Amazfit GTR 2 e Obsidian Black Smartwatch

Thin and Light Bezel-less Design | HD Always-on AMOLED Display
All-round Health and Fitness Tracking | Ultra-long Battery Life.
The borderless design concept includes a large 1.39-inch AMOLED HD screen covered by curved glass, which naturally transitions to the carefully polished watch body, resulting in a better visual aesthetic and a wider field of vision. Dozens of free watch faces are available to download from the App for you to choose from and switch between. You can also edit the widgets on some watch faces to easily access the information you care about, or upload your own favorite pictures to the watch face background. The Always-on Display enables you to view the time even when the watch's other features are inactive, keeping you aware of every important moment in your life. The Huami-developed BioTracker™ 2 biological tracking optical sensor in the watch can perform 24-hour heart rate monitoring. It covers heart rate zones, keeping you aware of the exercise effect, and provides warnings when your resting heart rate is abnormally elevated. With water-resistance up to 50 meters, the watch is on par with traditional high-end watches, allowing you to wear it worry-free for daily use or while you swim.
PAI™ (Personal Activity Intelligence) is a health assessment system that uses algorithms to convert complex data such as heart rate, activity duration and other health data into a single, intuitive score, for users to easily understand their physical state. This feature covers most forms of exercise, and also personalizes the health assessment system for each user based on their health data.
