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.
Garmin, known primarily for its GPS and fitness devices, has taken one step closer to full-featured smartwatches with their Vivoactive 3 Music. This model doesn't run on Wear OS (Google's increasingly-popular OS for wearables), but it does offer thousands of free apps, watch faces, and more via Garmin’s ConnectIQ store. The Vivoactive 3 Music also comes preloaded with 15 sports apps to monitor your progress whether you're running, swimming, lifting, or doing yoga — because, at its core, Garmin is still all about fitness tracking
Like other Fitbit devices, the Charge 3 takes little effort to set up. It works with Android and iOS devices, and all you need is the Fitbit mobile app to use it. Choose the Charge 3 from the list of devices you can pair via Bluetooth to your smartphone or tablet, and follow the on-screen instructions. After setup, you may want to also edit basic information that the Charge 3 uses when tracking activity, such as your age, height, weight, and the activity metric you care most about (steps, active minutes, etc).
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 Fitbit Versa is nearly a full smartwatch, but the way it handles notifications prevents it from being a pick. Fitbit’s sleep, step, and workout tracking features beat our current picks’, and in our testing the Versa regularly lasted for four or more days between full charges. It lacks GPS, which the Ionic has, but it has a lower price as a result. You can choose from a decent variety of band types, although the bands are an odd 23 mm size (rather than a standard 22 mm), and slot in at an angle, making it hard to know if an unofficial band will fit. You can cache Deezer or Pandora radio stations to the Versa’s 2.5 GB of reserved space, control the music on your phone (after reconnecting your watch in “classic mode”), or transfer your own music to the watch, though it’s a tedious process involving a computer and cable. Where the Versa falls short is in working with notifications from your phone. The notifications pile up, and it can be a hassle to clear them; most notifications don’t expand to show more text; and though a software update has given you quick replies to select from, you’re limited to five of them. Like the Ionic, it’s more of a smartened-up fitness tracker than a fitness-savvy smartwatch.
The Galaxy Watch comes in two sizes, 46mm and 42mm, both with an OLED display and an “optimized” chipset that extends battery life. For the larger model, you can squeeze 6 days out of a single charge while the smaller model still offers up to 4 days. As you’d expect, the Watch also includes features like GPS, water resistance, and there’s NFC for Samsung Pay.
It doesn't get better than the Apple Watch Series 4. The new slimmer body and bigger screen make it sleeker and more stylish than ever before. The unique modern design works for both men and women. The smartwatch comes in 40mm and 44mm styles to fit wrists big and small. You can buy it in several finishes to match your style and there are dozens of Apple-made and third-party watch bands to make the Watch your own.
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.
It has all the sensors you might want if you’re an avid runner, but it goes so much further. If you’re a hiker, you’ll love the altimeter, air pressure read-outs, the clock showing the sunrise and sunset times, compass and the indicator of the day’s tide levels. You can also download map data for use offline, meaning if you’re the Bear Grylls type then you’ll be well prepared.
Our top pick for most people is the Apple Watch Series 4 with GPS (starting at $399), which has a huge display, ultra-fast processor, Raise to Speak Siri, fall detection and a built-in electrical heart rate sensor for taking on-the-go electrocardiograms. It also runs watchOS 5, which makes the watch even more useful with automatic workout-tracking, offline podcast playback and a Walkie-Talkie voice chat feature.
