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. 
The Gear 2 also includes a gyroscope, an accelerometer, and a heart-rate sensor. It also can control a TV or set-top box remotely using a built-in IR blaster, and it has the ability to function as a stand-alone music player. And its built-in camera—handily built into the watch itself rather than on the band, like the original Galaxy Gear—takes 2-megapixel stills and 720p video.
Samsung’s Gear Sport is not as stylish as Fossil’s Q watches, and because it runs Samsung’s Tizen operating system instead of Wear OS, it has nowhere near the app support of Wear OS. But as a smartwatch that shows your phone notifications and lets you respond to them, lasts all day, and tracks your recreational workouts, it is a great device. It’s not meant for competitive speed training, but it has built-in GPS and heart-rate sensing, offline Spotify storage, and a rotating bezel that’s much easier to use while exercising than a touchscreen. It does suffer from weak voice transcription and a barely-there S Voice “assistant,” but it fits a lot of core smartwatch functions into a relatively smart-looking package that’s better for fitness-minded wearers than our top picks.
How frustrating. I really -like- the idea of a smart watch... but it's so hard to find the right one. I'm not an exercise freak so heartrate monitors etc are useless to me. I really like the design of the Samsung watches with their bezels to control it, but the Tizen OS with it's limited apps puts me right off. The Access Grayson watch is beautiful, but the lack of NFC is a deal breaker for me - Google Pay with the convenience of a watch is part of the reason I'd buy one. I don't need to be able to put a sim in it... that's what my phone's for, but GOS would be nice for when I travel, and as a motorbike rider some level of waterproofing is a must. Guess I'm waiting for the next round of watches to see what's on offer.
I have the new version Samsung Galaxy watch 46mm. It is excellent. I do not have to use spotify premium to play music. I can simply add tracks (and images too) saved on my Note 8 phone. Bixby can open the apps without turning the bezel. The battery life is not 6 days as advertised, if used all day to make calls, text, listen to music, play games, check emails, read the news, search the internet, etc, then the battery lasts at least 3 days before recharging. There are several free watch faces available through the Galaxy app. This watch can also be used to make sos calls which can be preset for 911 or any contacts you wish to add. Then these contacts can call you back on low volume mode and listen for an hour. You can use this feature with a timer so if you accidentally activate it, you have time to turn it off before it makes the call. Adding a GPS app to this phone can allow you to take a screen shot of your location and send it if in a crisis. Of course the google app for navigation is also available for travel. You can use a wifi connection without your phone, if you turn off bluetooth and select wifi connection to your watch via phone. There is no need to buy the most expensive Samsung Galaxy with the built in sim. Also samsung pay is available on the watch. Of course it has Accelerometer, Gyro, Barometer, HRM, Circular Super AMOLED (360 x 360) Full Color Always On Display, Corning® Gorilla® Glass DX+. There is also a feature that tells you when to take deep breaths while it count the duration of inhaling and exhaling. This is great when you need to stay calm. The workout features are better than on previous Samsung watches. You can monitor calories, caffeine intake, water intake, track your sleep. You can swim with this watch. There is a water lock feature. Once you are out of the water you can expel water from the speaker by tapping a button. This watch has several other functions but It’s too much to write in a quick review. Of course you can add a security pin to your watch, use locator to find your phone or vise versa. You check youtube for more of the features. Samsung doesn’t have everything listed in specs. I’m still keeping my Ferragamo and Versace watches but I think I’m selling the rest of watch collection. The Samsung Galaxy watch has all of the features I need and changing watch bands is easy. I still recommend buying a screen protector and a tpu/silicone case or shell in case you drop your watch. Some sellers are offering a 2 year guarantee which includes accidents but I have the 1 year Samsung warranty. I would love this watch more if it had a nano sd slot. Specs are 768MB RAM and 4GB Internal Memory.
