The Nixon Mission is a rugged 'action' smartwatch, and we really like it. The durable casing can take a bashing, while the Qualcomm Snapdragon Wear 2100 keeps things ticking inside. It runs Android Wear, but also comes with some useful pre-installed apps which track real-time surfing and snowboarding conditions. It's water resistant to 10ATM (roughly 100m), and best of all, it comes in Orange.
The company claims that the SpO2 monitor will help its devices look for signs of sleep apnea and other breathing problems, potentially great features for devices that are meant to be worn 24/7. It'll be used primarily in Fitbit's forthcoming Sleep Score Beta, which further analyzes sleep quality using heart rate and breathing data. Starting sometime this November, users with devices that only have heart rate monitors can get a "sleep score" after each night's sleep. Those with an Ionic, Versa, or Charge 3 will presumably have better data thanks to the SpO2 monitor collecting breathing data.
The Huawei Watch 2 comes into its own if you’re looking for a smartwatch that can double as a sports watch, thanks to built-in GPS and a heart rate monitor on its rear. Use the 4GB of built-in storage to save your Google Play Music playlists offline and you can pair Bluetooth headphones for a phone-free experience. The Huawei Watch 2 will work with Huawei’s own suite of fitness apps, Google Fit, or other third-party apps such as Strava, offering excellent choice.
Its only drawback is its use of Samsung’s own Tizen OS. Tizen is a custom OS that’s based on Linux. On paper it’s pretty good, letting you pair the Gear S2 with any Android smartphone, not just Samsung Galaxy phones. But it’s nowhere near as developed as Wear OS, which itself isn’t perfect. There aren’t nearly as many apps available as the Wear OS app store, but the core functionality is at least present from what is available.
Samsung’s three second-generation smartwatches arrived with real improvements and refinements. At $300, the Gear 2 is the most sophisticated—and expensive—of the trio. The Gear 2 Neo is basically a less expensive version of the Gear 2: It has similar functionality, but it's housed in a plastic body instead of metal and has no built-in camera. And the slimmer Gear Fit is a hybrid smartwatch and activity tracker.

Smartwatches, like smart phones, can also run apps, via your smart phone or right on the watch. These include health and fitness apps (thus the comparison with activity trackers), apps that control functions such as music and the camera on your phone, navigation apps, and more. Because most smartwatches have open software platforms (at least so far), developers are coming up with new and innovative apps that can increase the functionality of the devices.
Unfortunately, you won't be able to respond to alerts (like messages and emails) from the Charge 3. That's a feature sequestered to smartwatches, but you can see most of the content of an alert on the device's screen. Considering how narrow the device's screen is, reading through a long email won't be the most comfortable experience. But at least that message will be glanceable on your wrist, as will news headlines, text messages, and other alerts as well.
The top smartwatches that debuted at the 2017 Consumer Electronics Show included the Casio WSD-F20, Misfit Wearables Vapor and the Garmin Fenix 5 series. Apple released on September 22, 2017 their Apple Watch Series 3 model which offers built in LTE cellular connectivity allowing phone calls, messaging and data without relying on a nearby smartphone connection.

If you like traditional analog watches and want just a few smart features, the Cookoo 2 might be more appealing than its more full-featured rectangular competitors. Behind its hands is a monochrome display that delivers basic notifications: incoming calls (with Caller ID), missed calls, texts, e-mail, social media alerts (for WhatsApp, Line, QQ, WeChat, Skype, Facebook, Twitter), and calendar alerts. Just bear in mind that it's a very basic smartwatch, with little configurability.
All but the Martian Notifier claim some degree of water resistance: the LG, Samsung, and Motorola models can survive underwater up to 1 meter for 30 minutes, the Cookoo2 up to 100 meters, and the MetaWatch up to 3ATM, which is equivalent to 30 meters. Only the Martian and Motorola models claim to have scratch-resistant screens (the Martian has an anti-scratch acrylic crystal and the Moto 3 uses Gorilla Glass 3).
The launch of Samsung's Gear S smartwatch was covered by the media in late August 2014. The model features a curved Super AMOLED display and a built-in 3G modem, with technology writer Darrell Etherington stating on the TechCrunch website, "we’re finally starting to see displays that wrap around the contours of the wrist, rather than sticking out as a traditional flat surface." The corporation commenced selling the Gear S smartwatch in October 2014, alongside the Gear Circle headset accessory. At IFA 2014 Sony Mobile announced the third generation of its smartwatch series, the Sony Smartwatch 3 powered by Android Wear. Also, the Fashion Entertainments' e-paper watch was announced.
Bottom line: Some fitness trackers work equally well with an iPhone or Android device, but some smartwatches are built to pair with Android phones so you won’t enjoy full functionality and pairing on an iPhone. The Apple Watch only pairs with the iPhone so is off limits to Android users. Your existing phone choice will play an important part in choosing a smartwatch.

