5. Maintenance
5.1. Cleaning Your Watch
To clean your watch, wipe it with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials, as these can damage the watch case or strap.
5.2. Water Resistance
This watch is water resistant up to 50 meters (5 ATM). This means it is suitable for showering, swimming in shallow water, and general water exposure. It is not suitable for diving, snorkeling, or high-impact water sports. Do not press any buttons while the watch is submerged in water, as this can compromise the water resistance seal.
5.3. Battery Replacement
The watch uses a CR2016 battery. 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 the water resistance seal is maintained.

6. Troubleshooting
- Watch not displaying time: Check if the battery needs replacement. If recently replaced, ensure it was installed correctly.
- Time is incorrect: Follow the 'Setting Time and Date' instructions in Section 3.2 to reset the time.
- Buttons not responding: Ensure the watch is not in a locked mode (if applicable, refer to specific model features not detailed here). If submerged, allow it to dry completely before attempting to use buttons.
- Fogging under crystal: This may indicate a breach in the water resistance seal. Avoid further water exposure and seek professional service.
