The T-Rex Dual Solar is also designed to be particularly rugged, with a titanium bezel, sapphire glass, and a case water-resistant to 10 ATM. The 1.32-inch AMOLED display achieves an impressive brightness of 3,000 nits and a resolution of 466 x 466 pixels. In addition to a heart rate and SpO2 sensor, Amazfit includes a skin temperature sensor, but omits an ECG.
An NFC chip for contactless payments comes as standard, as do a speaker, microphones, and a GPS module. With Amazfit LiveShare, the smartwatch can share the wearer's location, distance traveled, pace, and current heart rate with selected friends, so they can see if problems arise.
