Amoled screen 1.43 inches with excellent colors and deep blacks, always on display capability,
It has all the necessary measurements such as sleep, heart rate, blood oxygen, etc.
And its battery lasts from 7 to 20 days depending on the usage you will make.
Essential connection with an app on iOS and Android, and you can make calls as well as use voice commands thanks to the microphone it has.
Very nice design, you can change the strap if you want, and the only downside is that it does not support Greek in the menu and notifications.