Flaws but not dealbreakers: Wear OS, Google’s name for Android for smartwatches, still feels like a work in progress, and in our testing, the Google Assistant voice feature frequently dropped responses—though that could improve via software updates. The Q line’s button at the 3 o’clock position is easy to accidentally trigger, bringing up Google Assistant and sometimes sending it nonsense questions. Wear OS also lacks a left-handed mode to allow you to switch the watch around. On the workout front, Fossil Q watches lack a heart rate monitor, so they’re not able to detect workouts or help with pacing; and the size of these models—and most Android smartwatches, really—and the touchscreen interface make workouts more difficult to monitor and pause than with a dedicated fitness tracker.
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.
The claim to fame on the Ticwatch Pro is battery life. The Pro offers up to 30 days of battery on a single charge. Of course, that all depends on how you use it. Mobvoi’s trick to improve battery life comes with the addition of a layered screen that acts as two displays. One is designed for use when the watch is idle, only showing crucial information such as the time to sip power. Under that is a standard OLED display that delivers the full Wear OS experience.
The touchscreen, button, and dial (what Apple calls the “crown”) help you zoom in and out and move between apps fairly effortlessly. With this easy navigation it’s easy to forget we’re typing on a screen slightly smaller than an Oreo. In particular, we loved Apple’s app homepage, which displays all of the apps as icons in a honeycomb-like display. You can use the touchscreen to move around, and the dial to zoom in or pan out, to precisely tap on the one you want.
Several of them also now support wireless charging which is hugely valuable as you avoid adding yet another cable and cradle to your dresser. Wireless charging pads are on the market that will charge your compatible iPhone and watch at the same time, and Apple is set to release its own official charging pad dubbed AirPower. Wireless charging is also available for Samsung smartphones and smartwatches.
The LG G Watch was the first one we tried that uses Google’s Android Wear OS (the Moto 360 and Samsung Gear Live do as well). It includes Google Now, the company's Siri-like "intelligent personal assistant." Say “OK Google,” and you can do Google searches, compose texts, and make requests of your watch (“Show me my steps” or “Set an alarm”). Google Now also offers up a stream of "cards" on the watch's face, with information it determines is relevant to you. If, for example, the card tells you how many minutes it would take you to get home from your current location, you can click on the card and get specific traffic and navigation information.
The Apple Watch boasts cutting-edge smartwatch tech including mobile payments with Apple Pay, stand-alone GPS, full waterproofing up to 50 meters, and thousands of apps. The user interface is very simple and attractive. It's easy to use and it has advanced, easy-to-use fitness tracking features, thanks to a plethora of sensors and an excellent heart rate monitor.
The Gear S3 also offers a dual-core Exynos 7270 processor, 768MB of RAM, and 4GB of storage. The watch also features sensors such as GPS, NFC, and even optional LTE. The standout features, though, include Samsung Pay (on any smartphone) and the rotating bezel. The Gear S3 is a pretty big watch, though, coming in at 12.9mm thick with a 46mm diameter.
Smartwatches are still a relatively new electronics category, but these devices are poised to hit the mainstream. This year we saw major players such as LG and Motorola throw their smartwatches in the ring, along with Samsung, Sony, and a host of smaller companies like Pebble and Martian. And Apple finally confirmed its entry, the innovative Apple Watch, expected to arrive early in 2015.
Dealing with notifications on a Wear OS watch has gotten better as the phone version of Android has improved its already impressive notification system and as phone app developers have taken advantage of new interactions. Many apps now send notifications with action options: For example, you can check a to-do as done, approve a payment, respond to a message, or, most often, just acknowledge something. The Q Explorist and Venture are no different than most Wear OS watches in relaying notifications, but in our testing they rarely showed lag in processing them, nor was either watch’s screen unresponsive to swiping or tapping options. Each watch’s vibration motor provides just enough buzz and movement to avoid missing things while not feeling like electric collar training for humans.
We pulled together a list of currently available smart watches that met these criteria from Apple, Android Wear, and Samsung. Our list included watches from tech brands like Apple, Asus, and Samsung, as well as fashion labels like Fossil, Nixon, and Tag Heuer. Then, we cross-checked with respected review sites, such as Tech Radar and PCMag, as well as tech retailer Best Buy, to make sure we weren’t leaving out any hidden gems.
