Amazfit Stratos 3 GPS Sports Smartwatch

Train like a pro with the Stratos 3 GPS Sports Smartwatch from Amazfit. Equipped with 24-hour heart rate monitoring and Firstbeat algorithms, you can monitor your training with four pro-style metrics to help increase your performance and reduce the chance of injury: VO2 Max, recovery time, training load, and training effect. You can apply those metrics to whatever sport or exercise you choose, and the Stratos 3 can track 80 of them. It supports indoor workouts, outdoors with built-in GPS, and water-based sports with up to 164' of water resistance.
