can still accurately track your outdoor exercises using the native GPS – surfers will greatly appreciate this feature because it’s unlikely they’ll carry their phones with them in the water), an Altimeter, an Accelerometer, a Humidity sensor, an Ambient Light sensor and a Thermometer (which similarly to the Garmin fenix 5, can be a bit inaccurate because of the body temperature) – unfortunately, Nixon decided not to include a Heart rate monitor (which is a shame considering the price tag of the smart watch).


On the front, Nixon has kept the decently-sized 1.39-inch AMOLED display with the same 400 x 400 pixel resolution and the 406 ppi are still more than enough for a smartwatch screen which means that the Mission and the Mission SS have one of the sharpest display on a smart watch. Furthermore, the manufacturer decided to steer clear the flat tyre look and the screen is actually full 360 degrees, well, almost, because there still is a very subtle black band, but it is cleverly positioned making it virtually unnoticeable.

By default, the display is bright enough when you’re indoors, but it will be less clear in bright sunny days and, to counteract this, you could either manually rise the brightness level (which will have a heavy impact on the battery life) or enable the auto-brightness feature. Because the battery is still the number one problem with most smart wearable devices, the Nixon Mission SS’s display will turn off when you’re not looking at it to help preserve the battery life, but you can enable the Always On Screen feature, so it will look like any other regular watch.


The Nixon Mission SS uses the Android Wear OS (upgradeable to the newer Android Wear 2.0), so it will be easily paired with an Android phone (it will also work with iOS devices, but the features are more limited) and, while the default environment offers a complete smartwatch experience (watch faces, notifications, music player, take calls and more), Nixon has added some useful apps to help skiers and surfers called Trace Snow and Trace Surf. These apps will track the travelled distance, the max speed and the altitude – sure, they’re not overly complicated, but they do their job properly especially because of the (aforementioned) built-in GPS – you can also use an external sensor that can be attached to either your surfboard or snowboard in order to get even more data to your apps.

While using the interface there was no moment when I felt any stuttering or slow-downs and that’s because of the fairly potent internal hardware that Nixon has added to the Mission SS smart watch: it features a Qualcomm Snapdragon Wear 2100 SoC along with 4 GB of storage memory and 512 MB of RAM memory (which did raise some concerns at first, but it turned out that it was enough to handle every app that I wanted to run on the smart watch). Furthermore, in terms of connectivity, the Mission SS supports the WiFi 802.11 b/g/n standard, as well as the Bluetooth 4.1 technology (Bluetooth Low Energy).
The battery life is not really the best feature of the Nixon since the 400mAh built-in battery will manage to deliver up to 2 days if you don’t enable the built-in GPS and if you do use it, then you won’t see more than 6 hours of battery life. In order to charge the Nixon Mission SS, you have to use the magnetic charger which has a strong magnet (so it attaches firmly to the back of the smart watch).

6. Polar M600



Polar is one of the most popular manufacturers of running watches, its influence spanning back to as early as 1980, when it filed a patent for a wireless heart rate measurement feature, something that became a reality two years later in the form of the Sport Tester PE 2000. The Finnish company maintained its influence over the years and it has slowly evolved past the running tracker-only wearable to a more full-fledged smartwatch, first, with the release of the the M400 and secondly, with the latest instalment, the Polar M600, where the manufacturer further improved the formula by combining the fitness side of the watch (including the waterproof aspect) and the Android Wear experience in a harmonious manner.

Although it has completely entered the realm of smartwatches, the Polar M600 has kept the same familiar rectangular design (common for fitness trackers), instead of giving in an adopting a more elegant, circular body. But, while, I definitely appreciate the ‘unique’ factor that Polar may be trying to pull, the design of the M600 is completely uninspired and it may be one of its gravest shortcomings (I don’t really expect a fitness-focused rugged smartwatch to look stylish and elegant, but Polar could have tried a bit more when designing the M600).


So, we’re dealing with a fairly large rectangular case (it measures 1.77 x 1.41 x 0.51 inches) featuring a simple flat touchscreen, having the metallic lateral sides exposed, while the top and the bottom parts being slightly covered by the silicone strap.

