A diving watch is a watch designed for scuba diving which has as characteristic a waterproofing greater than ten atm , the equivalent of 100 meters . The typical diving watch has a waterproofing of about 200 or 300 meters , although modern technology allows the construction of diving watches that can go to a much greater depth 1 with a record at 12’000 meters theoretical for the Rolex Deepsea Challenge (it is actually down to 10’908 in the Mariana trench) 2 .
Modern dive watches conform to ISO 6425, which defines the standards and characteristics of watches suitable for diving with submarine breathing apparatus at depths of 100 meters or more. Watches conforming to this standard are marked DIVER’S to distinguish them from watches that would not be suitable for diving with bottles .
