Although rectangular is the most common design, there are smart watches that have a circular display similar to regular watches. The Apple Watch is only available in the rectangular design. The circular design is available in the Samsung Gear S2, Moto 360, and LG G Watch R models. Many models have changeable straps, so you can dress casual, sporty, and formal.
Yes, it can monitor your health and fitness. You should choose one that has a pedometer to count your steps. An accelerometer is helpful in determining acceleration. Acceleration can be used to detect when you fall. A heart rate sensor can be used to monitor your heart beats. Some will report the amount of calories you consume and even display a report of your health at day’s end.
Plus, these smartwatches are made by Fitbit, so they’re incredible fitness and health trackers. They both offer 24/7 heart rate tracking, on-screen workouts with Fitbit Coach, over 15 exercise modes, GPS (Connected GPS in the Versa’s case), and swim tracking thanks to their 5ATM rating. There’s also room to store your music, as well as Fitbit Pay support (Ionic and Special Edition Versa only).
Of the three second-generation Samsung smartwatches, the Gear Fit is the most creative and stylish departure from the original Samsung Galaxy Gear. It's just as much an activity monitor as it is a smartwatch, and it has a markedly new look—slim, sleek, and light. It also has an unconventional sideways display that’s unlike any of the other tested watches; it takes a bit of wrist-twisting to view it. (You can opt to view your display vertically, but you'll be reading a lot of truncated words that way.)
Out of a vast field of similar watches, we picked the Q Explorist and Q Venture because of their middle-of-the-road prices, wide availability, and variety of styles. These two models are flagships for the Fossil Group’s collection of 14 style brands producing more than 300 planned smartwatches. This means that if you find a smartwatch from Diesel, Skagen, Tag Heuer, Kate Spade, Movado, or another Fossil-connected brand that fits your style better, you should feel free to buy it, because it will have roughly the same internal hardware as our picks.
Fitbit Versa: The Fitbit is the health tracker for the masses and they have a model for every need. But the best option for adults who do a moderate amount of exercise and just want to keep tabs on their general fitness (ie: most of us), the Fitbit Versa is a great choice. It's an entry-level smartwatch. For more on the Fitbit Versa’s various attributes, read my in-depth review. ($350)
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.
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.