Underneath the display, there’s a small button positioned on the strap, which has the role of opening Training in the main menu and choosing the sport you want to start and initiate the Training session, as well as stopping the session and quickly accessing the Polar app. Towards the left side, but, still protruding from the strap, there’s a Power button which, besides turning off and on the rugged smartwatch, it can also wake up the screen, adjust the dimming of the display, return to the home screen, open the apps menu (press it until the device vibrates), temporarily boost the brightness (press it three times) or turn the theatre mode on (press it twice). Even if the design is minimal and the smartwatch is fairly big, because of the silicone band, the Polar M600 is surprisingly comfortable to wear (it’s also lightweight and suitable even for long workout sessions).


The bands are also interchangeable, so, if you get bored by wearing the same colour every day, you can easily swap it for a new colour (they’re also quite inexpensive). Although not the most attractive choice, the silicone band is the most rugged element of the smartwatch, since it is slightly elevated over the display, therefore providing a certain level of protection in case you drop it face first and it will also absorb any other physical shock.

In terms of sensors, the Polar M600 comes equipped with an accelerometer, a gyroscope, an ambient light sensor, a vibration motor, a microphone, GPS (distance ±2 %, speed ±2 km/h accuracy) and a better optical heart rate sensor with 6 LEDs. The heart rate readings were surprisingly accurate and, to get the best results, it is advisable to make sure that the sensor rests about one inch above your wrist (not directly on it). The Polar M600 will also work with a heart rate chest strap, which will usually provide the most accurate results. Furthermore, the smartwatch is waterproof, which means that it is suitable for swimming down to 32 feet, being IPX8 rated (it’s not suitable for snorkelling, diving or fast water sports), it will remain functional if the temperature is between 14 degrees F to 122 degrees F, but it lacks any rating which would suggest protection against dust.


On the front side, Polar has equipped the M600 with a 1.3-inch transmissive TFT display, with a resolution of 240 x 240 pixels, a pixel density of 260ppi and it is protected by Gorilla Glass 3, which will provide protection against scratches (it won’t keep the display safe against heavy shocks, but, since we’re dealing with a relatively small display, it should be safe in most situations). I expected a bigger display when I first took the M600 in my hand, but it seems that the bezels trick you into thinking that the screen is larger than it actually is.

Nonetheless, the display is very responsive, but it lacks a bit in terms of quality: the colours aren’t vibrant enough (not even close to the Samsung AMOLEDs) and you can actually see the scan lines. On the bright side, the display was visible outdoors under direct sunlight, so you won’t be inconvenienced during your outdoors adventures. One interesting feature that the Polar M600 has implemented to save some battery life is the automatic turning-off of the display when you’re not watching it and, if you move the wrist to see the screen, the display turns on (it may take up to 2 seconds for this to happen, though).


The Polar M600 will work with both Android and iOS and the main centrepiece feature that has the potential of outclassing all the other fitness-focused smartwatches from the competition is the Polar Flow app (which will work on both platforms). The Polar app has the role of monitoring and tracking almost every aspect of your active life (including your sleep time, if you wear the M600 during the night) and it displays detailed analysis of your heart rate, speed and distance, the number of steps, the burnt calories and more.

Some of the key elements of the Polar Flow app are the instant visual representation of the training (gives you an overview of your training session, as well as weekly summaries) and the activity data (create new goals and see detailed info about your current progression), the Smart Coaching (which includes the 24/7 ACtivity tracking, Smart calories, Running Program and Training Benefit), Indoor Swimming Metrics (it can measure the distance and the pace, as well as the strokes per minute and strokes per pool length and it can also tell the swimming style: swimming freestyle, backstroke, breaststroke or butterfly) the ability to create Reminders, the StopWatch and the Timer.


The smartwatch part of the Polar M600 is divided into two parts: first, there’s the Android Wear 2.0 part which will work great while pairing with an Android device and secondly, there’s the iOS pairing, which will lack some of the features available with an Android smartphone. So, pairing the Polar M600 with an Android device will allow you to access the WiFi (not available with iOS), user wrist gestures and voice controls (available for both OS), read, reply and send texts (iOS only allows you to read texts), answer and reject incoming calls (both OS), initiate phone calls and listen to music from the smartwatch (available only with Android).
Note: If you have Bluetooth headphone and would prefer to leave your phone home while jogging or biking, you can download music directly to the smartwatch and listen to it, even if it’s not paired to a smartphone.

