ADVENTURE-READY DESIGN Endurance to Match Your Own 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. Toughness from the Inside Out The Amazfit T-Rex Pro is a titanic combination of practicality, strength and comfort. YOUR PARTNER IN EXPLORATION Hit the Road, and Face Whatever Comes The Amazfit T-Rex Pro is high-level exploration partner, supporting four Global Navigation Satellite Systems, 10 ATM water-resistance, a blood-oxygen saturation measurement system, a weather tracker4, a sunrise and sunset monitor, a current moon phase display, a compass and barometric altimeter, ultra-long 18-day battery life6 with typical use, and over 100 different sports modes. Explore the Unknown 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 are. Ride the Tide and Make a Splash With a 10 ATM grade, the Amazfit T-Rex Pro is water-resistant to a depth of up to 100 meters, so you can surf, swim, or explore the mysterious underwater world together. Ascend Safely with Blood-oxygen Saturation Measurement 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 changes, 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. Exercise to the Fullest and Track Your Every Move The Amazfit T-Rex Pro features over 100 sports modes, 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. The FirstBeat algorithm assesses specialized data such as your maximum oxygen uptake, full recovery time and training load, to quantify your accomplishments after each challenge. Our latest self-developed ExerSense workout recognition algorithm automatically recognizes eight sports modes and records corresponding workout data. PROTECT YOUR HEALTH AND KEEP FIT Keep Your Progress Ticking with Heart Rate Monitoring 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. Get Personalized Evaluations with PAI 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. Understand Your Rest with Sleep Quality Monitoring 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 sleep.
