The Amazfit GTR 2 is equipped with the Huami-developed BioTracker™ 2, the second-generation PPG bio-tracking optical sensor, allowing it to perform 24-hour heart rate monitoring. It covers heart rate zones and provides warnings when your resting heart rate is abnormally elevated, keeping you aware of the exercise effect and reducing exercise risks.
Blood-oxygen Saturation Measurement
Blood-oxygen saturation is one of the most important factors of human health, so the GTR 2 has added the blood-oxygen saturation measurement function to keep you on top of your health. When engaged in long-term mental work, or physical activity such as participating in marathons or high-intensity outdoor sports, measure your blood-oxygen level if you feel uncomfortable to keep your health firmly in your hands.
PAI™ Health Assessment System. One Score to Summarize Your Physical State.
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 any form of exercise at any time and in any place, and also personalizes the health assessment system for each user based on their health data.
Sleep Quality Monitoring. Analyse Sleep Stages and Naps.
A good night’s sleep is a top priority in the modern world. Therefore, the Amazfit GTR 2 supports in-depth sleep monitoring, which can more accurately determine the sleep stage (the light sleep, deep sleep, REM periods), monitor the sleep breathing condition, and provide quality analysis and suggestions for improvement based on a night of sleep. The watch also recognizes naps over 20 minutes between 11am-6pm in order to record more complete sleep information.
Stress Level Monitoring.
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.
5 ATM Water-resistance. For the Deep-swimmers.
The Amazfit GTR 2 has a water-resistance of 50 meters, on par with traditional high-end watches. You can wear it worry-free for daily use or while you swim.
Extended 14-day Battery Life. Powered for Maximum Performance.
Featuring a more sophisticated circuit design, a thinner body, and a high-capacity 471mAh battery, the GTR 2 boasts a battery life of up to 14 days with typical usage. With this extended battery life, you are covered wherever your exercise takes you.
Music Storage and Playback. Your Playlist on Your Wrist.
Mobile music playback is supported with the Amazfit GTR 2, for you to control the music on your smartphone through the watch via Bluetooth connection. Also provided is a massive 3GB10 of local music storage space, enough to transfer 300-600 of your favourite songs to the watch through your mobile phone. So put down your phone, and listen to your favourite playlists while exercising, anytime and anywhere.
Bluetooth Call Function. Your Watch is Like a Phone, Too!
The Amazfit GTR 2 includes a microphone and speaker to let you answer calls on your watch when it's inconvenient to pick up your mobile phone. Connect the GTR 2 to your mobile phone via Bluetooth to ensure that you no longer miss important calls.
