4. Maintenance
4.1 Water Resistance
The watch is water-resistant up to 100 meters (330 feet). This makes it suitable for showering, swimming, and snorkeling. However, it is not recommended for scuba diving. Do not press any buttons while the watch is submerged to prevent water ingress.
4.2 Cleaning
Clean the watch with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials that could damage the case or strap.
4.3 Battery Replacement
The watch uses 1 Lithium Metal battery (included). Battery replacement should ideally be performed by a qualified watch technician to ensure water resistance is maintained. If attempting self-replacement, note that some models may feature specialized screws (e.g., triangle head screws) requiring specific tools.
