Maintenance

Water Resistance

This watch is water-resistant to 330 feet (100 meters). This means it is suitable for showering, swimming, and snorkeling. Do not press any buttons while the watch is submerged in water, as this can compromise the water seal.

Battery Replacement

The watch uses one LR44 battery (included). When the display dims or functions become erratic, it may be time to replace the battery. Battery replacement should ideally be performed by a qualified watch technician to ensure proper sealing and maintain water resistance.

Troubleshooting

  • Display is blank or dim: The battery may be low or depleted. Replace the LR44 battery.
  • Time is incorrect: Re-enter the time setting mode and adjust the time, date, and year as described in the "Setup and Time Setting" section.
  • Buttons are unresponsive: Ensure the watch is not in a locked mode (if applicable, though not a stated feature for this model). If the issue persists, a battery replacement might be necessary, or contact support.
  • Water inside the watch: Immediately take the watch to a professional watch repair service. Do not attempt to open it yourself, as this will void the warranty and further damage the watch.
