Diver

A diving watch, also commonly referred to as a diver's or dive watch, is a watch designed for underwater diving that features, as a minimum, a water resistance greater than 1.0 MPa (10 atm), the equivalent of 100 m (330 ft). The typical diver's watch will have a water resistance of around 200 to 300 m (660 to 980 ft), though modern technology allows the creation of diving watches that can go much deeper. A true contemporary diver's watch is in accordance with the ISO 6425 standard, which defines test standards and features for watches suitable for diving with underwater breathing apparatus in depths of 100 m (330 ft) or more. Watches conforming to ISO 6425 are marked with the word DIVER'S to distinguish ISO 6425 conformant diving watches from watches that might not be suitable for actual scuba diving.

To a large extent the diver's watch has been superseded by the personal dive computer, which provides an automatically initiated dive timer function along with real-time decompression computation and optionally other functions.

Since May 2019 Omega SA holds the record for the deepest diving watch with their Omega Seamaster Planet Ocean Ultra Deep Professional,[1] having accompanied Victor Vescovo to a depth of 10,928 meters (attached to the outside of his Deep-submergence vehicle (DSV) Limiting Factor) as part of the Five Deeps Expedition.[2]
