Maintenance
Battery Care
The watch is powered by a button-cell battery. When the display becomes dim or functions become erratic, it is likely time to replace the battery. Battery replacement should ideally be performed by a qualified watch technician to ensure proper sealing and water resistance.
Cleaning
Clean the watch case and strap regularly with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials, as these can damage the watch's finish or plastic components.
Water Resistance
This watch is designed with a certain level of water resistance. Refer to the specifications section for details. Avoid pressing buttons underwater, as this can compromise the water seal. Do not expose the watch to hot water or steam, as this can damage the seals.
Troubleshooting
- Display is blank or dim: The battery may be low or depleted. Replace the battery.
- Buttons are unresponsive: Ensure the watch is not in a locked mode (if applicable, though this model typically does not have one). If the issue persists, the battery may be low, or there could be an internal malfunction.
- Time is incorrect: Re-set the time following the instructions in the 'Setting Time and Date' section. Check if the watch was exposed to strong magnetic fields.
- Alarm does not sound: Ensure the alarm is activated (alarm icon visible) and the alarm time is set correctly.
If problems persist after attempting these solutions, contact customer support or a qualified watch repair service.
