The shape of the Amazfit T-Rex Pro is tough and solid with distinct angles. Having passed 15 military-grade tests1, the watch can battle with you through hot deserts, humid rainforests and polar glaciers. Witness endurance that braves the elements with ease
The four Global Navigation Satellite Systems supported offer rapid positioning with a high-degree of accuracy. No matter where you go, you’ll always know where you are8.
PAI is a health assessment system that uses an algorithm to transform complex information such as heart rate, activity duration, and other health data into a single numerical value unique to each user. The PAI health assessment system supports most workout modes, regardless of time or location, and in addition, also creates a customized health evaluation for each user to offer a personalized user experience.
The Amazfit T-Rex Pro features over 100 sports modes7, and can be used to monitor critical data such as workout heart rate, distance traveled, movement speed, and calories burned in real time for most sports modes, to help you track and improve your athletic performance.
In high-altitude areas, every meter you travel upward comes with greater challenges. The Amazfit T-Rex Pro will therefore alert you whenever it detects that you experience major altitude changes9, and prompt you to take the blood-oxygen saturation test. This test can also be taken whenever you feel uncomfortable, in order to better protect your body.
The Amazfit T-Rex Pro offers 24-hour heart rate monitoring, and is able to provide instant alerts for high heart rate. Heart health is a top priority, and so your Amazfit T-Rex Pro tracks it at all times, and can also record your heart rate variability (HRV) throughout the day, to monitor your stress level. Learning to relax is the first step in protecting your health.
Sleep quality is essential to health, and so the Amazfit T-Rex Pro serves as your personal sleep assistant. The watch can recognize different sleep states – such as the light, deep and REM sleep stages, as well as daytime naps, and monitors any potential breathing problems during your sleep15
The Amazfit T-Rex Pro notifies you of any incoming text messages or calls, scheduled alarms and events, to prevent you from missing any important information. It can also easily control music playback on your mobile phone via Bluetooth, so that you can enjoy your favorite playlists on-the-go.
