Clean the watch case and strap regularly with a soft, slightly damp cloth. Avoid using harsh chemicals, solvents, or abrasive cleaners, as these can damage the watch's finish and materials.
4.2 Battery Replacement
When the display becomes dim or functions become erratic, the battery may need replacement. Battery replacement should be performed by a qualified watch technician to ensure the watch's water resistance is maintained after the case back is opened.
