The TUDOR Oyster Prince Submariner presented here and produced in 1964 featured two notable particularities. To begin with, its case had a new rounded version of crown guards. After the square or pointed shapes of the older versions of reference 7928, these new crown guards were progressively adopted by TUDOR Submariners.
Ergonomic, they would not change in appearance until the end of the 1990s. The bezel and dial of this example subsequently underwent discolouration due to intense and prolonged exposure to UV rays. Collectors use the term “Tropical” to describe this type of change, which is greatly prized.
The inscriptions on the dial of this example were silver-coloured. In accordance with the components specific to reference 7928, the case and screw-down crown of this model were signed Rolex.
Its waterproofness was guaranteed to a depth of 200 metres and it was equipped with the self-winding 390 movement.
