Technology is smarter than ever, yet we’re working through an age of endless compatibility conundrums. Sonos speakers only work with other Sonos speakers, and the new Google Home can’t stream Amazon Prime Music or Apple Music. Then, there’s Samsung, whose Galaxy line of devices, including the Gear Fit2, IconX earphones, Gear 360 action camera and Gear VR, were all designed to work with Galaxy smartphones.
The Note 7 recall spelled catastrophe for that whole system. Not only did it deprive people of a potential iPhone killer, but it also made it likely for Samsung’s other devices to take a hit. Fortunately for Samsung (and Android users), the company’s shares, after an initial plunge, bounced back. Samsung still has two of the best Android smartphones of 2016, after all, in the Galaxy S7 and Galaxy S7 Edge. And its new Gear S3 smartwatch, which started shipping in November 2016, is possibly the best smartwatch to come to market.
The Gear S3 is the next generation of Samsung’s highly praised Gear S2 smartwatch from 2015. It has the same rotating bezel as its predecessor, making it easy to scroll between apps, of which there are thousands to choose from; an IP68 waterproof rating; a built-in heart-rate monitor; a GPS tracker; and last but not least, an improved battery that can last three days between charges, which can also charge wirelessly. The Gear S3 also supports Samsung Pay, which is new. But the real difference is its size and design.
Samsung Gear S3: Specs

Display: 1.3 inches
Connectivity: 4G LTE, Bluetooth
Durability: IP68
Fitness Features: GPS, barometer, accelerometer, pedometer, altimeter
Battery: 3 Days
With the right customizable face (which you can choose directly on the Gear S3, instead of on the phone), the Gear S3 has the look of a legitimate mechanical timepiece. It’s significantly larger, with a 46mm diameter (compare with the Gear S2’s 42mm diameter), and could probably pass for a dive watch. There are two Gear S3 models that you can choose from: the Classic and Frontier. Both have the same diameter, but the Frontier is the more rugged-looking, slightly heavier option.
