Unlike the Apple Series 3, you can get third-party watch faces along with the default options. Many of these third-party faces also come with customizable widgets so you can manage layout without cluttering up your watch. From the homepage (which displays the time and date), you can twist the bezel to access fitness tracking data, like steps taken and calories burned, check the weather, change the song you’re listening to, or use any number of custom widgets.
The Watch 2 comes in two varieties, Sports and Classic. The former is a little cheaper, looking unsurprisingly much like a standard sports watch. The Classic is noticeably more attractive, with a premium-looking shell and included leather band. If you’re after something that’s appropriate at a nice restaurant as well as the gym, you may want to pay the extra money, but all features are otherwise the same.
A smartwatch is a wearable computer in the form of a wristwatch; modern smartwatches provide a local touchscreen interface for daily use, while an associated smartphone app provides for management and telemetry (such as long-term biomonitoring). While early models could perform basic tasks, such as calculations, digital time telling, translations, and game-playing, 2010s smartwatches have more general functionality closer to smartphones, including mobile apps, a mobile operating system and Bluetooth connectivity. Some smartwatches function as portable media players, with FM radio and playback of digital audio and video files via a Bluetooth or USB headset. Some models, called 'watch phones' (or vice versa), have complete functionality of a typical smartphone using LTE technology.
Our 19 contenders all promised to give us some distance from our phones by notifying us of incoming calls and texts. But we found that some smart watches were much slower than others at letting us know we had a call. It turns out the quality of the bluetooth connection determines how quickly you’ll be notified, with our worst performers only registering the call with two seconds to spare before diverting to voicemail (yes you, Montblanc) while others simply failed to display any calls at all.
Inside the Charge 3 are an accelerometer, gyroscope, optical heart rate monitor, and an SpO2 sensor for tracking blood oxygen levels. The Charge 3 is the third Fitbit device to include an SpO2 sensor, following in the footsteps of both the Fitbit Ionic and the Versa smartwatches. However, currently the SpO2 monitor lies dormant inside all of these devices as Fitbit hasn't made use of it yet.
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.
Wear OS’s chief problem, as we see it, is that it relies too much on input from swipes, taps, and other finger gestures. On a largish screen, such as on our top pick, this is less of a problem, but on smaller devices, trying to hit just the right button on the screen is like playing a very small version of Duck Hunt. The Apple Watch, by comparison, makes most of its buttons screen-wide rounded rectangles, which are easier to hit. On newer watches with three buttons, Wear OS also doesn’t utilize the physical controls beyond the home display (watch face), where they serve as shortcuts to apps or a list of apps.
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.
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.
The Martian Passport wants to give you the best of both watch worlds, by offering a mechanical, analog watch face and a small LCD. If you prefer a traditional-looking watch and want the “smart” component to be unobtrusive, this model may work for you. It comes in three varieties, all with silver bezels: a white face with a black or white band or a black face with a black band.
The Moto 360 was the first round smartwatch we got our hands (or wrists) on, and the design was a standout, for us. It looks like a traditional watch and fits more comfortably than rectangular smartwatches, but still packs the full functionality of an advanced smartwatch. Like the LG G Watch and Samsung Gear Live, it runs the Android Wear OS, allowing voice commands and pushing relevant information to the wearer.
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.
Most smartwatches are still more unisex than specifically made for women. Even though Fossil, Skagen, and Apple make very convincing unisex watches that women can actually wear, none of them are unapologetically feminine. If you, like me, have been waiting for the day when you can look at a smartwatch and say, "Oh my God! It's so cute!" your day has come.
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.
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 Q watches do not have built-in GPS or heart-rate sensors, and aside from one model (the black silicone strap Explorist), they are not made for heavy exercise tracking. The watches’ IP67 rating means that they’re dustproof and ready for rain, and that they can survive a short dunk in water less than 3 feet deep. For tracking your walking, movement, light bike rides or occasional runs or hikes, though, the watch does fine.
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.