Inside the case, the Polar M600 is equipped with a MediaTek MT2601 chipset (dual-core ARM Cortex-A7 clocked at 1.2GHz), 512 MB of RAM and 4GB of internal storage (it also uses the Bluetooth® 4.2 technology and the Wi-Fi 802.11 b/g/n). Furthermore, the M600 is also equipped with a 500 mAh Li-pol battery which should deliver up to two days if you are a moderate user (and the smartwatch is paired to an Android device) and up to one day of moderate use if you pair the M600 to an iOS device. In workout mode, with GPS tracking and playing some music, the battery will be able to deliver about 6 hours before needing recharging.

7. Misfit Vapor 2



Following the success of the Misfit fitness trackers (popular mostly for the minimalist design approach and for the long battery life), the manufacturer decided to further push its smartwatch line, first by releasing the Misfit Vapor (after some delays and a bit of hype built-up) and afterwards, with its successor, the Misfit Vapor 2.

The much anticipated Misfit Vapor was a device built on top of the Android Wear 2.0 platform (which has proven to be a mistake), lacked GPS and didn’t really appeal to the large majority of users (not when the Apple Watch keeps raising the bar), so the Misfit Vapor 2 has the role of fixing the problems of its predecessor. And, in a sense, it succeeded as we now have a slimmer device, it’s one of the first smart watches to adopt the Wear OS and it has both GPS and NFC. But is that enough to regain the attention of the general public, now, when both the Galaxy Watch and the Apple Watch 4 are the top solutions in the smartwatch market?


The Misfit Vapor heavily focused towards minimalism, so it would appeal to previous users of a Pebble smartwatches (although the battery life was miles behind the Pebble series), featuring a simple circular brushed stainless steel case and the Vapor 2 didn’t change that much the design formula, keeping the circular case, but it is now slightly slimmer and it modified the bezel which now reaches a bit further within the screen (in my opinion, it gives the device a better look).

Furthermore, the manufacturer decided to make the smartwatch available in two size variants: 41mm and 46mm, so it’s easier to match it with your wrist. The metallic case does ensure that the smartwatch will survive drops or accidental bumps onto the furniture, but the bezel which surrounds the screen is still slightly elevated (just like on the original Vapor), so the display is left in a vulnerable position most of the time.


Despite being slimmer, the case remains relatively thick and the rear side arches towards the wrist (probably more than a design choice, as it also helps getting better readings from the heart-rate sensor), so it may not feel comfortable for everyone; the device is also on the heavier side, since it weighs about 2 ounces, but it is reasonably balanced (although you will feel its weight for a while).
To maintain the minimalist tone, Misfit has added a rotating crown on the right edge of the case to allow the user to operate the interface.

I suppose a sophisticated system such as the rotating bezel of the Galaxy Watch would have turned a lot more heads and the touch sensitive bezel (also called Virtual Touch Bezel) of the first Vapor was an interesting feature which was stripped in favour of the rotating crown but, while it should be enough to take full advantage of all the features of the Misfit Vapor 2, the crown feels a lot more rigid than on other smartwatches. Still, the touch-sensitive bezel of the Misfit Vapor was a cool, progressive choice, but for an athlete, it could become a bit of an inconvenience to not be able to quickly navigate the interface using either a physical dial or the good ol’ physical buttons, so I do appreciate the rotating crown despite it not being the best in its class.


At the top and the bottom side of the smartwatch case, there are two sections to attach the straps and the mechanism is very easy to use, consisting of two small round buttons that keep the straps secured into place (it also indicates that you won’t be able to use third-party straps, only those manufactured by Misfit). Furthermore, the case is available in various colours: jet black, rose (copper) and the nude stainless steel (each offering at least a couple of different straps). The Misfit Vapor 2 is equipped with an accelerometer, an altimeter, a gyroscope and a redesigned optical heart rate sensor (the sensor can be seen on the rear side of the smartwatches, were it touches your skin).

