In 1967, Tudor began development of a new watch for the American government and this resulted in the production of prototypes, as well as a patent for a hitherto unseen function. The Tudor Black Bay P01 model (which stands for prototype 1) is inspired by a prototype developed as part of this study and kept in the brand’s archives, only to have its unique aesthetic brought to life in 2019.

Equipped with the Manufacture Calibre MT5612, the Black Bay P01 model displays the hours, minutes, seconds and date. Together with a non-magnetic silicon balance spring and a 70-hour power reserve, the Calibre MT5612 is certified as a chronometer by the Official Swiss Chronometer Testing Institute. Its accompanying strap is a rubber base with “snowflake” motif on its back, finished with a brown leather trim. For its innovative spirit, the watch was awarded the ?Challenge? Prize at the 2019 Grand Prix d’ Horlogerie de Gen?ve.
