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.
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.
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.
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.
Samsung’s three second-generation smartwatches arrived with real improvements and refinements. At $300, the Gear 2 is the most sophisticated—and expensive—of the trio. The Gear 2 Neo is basically a less expensive version of the Gear 2: It has similar functionality, but it's housed in a plastic body instead of metal and has no built-in camera. And the slimmer Gear Fit is a hybrid smartwatch and activity tracker.
Samsung treads between smartwatch and fitness tracker, also packing in a heart rate sensor along with that GPS and its much-improved Samsung Health software. There's also the option of LTE (coming soon), if you wish for an untethered connection, with a standalone speaker for taking calls on the watch. It's now waterproof, too, adding swim tracking skills that are on par with the Watch Series 4.
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.
