The OPPO Watch S2 has officially launched, featuring a slim 8.9mm design. The device is available in three color options: Vibrant Orange, Misty Pink, and Mountain Gray. It includes a specialized sports strap that improves fit by 15% and reduces thickness by 19% compared to previous iterations.

A key addition is the proprietary FatMax fat-burning mode. This feature utilizes individual physiological data, such as resting heart rate and overall athletic capacity, to generate a personalized fat-burning model for the user.

The hardware includes an upgraded sensor suite featuring an ECG electrode, an 8-channel heart rate monitor, a 16-channel blood oxygen sensor, and a high-sensitivity temperature sensor.

The watch runs on the new ColorOS 17 operating system. Notable software features include a camera assistant, fluid cloud notifications, and a smart task window. Additionally, the device supports simultaneous connectivity with two smartphones.
