Amazfit GTR Mini Strong & Accurate GPS Tracking: From cycling through city streets to walking through wild woodland – wherever your travels take you, support for five satellite systems means the Amazfit GTR Mini will be able to pinpoint your position with the kind of precision only provided by Amazfit’s patented circularly-polarized GPS antenna technology. 14-day Battery Life: The Amazfit GTR Mini packs the power-efficient software and hardware to conserve the battery power you need to crush your goals for up to two weeks with typical usage, and 20 days with battery saver mode. 120 plus Sports Modes & Smart Recognition: Whatever workout gets you pumped, the Amazfit GTR Mini can likely track data for it. Check your steps, calories burned, and more for over 120 different sports, and get a post-workout report when you’re done. The smartwatch can even automatically detect seven sports, so it’s easy to jump into action. 24/7 Heart Rate, SpO₂ & Stress Monitoring: The Amazfit GTR Mini is empowered by the health-centered Zepp OS 2.0 to provide 24-hour monitoring of heart rate, blood-oxygen and stress levels. And you can get a result for all three metrics in as fast as 15 seconds with the super-convenient One-tap Measuring function. The watch can be set to send a reminder if it detects abnormally: high or low heart rates, low SpO₂ levels, or high-stress levels.
