Flaws but not dealbreakers: The Apple Watch requires an iPhone—if you have another kind of phone, you’re out of luck. While good Apple Watch apps are better than what you get for Android smartwatches, many are still very limited compared with their phone counterparts. And it can get annoying how aggressively the Apple Watch turns off its screen (to save energy) whenever it senses you’ve put your arm down.

If you wear the Q Explorist close to your hand, its case size and protruding center button can activate when you bend your wrist back, or if you’re wearing thicker gloves. The worst that happens is that Google Assistant is activated, and it either does nothing or tries to ask Google whatever nonsense the microphone picks up inadvertently. That can be annoying, and may cause you to size your watch band a bit larger, so the watch sits up your arm a bit more, clear of your wrist joint. Sadly, Wear OS lacks a “left-handed mode” to allow for turning the watch and its gestures the other direction.

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.[72] At IFA 2014 Sony Mobile announced the third generation of its smartwatch series, the Sony Smartwatch 3 powered by Android Wear.[73] Also, the Fashion Entertainments' e-paper watch was announced.[74]
If you’re trying to decide which one is right for you, allow us to help. The Versa is smaller and looks good on most wrist sizes, while the Ionic is probably best for large wrists. The other main difference is GPS connectivity — the Ionic comes with built-in GPS, while the Versa does not. However, you can pair it with your smartphone if you don’t mind bringing it with you on a run. 
The MetaWatch M1, like the Cookoo 2 and Martian Notifier, is a basic smartwatch. It shows alerts for texts, e-mails, social media updates, calendar appointments, weather, and Caller ID, and can control your phone's music app. The notifications are configurable in terms of what you are alerted to and how: whether via a vibration or on the watch’s display. Also built in are a timer, a stopwatch, and an alarm
Being able to customize the watch faces and layouts, made the Series 3 a shoo-in for our list of best smart watches. Much like you can customize the homescreen on your iPhone, you can change the layout of apps and even display the weather. While you can’t opt for third-party designs, you do have 12 different watch faces to play with. Tinker with color schemes, add or remove widgets (called “complications” on the app), and decide whether you want to have all twelve faces available on your watch (we always like having options), or cut back.
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]
We test every new smartwatch to gauge its design and comfort. If it’s not stylish and comfortable enough to get you from an early morning workout to the office to a night out, you probably won’t wear it every day. Most smartwatches are also fitness trackers, so we put all of its sensors to the test, from step counts to heart rate to GPS (when applicable).
