Good to know

Before installation, power off the watch and discharge the old battery as much as possible. Use appropriate plastic opening tools to avoid damaging the case or display. The battery connector is small and delicate; handle with care. After replacement, charge the watch fully and perform a factory reset if needed to recalibrate the battery gauge. This battery is not user-serviceable in the sense of a quick swap; it requires disassembly of the device. Always dispose of the old battery according to local regulations.
