From the manufacturer
A Work of Art on Your Wrist
With three available colors and a range of 50+ watch face themes, 40+ with a matching Always-on Display. The GTR 2e can fit most of your outfits and occasions. Alternatively, personalize the watch face with your own images and use the customizable modular to focus on what’s important to you.
Lightweight and Extended Battery Life
Featuring a more sophisticated circuit design, a thinner body, and a high-capacity battery, the GTR 2e features an extended battery life to power you through up to 24 days of activity with typical use.
24-hour Heart Rate Monitoring
The Huami-developed BioTracker 2 biological tracking optical sensor in the watch can perform 24-hour heart rate monitoring. It covers heart rate zones and provides warnings when your resting heart rate is abnormally elevated.
Blood-oxygen Saturation Measurement
As one of the most important factors of human health, the GTR 2e includes the SpO2 level measurement function. When engaged in intense mental or physical activity, measure your blood-oxygen level if you feel uncomfortable to keep your health firmly in your hands.
Sleep Quality Monitoring for Optimal Performance
The GTR 2e offers in-depth sleep monitoring, which can accurately differentiate between the light deep and REM sleep periods, monitor the sleep breathing condition, provide quality analysis and suggestions for improvement based on a night of sleep, and recognize daytime naps over 20 minutes.
PAI Health Assessment System
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, unique to each user for easy understanding of your physical state.
Stress Level Measurement
Check your personal stress level - relaxed, normal, medium or high - anytime you feel pressured throughout the day, so you know when to relax and reduce it.
90+ Sports Modes
Activate one of the sports modes and the watch will produce a corresponding analytical report after you finish, to help you improve your exercise plan. Intelligent recognition of sports modes eliminates the need to manually select the sports mode, and 5 ATM water-resistance means you can wear it while you swim.
Liberate Your Hands
You can perform voice operations, like turning on sports modes or opening the heart rate monitoring function, on your watch without internet access with the offline voice control feature.