Why we like it: Compared with a smartwatch or fitness tracker, a dedicated GPS running watch is focused on one category of exercise: outdoor movement. GPS watches offer the fastest GPS signal lock-on and more-precise maps, while also showing up to the second details on your pace, heart rate, mile split times, and a host of other stats on an always-on display. The physical buttons on a GPS watch are easier to use while moving (and without looking), rather than having to swipe or tap on a tiny glass screen. A GPS watch’s longer battery life can better handle endurance events than a smartwatch. And the software and apps behind a good GPS watch provide more statistics and training programs to improve your efficiency. While GPS watches can show notifications, the weather, and a few other smartwatch-like conveniences, they’re much more limited in what can be done from a wrist than a smartwatch—or even a fitness tracker like the Vívosmart.
While you're not getting Spotify or Apple Music here, you are getting enough storage for 500 songs with a process that's fairly easy. You just boot up Garmin Express, select the Music tab and choose which of your own music you want to port over. If you do want to sync over playlists from a streaming service, your only options are iHeartRadio and Deezer.
The Sofie, on the other hand, is designed for women with jewelry inspired accents. It has a smaller 1.19 inch 390×390 AMOLED display, and a smaller casing at 42mm. As mentioned, pricing starts at $350 for either variant and goes up depending on options. Sales are available from MichaelKors.com (Grayson — Sofie) and also from outlets such as Amazon.

Fitbit Versa: The Fitbit is the health tracker for the masses and they have a model for every need. But the best option for adults who do a moderate amount of exercise and just want to keep tabs on their general fitness (ie: most of us), the Fitbit Versa is a great choice. It's an entry-level smartwatch. For more on the Fitbit Versa’s various attributes, read my in-depth review. ($350)
These new smartwatches build on a pretty familiar package. Both are powered by the Qualcomm Snapdragon Wear 2100 processor and run on Wear OS. Both also get GPS, NFC for Google Pay, and heart rate sensors as well. The Venture is the smaller of the two, measuring in at 40mm with an 18mm band. The Explorist, on the other hand, is a 45mm watch with a 22mm band.
I visited the Fitbit app more than I usually do during the first day of wearing the Charge 3 so I could manage notifications. This device is the first tracker to go beyond the basic call, text, and calendar alerts that most Fitbit trackers can receive. The Charge 3 can alert you to any and all happenings on your smartphone if you want. In the notification panel in the Fitbit app, you can choose which apps you want to receive alerts from—turn on all of them so you never miss a beat, or only turn on the apps that are most important to you.
Wirecutter writers have been researching, testing, and writing about smartwatches since early 2013, just after the first Pebble watches were shipped to Kickstarter backers. I’ve personally worn nearly every notable smartwatch since that first Pebble and have written about them for a number of publications, including IT World and Fast Company. I also have extensive experience with Android phones, having written the (since outdated) Complete Android Guide and numerous articles about Android. I also contribute to and help edit the Wirecutter guide to the best smartwatch for iPhones.
You’d be amazed how hard it is to text something as simple as “hi” on many smart watch interfaces. Still, most designs take this into consideration. We tested all kinds of watches from auto-scrolling screens where you drew the letters with your finger to pre-smartphone layouts more akin to the alphanumeric layout of a payphone keypad. While the drawing features were nice, we felt that the texting was a little more manageable on keyboards.
