Maintenance and Care

- Cleaning: Wipe the watch case and band regularly with a soft, damp cloth. For stubborn dirt, use a mild soap solution and rinse thoroughly, then dry.
- Battery Replacement: When the display becomes dim or the watch stops functioning, the battery may need replacement. It is recommended to have the battery replaced by a qualified watch technician to ensure proper sealing and water resistance. The watch uses 1 AAA battery.
- Storage: Store your watch in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
- Shock Resistance: While designed to be shock-resistant, avoid unnecessary impacts or dropping the watch to prevent damage.
