Water Resistance of Casio
*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 area where detergents (soap, shampoo, etc.) are being used. Such conditions can reduce water resistance.
