Both smart timepieces has 3D Corning Gorilla glass with optical Diamond-like Carbon (oDLC) and anti-fingerprint coating, and they are both suitable for left- or right-handed wear – thanks to the notable screen. Then again, don’t every watch is ambidextrous?
Both watches is outfitted with BioTracker 2 PPG optical sensor for 24/7 heart rate monitoring and offers abnormal heart rate warnings. The same sensor also supports OxygenBeats for blood-oxygen level.
Functionality is pretty much what you expect of a smartwatch. These includes push notifications, sleep monitor, multi sports modes etc. Other common features include water resistance to 5 ATM (50 meters or 164 feet), Bluetooth 5.0, WLAN 2.4 GHz, calls over Bluetooth, supports Alex voice assistant, and built-in speaker, microphone and linear motor for vibration.
The main differences are essentially the style (round versus rectangular) and the battery which the GTR 2 has a larger 471 mAh good for 14 days (or 38 days under “basic usage”) and the GTS 2 gets a 246 mAh battery that offers 7 days of use or 20 days under “basic usage.”
Both watches will sell for US$179.99. The Amazfit GTR 2 will be released October 30 while the Amazfit GTS 2, November 1.
