Radiomir Panerai In 1942, 720 of these diver's wristwatches - which were exceptional for the time - were produced; the complete edition was delivered to the German and Italian army which supplied its combat divers with these watches. Source: Rolex Uhren GmbH Köln Because of the 1914 invention of the luminous material "Radiomir" - a mix of zinc sulfide and radium bromide - the Panerai dials could be read well at night and in deep water. Panerai made use of this advantage in his watches and was commissioned to produce the first diver's wristwatches, called "Radiomir". The first prototypes were still produced at Rolex, the later watches and their cases were produced at Panerai according to Oyster standards. In 1936 the Panerai Radiomir became a part of the secret naval equipment. Source: "Armbanduhren Klassik Katalog", Koenigswinter 2005, page 146.
