Bright & Clear HD AMOLED Display Elegantly crafted with curved glass and protected by anti-fingerprint coating, the HD AMOLED display is where style comes full circle. Choose from over 80 watch faces, along with the new Portrait Mode option - which lets you upload three of your favorite pictures, and alternates between them every time you wake up the display. Super Slim & Light Design with Stainless Steel When it comes to style, think outside the box! At only 9.25mm and 24.6g, the Amazfit GTR Mini has a slim and light round design that's as comfortable as it is classy. The sparkling stainless steel frame and button add an extra touch of elegance to the fashionable design. Ultra-long 14-day Battery Life The Amazfit GTR Mini acts as a dynamic power-up for your action-packed lifestyle, and provids the battery power you need to crush your goals for up to two weeks at a time, with typical usage. 120+ Sports Modes The smartwatch can track data for over 120 different sports, so you can easily find an activity that suits you. Turn on the auto-detection feature and the watch can even intelligently recognize seven sports movements, and prompt you to open the matching sports mode. Working out has never been so easy! Sleep Quality Monitoring & Menstrual Cycle Tracking The Amazfit GTR Mini can track your sleep quality through the light, deep and REM sleep stages, as well as your sleep breathing quality - and can even track daytime naps. You can also use the watch to record your menstrual period, and it will intelligently predict the time and length of the following menstrual and fertile periods. Easy 24/7 Health Management The smart watch's sensor works in tandem with the health-centered Zepp OS 2.0 to provide 24-hour monitoring of your heart rate, blood-oxygen saturation (SpO₂) and stress level. You can also simultaneously test these three metrics in one tap, for a result in as quick as 45 seconds. Strong and Accurate GPS Tracking The Amazfit GTR Mini uses a patented circularly-polarized GPS antenna, which allows it to pick up almost twice as many satellite signals as other smartwatches with a regular antenna. The watch also supports five satellite positioning systems for greater global coverage. 5 ATM Water-resistance The smart watch can withstand the equivalent of up to 50 meters' water pressure, so head for a swim with the Pool Swimming and Open Water Swimming modes!
