Xiaomi Watch S4 (41mm), Xiaomi OpenWear Stereo Pro launched globally

The Xiaomi Watch S4 (41mm) and Xiaomi OpenWear Stereo Pro, initially unveiled in China, have now been launched globally.

Starting with the watch, it has a 1.32-inch AMOLED display that peaks at 2,200 nits of brightness. It has a 5ATM water resistance rating and has an updated 4-LED + 4PD heart rate module.

This makes for more accuracy in health tracking, complemented by a modified version of Xiaomi’s Xring T1 chip. The processor now sports a modem that’s 35 percent more efficient than that of the base Xiaomi S4 watch.

Other features include real-time swim heart rate tracking and a battery life up to 8 days of use. The Xiaomi Watch S4 (41mm) starts at GBP 129 (~PHP 10K) in Mint Green.
