Maintenance and Care

1. Cleaning Your Watch

  • Wipe the watch case and strap with a soft, damp cloth.
  • For stubborn dirt, use a mild soap solution and rinse thoroughly with clean water.
  • Avoid using harsh chemicals or abrasive cleaners, as these can damage the watch's finish or seals.

2. Water Resistance

This watch is water resistant up to 100 meters (330 feet). 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 resistance seals.

3. Battery Replacement

The watch uses one Lithium Metal battery (CR2016). When the display dims or functions become erratic, the battery may need replacement. It is recommended to have the battery replaced by a qualified watch technician to ensure proper sealing and maintain water resistance. Attempting to replace the battery yourself may void the warranty and compromise water resistance.
