6.1 Cleaning Your Watch
Wipe the watch case and strap regularly with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by drying thoroughly. Avoid using harsh chemicals or abrasive materials.

The watch is powered by a nonstandard battery (included). When the display becomes dim or functions become erratic, it may be time for a battery replacement. It is recommended to have the battery replaced by a qualified watch technician to ensure water resistance integrity is maintained.
