caption_attribution_description: Panerai "Radiomir" underwater timepiece with a California dail. This watch was created in 1936 for the 1st Submersible Group. It was developed in response to the request made by the Royal Italian Navy (Marina Militare) in September 1935 for a luminous underwater watch for divers. A California dial refers to a clock face that consists of half Roman (usually 10 o'clock to 2 o'clock) and half Arabic numerals (usually 4 o'clock to 8 o'clock). Sometimes the hours of 3, 6, and 9 are replaced with a dash instead of a numeral and an inverted triangle in place of the 12. The use of this dial style dates back to the 1930s, for example in early Rolexes, Marina Militare and Kampfschwimmer diver's watches.
context_page_description: In watch-making, or horology, a California dial refers to a clock face that consists of half Roman and half Arabic numerals. Sometimes the hours of 3, 6, and 9 are replaced with a dash instead of a numeral and an inverted triangle in place of the 12. The use of this dial style dates back to the 1930s, for example in early Rolexes, Panerai, Glycine watch and Kampfschwimmer diver's watches. A number of Rolexes were refurbished by a company based in California using this style of dial, resulting in the name "California dial".
  A modern example of a watch with a California dial is Nomos Glashütte's "Club Campus".