The heart rate sensor is surprisingly a lot more accurate than most other smartwatches from the competition and it will work fine even during intensive exercises (sure, a belt sensor will give the best results, but this is as close an one can get using a smartwatch). The Misfit Vapor ruled out the GPS sensor, but the Vapor 2 did implement it, so the user will get better metrics and stats.

It may not be as rugged as the other smartwatches in this list, but the Misfit Vapor 2 is a waterproof smartwatch, so you will be able to take it with you in the shower and it will withstand depths down to 164 feet (has a water resistance rating of 5 ATM) – the straps are also both waterproof and sweatproof. The smartwatch is also swim-proof, which means that it will measure your swimming sessions (it’s suitable for shallow swims, the manufacturer advertising water resistance for up to 30M + 10k stroke swim).


I do enjoy the fact that the bezels of the Misfit Vapor 2 are less thick (although it still lacks that bezel-less effect of the Apple Watch) and, in the middle, rests the round 1.2-inch or 1.4-inch OLED touchscreen display (depending on the size of the smart watch), a resolution of 390 x 390 or 454 x 454 pixels, a 328 ppi pixel density (an increase from the 326 ppi of the previous model) and it is protected by Corning Gorilla Glass 3 (that does a great job at keeping the scratches away). As expected, the AMOLED display is able to deliver deep black levels, a rich contrast and overall, the colours pop and make a great visual experience. Furthermore, the smartwatch does have an ambient light sensor (so it automatically adjusts the brightness to the environment) and it does have the Always On feature, where you can get various info displayed (such as the hour or email notifications).

To preserve the battery, you could go for the Raise to Wake wrist gesture in order to turn on the display only when you need to look at it, while keeping it turned off the rest of the time (I know, it looks less impressive this way, but you do gain at least a couple of hours of battery life – although the new Wear OS is more effective than the Android Wear in terms of battery life).


As said in the introduction, the Misfit Vapor 2 runs the Wear OS which is a major step up from the Android Wear 2.0 OS (that came with the original Vapor smart watch). This way, the smartwatch can take advantage of all the latest features: a better and improved user interface (including the better adjusted app launchers) and it did took some inspiration from the Apple Watch, adding complications to the watch faces (various data feed displayed on the watch face), there’s also the ability to write messages directly from your wrist and yes, unlike the original Vapor, the Misfit Vapor 2 does support Android Pay (so it has NFC built-in).

Since we’re dealing with an outdoors-focused waterproof smartwatch, one may expect that similarly to the Misfit Vapor, its successor would add its own proprietary means of tracking the user’s activities but it seems that the manufacturer decided to rely completely on the Wear OS , so the main available apps are Google Fit and Fit Workout. Both apps will be able to track your activities, including jogging, biking, swimming, elliptical, strength training and more.
Note: The Misfit Vapor 2 is able to connect to either an iPhone or an Android smartphone / tablet (it will work with Android 4.4 OS or higher and with iOS 9.3 or higher) via Bluetooth 4.1 Low Energy.


Inside the case, the Misfit Vapor 2 comes equipped with the Qualcomm Snapdragon Wear 2100 chipset and I understand that this decision was made to keep the cost of the device as low as possible, but, this chip is old and less efficient (the Wear 3100 would have been the perfect fit); furthermore, there are 512MB of RAM along with 4 GB storage memory that can be used for adding music that you can listen to later while working out (you can use Bluetooth headphones).

In terms of battery life, the 300mAh battery (330 mAh for the 46mm variant) will deliver a full day of light to moderate use (I know, it is a steep decrease from the Misfit fitness bands’ battery life) and, in order to charge the device, you’ll need to use the charging attachment that comes into the box (it will recharge the battery up to 80 percent in about an hour) – it seems that the smartwatch manufacturers continue to keep the annoying habit of creating proprietary charging cables and ports instead of converging towards a common standard.
Note: Besides Bluetooth, the Misfit Vapor 2 can also connect to a WiFi network.
