Maintenance
Cleaning:
Wipe 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 and seals.
Water Resistance:
The watch is water resistant to 10 ATM (100 meters). This means it is suitable for recreational swimming and snorkeling. Do not operate buttons underwater. Avoid exposing the watch to hot water or steam, as this can compromise the water resistance seals.
Battery Replacement:
When the display becomes dim or functions become erratic, the battery may need replacement. Battery replacement should be performed by a qualified watch technician to ensure proper sealing and water resistance. Refer to the specifications for battery type.

Troubleshooting
- Watch display is blank or dim: The battery may be low or depleted. Replace the battery.
- Time is incorrect: Re-set the time according to the "Initial Time Setting" instructions in the Setup section.
- Buttons are unresponsive: Ensure the watch is not in a locked mode (if applicable, though not specified for this model). If issues persist, a battery replacement might resolve it.
- Water ingress: If water appears inside the watch, immediately take it to a qualified technician for inspection and repair. Do not attempt to open the watch yourself.
