The Charge 3's screen has 40-percent more active space than the Charge 2 has, and it makes for a better touchscreen overall. From the watch face, swipe from top to bottom to reveal the notification drawer; from bottom to top to see the daily dashboard; and side to side to see available apps. Transitions between screen pages are smooth, and stick-figure animations in apps like the Exercise app move with ease.

For a device that gives you more of the functionality you enjoy with your smartphone, you’ll want to opt for a dedicated smartwatch. The leading players at the moment are the Apple Watch for iPhone users and the Samsung Gear S3 for those with Android phones. Apple Watch has its own operating system, Samsung employs its Tizen OS, and a host of other smartwatches use the Google Wear operating system.
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 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.
But the Ionic, the first of Fitbit's devices to include an SpO2 monitor, came out more than one year ago. It's frustrating to hear about exciting features that are "coming soon," when "soon" ultimately means not weeks or months, but years. While I understand it takes time and effort to develop features like this (especially if Fitbit hopes to pursue medical device clearance or approval from the FDA in the future), I don't think Fitbit should hype features that it isn't ready to let users put to the test.

The three buttons on the Q Explorist are useful and responsive, although the middle crown’s button action may be a bit too responsive. The newest versions of Wear OS allow you to set each of the two clicky side buttons (at the 2 and 4 o’clock positions) as a shortcut to any function on the watch when on the home screen. Clicking the center button wakes up the watch and brings you back to your “home” watch-face display, and holding it down activates Google Assistant. The Q Explorist’s center button has a mushier action to it than the Digital Crown on the Apple Watch, and its rotation is stiffer (more on that below), but it works, and turning a crown is easier to do in more situations than continually flicking upward on a touchscreen. The Venture lacks the two side buttons, and its crown cannot turn through lists. While the turning crown is a helpful upgrade, the the Venture’s push-button response is firmer and better than on the Explorist, and its screen response is fast enough to make the lack of physical input tolerable.

The screen is great, and the pre-installed watch faces make it stand out from rivals. Android Wear feels very samey across all devices, but it's a well developed OS. It's reasonably intuitive and simple, but there's a little too much swiping and tapping on the small screen. It also works across both Android and iOS, although iPhone functionality is limited (no apps etc.)
Many major phone apps have Wear OS counterparts, or at least most apps that make sense to have a dedicated watch app. You’ll likely find yourself using most watch apps less than you might think, but they are sometimes convenient for avoiding a phone retrieval. I use regularly use the Nest app for my home thermostat, Keep to take down a quick voice note, PocketCasts to control podcast episodes and playlists, and Stronglifts to time and track workouts. But I use these on my watch mostly when my phone is not at hand; none is easier to use than its phone version. As noted, most apps on your phone will provide notifications that can be acted upon through your watch. For the apps that you do use, the Q watches’ screen (identical to most of the Fossil group watches’ screens) is responsive enough to work with tiny buttons pressed by big fingers.
The era of the smartwatch is upon us – just look at the multitude of colourful straps and elongated or squarish screens people are wearing. From fitness trackers like the Fitbit and Garmin to the Samsung Gear and Apple Watch, there are a host of great options to combine fitness and activity tracking and message alerts on your watch, which incidentally will still tell you the time, along with the weather and even play your favourite music.
The RC-1000 Wrist Terminal was the first Seiko model to interface with a computer, and was released in 1984.[10] It was developed by Seiko Epson and was powered by a computer on a chip.[12] It was compatible with most of the popular PCs of that time, including Apple II, II+ and IIe, the Commodore 64, IBM PC, NEC 8201, Tandy Color Computer, Model 1000, 1200, 2000 and TRS-80 Model I, III, 4 and 4p. The RC-20 Wrist Computer was released in 1985, under the joint brand name "Seiko Epson".[13][14] It had a SMC84C00 8-bit Z-80 microprocessor; 8 KB of ROM and 2 KB of RAM. It had applications for scheduling, memos, and world time and a four-function calculator app. The dot-matrix LCD displayed 42×32 pixels, and more importantly, was touch-sensitive. Like the RC-1000, it could be connected to a personal computer, in this case through a proprietary cable. It was also notable in that it could be programmed, although its small display and limited storage severely limited application development.[10] The RC-4000 PC Data graph also released in 1985, was dubbed the "world's smallest computer terminal".[10] It had 2 KB of storage. The RC-4500 (1985), also known as the Wrist Mac, had the same features as the RC-4000, but came in a variety of bright, flashy colors.
For deeper integration with your Android phone, you can give Google's Wear OS platform a try with Fossil's $275 Q Control touchscreen smartwatch. It lacks GPS and support for NFC payments, which is why the Gear Sport is a better fitness-focused smartwatch for Android users, but Fossil's Google Assistant integration and stylish design make it a solid contender. However, smartwatches with Qualcomm's new Snapdragon Wear 3100 processor start shipping in October, so you may want to hold off until we put them to the test.
