In 1959, the United States Navy Experimental Diving Unit evaluated five diving watches that included the Bulova US Navy Submersible Wrist Watch, Enicar Sherpa Diver 600, Enicar Seapearl 600, Blancpain Fifty Fathoms, and the Rolex Oyster Perpetual.
The Rolex Submariner was introduced at the Basel Watch Fair in 1954 which coincided with the development of self-contained underwater breathing apparatus, known as scuba. Zodiac debuted their Sea Wolf line of waterproof watches at the 1953 Basel Fair as well.

The Fifty Fathoms was worn by Jacques Cousteau and his divers during the underwater film "Le monde du silence", which won the Palme d'or at the Cannes film festival in 1956, and in the US when TV star Lloyd Bridges wore a Blancpain Fifty Fathoms dive watch in a photo that appeared on the cover of the February 1962 edition of Skin Diver Magazine. Various models were issued by Blancpain in small quantities to the military in several countries, including US and French Navy combat diver teams. In 1953, Lip- Blancpain's Fifty Fathoms (50 fathoms = 91.44 m (300 ft)) waterproof watch was debuted at the Basel Fair. Today, interest in these watches is limited to collectors. However, these watches were made in small numbers, and were not intended for large-scale commercial distribution. In addition, a large number of "canteen" style dive watches by Hamilton, Elgin or Waltham were made to military specification during and after World War II. These watches were made by Rolex for Panerai. The vintage 1936 California Dial Radiomir Paneraiįollowing a request made by the Royal Italian Navy, in September 1935, for a luminous underwater watch for divers, Panerai offered "Radiomir" underwater timepieces in 1936.

After a series of trials undertaken by the Swiss Laboratory for Horology in Neuchâtel in May 1937, the watch was certified as being able to withstand a pressure of 1.37 MPa (13.5 atm), equivalent to a depth of 135 m (443 ft), without any water intake whatsoever. Omega SA is credited as the creator of the world's first industrially produced diving watch intended for commercial distribution, the rectangular Omega "Marine" with a patented double sliding and removable case, introduced in 1932. After more than 10 hours in the chilly water the watch remained sealed and kept good time throughout. On 7 October 1927 an English swimmer, Mercedes Gleitze attempted to cross the English Channel with a new Rolex Oyster hanging round her neck by a ribbon on this swim. In 1926, Rolex bought the patent for the “Oyster” watch case, featuring a hermetic seal.

Like their predecessors early 20th century dive watches were developed in response to meet the needs of several different but related groups: explorers, navies, and professional divers.
Early in the 20th century such watches were industrially produced for military and commercial distribution. Hard hat divers of that period sometimes placed common pocketwatches on the inside of their helmets in order to know the time spent under water.
In the 19th century water and dust resistant watches were usually one-off pieces custom made for a particular customer and described as "Explorer's Watches". The history of efforts to use watches underwater and to make watches that are water resistant, or waterproof and to make dive watches goes back to perhaps the 17th century. 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 other (optional) functions.

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. 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. 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. The round feature on the watch case side at 9 o'clock is an integrated helium release valve.Ī 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 1.1 MPa (11 atm), the equivalent of 100 m (330 ft). Breitling Avenger Seawolf, with a water resistance of 3,000 m (10,000 ft).
