At the 2016 Consumer Electronics Show, Razer released the Nabu Watch, a dual-screen smartwatch: integrates an always-on illuminated backlit display, that takes care of some pretty standard features as date and time, and a second OLED screen, which is activated by raising your wrist, allows access to extra smart features. Luxury watchmaker TAG Heuer released TAG Heuer Connected, a smartwatch powered by Android Wear.
No other smartwatch offers this much variety and customization, especially when it comes to female-friendly options. The Apple Watch is the only smartwatch I've ever worn regularly each day for months on end. I've reviewed dozens of WearOS watches, and although many of them are nice looking as well, they're not as fully featured or easy to use as the Apple Watch.
The style offerings for smartwatches have improved dramatically, and your options are no longer limited to “large, nerdy and round” or “large, nerdy and square.” Still, even with more than 300 Fossil-branded watches planned across 14 major watch and fashion brands, smartwatches are generally much wider and chunkier than standard watches, as the size needed to accommodate the electronics and battery lends itself to bolder, more pronounced styles.
The Amazfit Bip is thin and light, looks like an Apple Watch, has a lot of sensors inside—GPS, heart rate, accelerometers, barometer, and compass—and can run for about 30 days (which we confirmed) between charges, all for around $100. Those facts are compelling, but actually using the watch is frustrating, and it doesn’t do any one thing well. The GPS and heart-rate monitors can be slow to start, sometimes drop out, occasionally have wild inaccuracies, and produce results notably different from those of running watches and dedicated fitness bands. The screen is also dim and noticeably low-resolution, and the phone software for managing the watch is dense and unintuitive on Android. (We didn’t test iOS, but the reviews imply that it’s not much different.) The watch materials are plastic and rubber, and look and feel like it. Those are all trade-offs you could reasonably make if you just wanted a Pebble-like smartwatch that tracked steps and showed notifications, but even there, the Bip does not succeed: It often dropped connectivity with my phone (a Pixel 2), and it cannot show emoji—getting a dozen blank squares when someone sends you a thumbs-up sign is not helpful. If all you care about is battery life, the Bip has that, but it lacks useful functions while it’s charged up.
Next is the big focus on health and fitness. The Apple Watch can monitor your heart rhythm and suggest you see a doctor if it detects something irregular, it can call the emergency services you've fallen over, and it will keep you healthy by tracking your run. These potentially life saving features are a major reason people are ditching their traditional watches for an Apple Watch.
Software may include digital maps, schedulers and personal organizers, calculators, and various kinds of watch faces. The watch may communicate with external devices such as sensors, wireless headsets, or a heads-up display. Like other computers, a smartwatch may collect information from internal or external sensors and it may control, or retrieve data from, other instruments or computers. It may support wireless technologies like Bluetooth, Wi-Fi, and GPS. For many purposes, a "watch computer" serves as a front end for a remote system such as a smartphone, communicating with the smartphone using various wireless technologies. Smartwatches are advancing, especially their design, battery capacity, and health-related applications.
For all of you outdoorsmen, Casio returned to IFA this year with its latest Pro Trek watch. The Casio WSD-F30 takes the same great features of previous generations and slaps them inside of a slightly slimmer body. The 60.5mm × 53.8mm × 14.9mm body is still pretty huge, but it’s considerably smaller than what came before it and still maintains 5ATM water resistance, MIL-STD-810, and even low-temperature resistance.
That same attractive stainless steel design is here. The 240 x 240 pixel display at the heart of the body is by no means the brightest or most vibrant you'll find, but crucially delivers strong visibility in most workout conditions whether you're sweating it out indoors or outside. However, there is no touchscreen or touchpad here, you'll have to resort to pressing some buttons - that could be a deal-breaker for some, but we're sure it won't be a massive one for most.
Wrist watches have been fashion accessories since they were first invented. The first generation of smartwatches were dull, chunky looking devices, more functional than fashionable. How things have changed. You can select from thousands of watch faces and even design your own. Wrist straps can be swapped out and designers have come up with clever quick-release clasps for them, knowing that the need to charge your watch regularly will see you needing to remove it quickly.
The Asus ZenWatch 3 was a previous top pick for a Wear OS smartwatch. As of now, it has reached the end of its Wear OS updates (after a very long delay getting to Android Wear 2.0). Its rotating crown does not actually work to turn or scroll anything on the screen. Its proprietary watch band connections mean that your options are limited to what is available from third parties on Amazon. And the watch is hard to find new.
Samsung released its Galaxy Watch, a follow-up to the Gear S3, a prior pick. The Galaxy Watch is available in 42 mm and 46 mm configurations, with either a Bluetooth-only connection or Bluetooth plus LTE from T-Mobile (at launch). The biggest update seems to be the battery life, which the company claims will last for days between charges. The Bluetooth version of the Galaxy Watch is available for $330 for the smaller version and $350 for the larger (46 mm) model; the 42 mm LTE version is available for $380 and the 46 mm is $400.

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. 
Garmin has been putting out go-to smartwatches for sports lovers for a while now. Running, cycling, swimming, golf - Garmin has had us well and truly covered. Despite the Forerunner name, the 645 Music is more in the mould of the Vivoactive 3 Music. It's got a similar look and also brings the music this time. This helps make the Garmin more of a smartwatch rival to the Apple Watch, Samsung Gear or Fitbit Ionic than before.
The Charge 3's module weighs in at 20 percent lighter than that of the Charge 2, so it won't weigh down your wrist when you're wearing it. I barely noticed it on my wrist when I paired it with Fitbit's woven bands, which are made of a feather-light fabric material. If you're looking for the band that both complements the device's weightlessness and remains fashionably flexible enough to go from the gym to the office, I'd go with a woven option instead of the standard silicone one.
Other reviewers also like the Q watches. Simon Hill at Digital Trends writes that the Q Explorist is “an attractive smartwatch to use with an Android phone that will blend in at work or play at an affordable price,” and that, aside from the Apple Watch and the Gear Sport (for Samsung phone owners), the Q Explorist “compares favorably with the rest of the field.” Gerald Lynch at TechRadar summarizes the Venture as “a sharp-looking, comfortable smartwatch with a great display and responsive processor,” but knocks it for lacking GPS and a heart-rate monitor. Matthew Miller at ZDNet believes the Explorist and Venture are “priced fairly for nice looking fashion watches that also serve as smartwatches.”
We actually got our hands on over a dozen of these smart watches just to get a feel for what it was like to use them. While all of them came with at least one main button (or a home button if you’re an iPhone-user), the ones that stood out had scrolling down to a science. On such a small screen, swiping isn’t always the most ideal form of navigation. Some of the best smart watches for navigation, we found, had twistable dials or bezels you could turn.
