Maintenance

2. Cleaning Your Watch

Wipe the watch case and band with a soft, dry cloth. For stubborn dirt, use a soft cloth dampened with water and a mild neutral detergent, then wipe dry. Avoid using volatile agents like thinner, gasoline, alcohol, or chemical sprays, as they may damage the watch.

3. Water Resistance

This watch is water resistant. However, it is not designed for diving or prolonged submersion. Avoid operating buttons while the watch is wet. Exposure to excessive water pressure or hot water (e.g., in showers or saunas) can compromise the water resistance seals.
