Tudor Oyster Prince Submariner
In 1954, Tudor set out on a new path which would contribute to forging its legend. It was in that year that the brand’s first divers’ watch, the Tudor Oyster Prince Submariner reference 7922, saw the light of day. Designed from its origin to fulfil exceptional criteria of durability, reliability, precision and waterproofness at a moderate price, it quickly positioned itself as an instrument of choice for professionals. Over the next 45 years this original tool-watch continuously evolved to ever better meet the specific requirements of the many types of divers who were clients of the brand. The first generation of Tudor Submariners saw numerous versions, and through them, a notable advance in terms of performance; for example, the maximum functional immersion depth, set at 100 metres initially, reached 200 metres with the introduction of reference 7924 in 1958. During this period, multiple experiments were conducted to determine which characteristics were indispensable to the ideal divers’ watch. Each reference in the 7900 series thus featured subtle specificities which, whether or not they were retained in the development of the product, contributed to its legend. Finally, with the latest variation of reference 7928, recognisable by its round crown guards, it was in the first half of the 1960s that the general lines and technical specifications that constituted the Tudor Submariner were established.
The first TUDOR divers’ watch was presented in 1954. It bore the name TUDOR Oyster Prince Submariner, reference 7922. It was a self-winding watch unique in the brand’s collection. Its features corresponded to its function as a divers’ watch: a case with a screw-down back and a crown whose waterproofness was guaranteed to a depth of 100 metres, large hour markers and hands with luminous material for easy reading in deep water, as well as a bidirectional rotatable bezel graduated in 5-minute intervals to precisely measure dive time and allow for the adjustment of the decompression stages. Its black lacquered dial, subtly domed, was designed to optimise contrast with the indications it bears – the gilt inscriptions “OYSTER PRINCE” at noon under the brand logo, and “100 m = 330 ft”, “SUBMARINER”, “ROTOR”, “SELF-WINDING” on four lines at 6 o’clock. There is also a reminder of its guaranteed waterproofness at 6 o’clock, in metres and in feet. Its Tropic-type Plexiglas crystal was dome-shaped for better water pressure resistance. Its movement was the self-winding calibre 390, developed on a Fleurier movement-blank with a frequency of 18,000 beats per hour. Finally, its 5 mm-diameter screw-down crown and its Oyster-type bracele
