The watch is available in one size (44mm) with bands in either black or blue. It also works with any 20mm watch bands. Like the Galaxy Watch and Gear S3, the Gear Sport Watch has a rotating bezel for navigation. It also has an accelerometer, ambient light sensor, barometer, heart rate monitor, and gyroscope.
The watch runs on Samsung’s Tizen OS, not Google’s Wear operating system, and it’s compatible with Samsung smartphones, Android phones running Android 4.4 and later with at least 1.5GB RAM, and the iPhone 5 or later with iOS 9.0 and above.
These are the five best Samsung Gear Sport watch features.
