Degree of Water Resistance

Degree of water resistance of CASIO watches

Water Resistance: Wearable while water is being splashed but not under any pressure.

50M Water Resistance: Wearable around sinks, during swimming, athletic sports, in shallow waters, but not while snorkeling or scuba diving.

100M Water Resistance: Wearable around sinks, during swimming, poolside diving, snorkeling, but not while jet-skiing or scuba diving.

200M Water Resistance: Wearable around sinks, during swimming, poolside diving, snorkeling, jet skiing, but not while scuba diving.

DIVER'S WATCH 200M: Wearable while scuba diving at depths not requiring helium gas.

  • ATM=Atmosphere
  • 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.
