Casio G-Shock Manufacturer's Watch WarrantyThis is a good guide to gauge water resistance
- Only watches marked with the words “DIVER’S WATCH 200M” can be worn while scuba diving (with air tanks).
- Even if a watch is water-resistant, do not operate its buttons or crown while it is submersed in water or wet. However, “DIVER’S WATCH 200M”casing models permit underwater button operation.
- After submersion in seawater, use plain water to rinse all salt and dirt from the watch.
- Even if a watch is water-resistant, avoid wearing it in the bath or in areas where detergents (soap, shampoo, etc.) are being used. Such conditions can reduce water resistance.
