A diving watch is a watch designed for underwater diving that features, as a minimum, a water resistance greater than 10 ATM, the equivalent of 100 meters (330 ft). The typical diver's watch will have a water resistance of around 200–300 meters (660–990 feet), though modern technology allows the creation of diving watches that can go much deeper. A true diver's watch is in accordance with ISO 6425, which defines test standards and features for watches suitable for diving with underwater breathing apparatus in depths of 100 m or more. Watches conforming to ISO 6425 are marked with the word DIVER'S to distinguish diving watches from look alike watches that are not suitable for actual scuba diving.
