The Xiaomi Watch S1 Active is a more robust update of Xiaomi’s original wristwatch, the Watch S1. It provides nearly the same functionality as its predecessor, but in a form factor that is more conducive to use while physical activity.

Support for major satellite networks for precise tracking of outdoor exercises, continuous monitoring of heart rate and blood oxygen levels, Near Field Communication (NFC) for making purchases, and long battery life (during and after) are all part of the package.
