4. Maintenance
Cleaning:
Wipe the watch case and crystal with a soft, damp cloth. For the silicone strap, use mild soap and water, then rinse thoroughly and dry. Avoid harsh chemicals or abrasive materials.
Water Resistance (50 Meters / 165 Feet):
This watch is suitable for short periods of recreational swimming, but not for diving or snorkeling. Do not operate the crown or push-buttons while the watch is wet or submerged to prevent water intrusion.
Battery Replacement:
The watch is powered by a product-specific battery (included). When the watch stops running, it indicates the battery needs replacement. It is recommended to have the battery replaced by a qualified watch technician to ensure proper sealing and maintain water resistance.
5. Troubleshooting
- Watch Not Running: Check if the crown is fully pushed in. If it is, the battery may need replacement.
- Date Not Changing: Ensure the time is set correctly, especially past midnight. If the date changes at noon, it means the watch is set for AM/PM incorrectly; advance the time by 12 hours.
- Chronograph Not Resetting to Zero: This may require a chronograph reset procedure, which typically involves pulling the crown out and using the push-buttons to align the chronograph hands. Refer to a specialized watch repair guide or contact support if issues persist.
