Maintenance
Cleaning
Wipe the watch regularly with a soft, dry cloth to remove dust and dirt. For stubborn stains, a slightly damp cloth can be used, followed by immediate drying. Avoid using harsh chemicals or abrasive materials, which can damage the watch's finish.
Battery Replacement
When the watch display becomes dim or stops functioning, it may be time to replace the two CR2 batteries. It is recommended to take the watch to a professional watch repair service for battery replacement to ensure the water resistance seal is properly maintained.
Storage
When not in use for extended periods, store the watch in a cool, dry place away from direct sunlight and extreme temperatures. Keep it away from strong magnetic fields to prevent interference with its timekeeping accuracy.
Troubleshooting
- Display is blank or dim: Check if the batteries need replacement. If recently replaced, ensure they are inserted correctly.
- Time is inaccurate: Re-set the time following the 'Setting Time and Date' instructions. If the issue persists, battery replacement may be necessary.
- Buttons are unresponsive: Ensure the watch is not wet. If the issue continues, there might be an internal malfunction requiring professional service.
- Water inside the watch: Immediately stop using the watch and seek professional repair. Do not attempt to dry it yourself, as this can cause further damage.
