In June 2000, IBM displayed a prototype for a wristwatch that ran Linux. The original version had only 6 hours of battery life, which was later extended to 12.[20] It featured 8 MB of memory and ran Linux 2.2.[21] The device was later upgraded with an accelerometer, vibrating mechanism, and fingerprint sensor. IBM began to collaborate with Citizen Watch Co. to create the "WatchPad". The WatchPad 1.5 features a 320 × 240 QVGA monochrome touch sensitive display and runs Linux 2.4.[22][23] It also features calendar software, Bluetooth, 8 MB of RAM and 16 MB of flash memory.[24][25] Citizen was hoping to market the watch to students and businessmen, with a retail price of around $399.[25] Epson Seiko introduced their Chrono-bit wristwatch in September 2000. The Chrono-bit watches feature a rotating bezel for data input, synchronize PIM data via a serial cable, and can load custom watch faces.[26]
The Huawei Watch 2 was one of the first smartwatches to launch with Android Wear 2.0 (now known as Wear OS), so delivers the handy Google Assistant straight to your wrist. Other improvements include more ways to respond to messages from your wrist, including a new on-screen keyboard. Wear OS doesn’t quite rival Apple’s watchOS for app support, but it has a decent stable of apps you’d expect.
The headline features are the new ECG monitor that unlocks the ability for serious heart health monitoring. It's been FDA cleared, so the feature can be used to detect heart rhythm irregularities - however, it's only in the US only for now. There's also a new fall detection mode that can let users access Siri to contact emergency services or a emergency contact. Apple's new smartwatch offers groundbreaking features and an improved design that makes it the standout option for iPhone owners right now.

Like other Fitbit devices, the Charge 3 takes little effort to set up. It works with Android and iOS devices, and all you need is the Fitbit mobile app to use it. Choose the Charge 3 from the list of devices you can pair via Bluetooth to your smartphone or tablet, and follow the on-screen instructions. After setup, you may want to also edit basic information that the Charge 3 uses when tracking activity, such as your age, height, weight, and the activity metric you care most about (steps, active minutes, etc).

Wear OS comes with a focus on fitness features, but unfortunately Huawei managed to simultaneously move too far in this direction and also fall short of it. It doesn’t come with a rotating side button for navigation, which is a shame as we really love the button on the LG Watch Sport. It does, however, come with great battery life and a stellar feature set otherwise.

Two watches from LG, the Watch Sport and Watch Style, were designed in collaboration with Google to launch Android Wear 2.0. The Sport is loaded with features, offering integrated GPS, LTE calls and texting (sharing a phone number with an Android phone), a speaker, a heart-rate monitor, two buttons, a rotating crown, and NFC support for using Android Pay directly from the watch. Reviews, however, suggest that the Sport suffers for those add-ons in thickness, comfort, and appearance. The Style, for $100 less than the Sport, is thinner and more comfortable; it offers Bluetooth and Wi-Fi but has a look that The Verge’s Dan Seifert describes as “kind of cheap” with a “homely design.” Neither model is easy to find at online vendors, especially in all colors.
Samsung’s new Galaxy Watch is the one to get if you need a smartwatch that can do it all. In our full review, we mentioned that it’s a fantastic all-around smartwatch, fitness, and health tracker. It has a great display, solid build, comes with Samsung Pay support, and offers wireless charging. Plus, the Tizen operating system has tons of great apps and watch faces.
The Charge 3 works continuously throughout the day to track steps, distance, calories, floors climbed, and heart rate—the standard array of activity data. Fitbit has been tracking these metrics for so long, without making many significant updates as of late, that they are business as usual on the Charge 3. I appreciated that most of the watch faces available for the Charge 3 show your real-time heart rate, either in a corner or at the bottom of the rectangular display. I like being able to glance down and know my pulse.
