Maintenance

Cleaning

To clean your watch, wipe it with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying. Avoid using chemical cleaners, as they may damage the watch's finish or rubber components.

Battery Replacement

When the display becomes dim or the backlight function weakens, it may be time to replace the battery. Battery replacement should ideally be performed by a qualified watch technician to ensure proper sealing and water resistance. Attempting to replace the battery yourself may void any warranty and compromise the watch's integrity.

Water Resistance

This watch is designed with a degree of water resistance suitable for daily use, such as splashes or brief immersion. However, it is not suitable for swimming, diving, or prolonged exposure to water. Avoid operating buttons while the watch is wet to prevent water ingress.

Troubleshooting

Common Issues and Solutions

  • Display is blank or dim: The battery may be low or depleted. Refer to the 'Battery Replacement' section.
  • Time is incorrect: The watch may need to be reset or the time adjusted. Follow the 'Initial Time Setting' instructions.
  • Buttons are unresponsive: Ensure the watch is not wet. If the issue persists, a reset may be required (consult a technician if a simple reset doesn't work).
