4. Maintenance and Care
4.1. Water Resistance
This watch is water resistant to 30 meters (100 feet). This means it can withstand splashes, rain, or brief immersion in water. It is not suitable for swimming, diving, or bathing, as prolonged exposure to water pressure or hot water can compromise its seals.
4.2. Cleaning the Watch
To clean the watch case, use a soft, damp cloth. For the elastic fabric strap, it can be hand-washed with mild soap and water, then air-dried. Avoid using harsh chemicals or abrasive materials, which can damage the watch's finish or strap.
4.3. Battery Replacement
The watch uses 1 Lithium Metal battery (included). When the display dims or functions become erratic, it may be time to replace the battery. Battery replacement should ideally be performed by a qualified watch technician to ensure water resistance is maintained.
5. Troubleshooting
- Display is blank or dim: The battery may need replacement. See Section 4.3.
- Time is incorrect: Re-set the time and date following instructions in Section 2.1. Ensure the correct 12/24-hour format and AM/PM setting.
- Indiglo light not working: Check battery level. If the battery is low, the Indiglo feature may be affected first.
- Buttons are unresponsive: Ensure the watch is not in a locked mode (if applicable, though this model typically does not have one). If issues persist, a battery replacement or professional inspection may be required.
