1.58 AMOLED screen

4 GB internal storage

A new ECG function as well as a skin temperature sensor, and the standard optical heart rate sensor

Wi-Fi, NFC, Bluetooth 5.0 and Built-in GPS

Water resistant up to 50 meters

Also part of the package are a gyroscope, an altimeter, a 3-axis accelerometer, and an ambient light sensor
