Amazfit GTR 4 Superspeed watch + scale black/silver W2166EU1N (W2166EU1N)

The sports watch Amazfit GTR 4 is an extremely classic and functional model, with stunning colors on the 1.43" HD AMOLED display covered with tempered glass and an Anti-Fingerprint coating. Navigation through the menu is greatly facilitated by the classic rotating crown, which also serves as a button. You can also use a voice assistant to operate the watch: Alexa Built-in or Offline Voice Assistant, depending on whether you are online or offline. The GTR 4 is equipped with essential sensors such as a pulse oximeter, barometer, magnetometer, and gyroscope, allowing for even better training.

This model is suitable for everyday use as well as for various types of activities. It is equipped with a powerful 475 mAh battery that provides up to 50 days of operation in watch mode and up to 44 hours during training with GPS enabled.  

The improved BioTracker 4.0 PPG biometric sensor used in this model allows simultaneous recording of multiple vital parameters. With its help, you can easily assess your health status, thanks to information such as heart rate, blood oxygen saturation, stress level, and breathing rate. PAI Health Assessment also takes daily activities into account when evaluating and presents the current health status. Heart rate data are extremely precise, and their measurement is not disturbed by hand movements during exercise.  

The watch combined with the included Amazfit Smart Aurora scale offers unlimited possibilities for monitoring the body's fitness level, as well as the ability to create personalized training plans.    

GTR 4 is equipped with a GPS module that uses a dual-band antenna, similar to those used, among others, in aviation, allowing you to use super-accurate navigation without interference, regardless of your location. You can upload your routes from the app, track them in real time, and when you need to quickly return to the starting point, the navigation will display the shortest route in a straight line.

The improved BioTracker 4.0 PPG biometric sensor used in this model allows simultaneous recording of multiple vital parameters. With its help, you can easily assess your health status, thanks to information such as heart rate, blood oxygen saturation, stress level, and breathing rate. PAI Health Assessment also takes daily activities into account when evaluating and presents the current health status. Heart rate data are extremely precise, and their measurement is not disturbed by hand movements during exercise.  

The ZEPP OS 2.0 operating system is intuitive enough that you can easily navigate the menu and find the apps you are interested in. Animations are smooth, and the user interface is specially adapted and designed to consume less energy. Additionally, the selection of mini apps has been expanded and it is possible to add your loyalty cards through the Zepp App. This way, you will have all your cards at hand. A new feature is also the Fall Detection function, which will help you send a request for help to your designated contacts if something bad happens.  

The photos shown below are for preview purposes only. The watch is black with a fluoroelastomer strap! 

The included scale of the Amazfit Smart Aurora set is an extremely sensitive device, which records weight fluctuations as small as 50 g! This is thanks to a precise G-shaped sensor . By calculating your BMI with the device, you will be able to tailor your training plan to your needs.

With its help, you will analyze as many as 16 health indicators, including the ratio of body fat, muscle mass, water content in the body, protein ratio, body age, and determine your ideal body weight. The scale transmits previously measured body data to the app, allowing the app, after calculating calories burned during exercises of one of the 18 supported sports, to develop an appropriate workout plan on its own.

The scale synchronizes all data with the cloud, so you can check it in the Amazfit app at any time. Data synchronization is facilitated by connectivity via Wi-Fi and Bluetooth. Aurora supports up to 10 app accounts, which can be used by up to 12 family members.
