The Black Bay Fifty-Eight is named after the year in which the first Tudor divers’ watch, the reference 7924, was introduced. Waterproof up to 200 metres, it was dubbed the “Big Crown”. Among other aesthetic allusions to this famous historic watch, this model has a 39 mm diameter case, in keeping with the characteristic proportions of the 1950s.

Besides keeping with the dimensions of the watches from the 1950s, it also features characteristic angular hands known to collectors as snowflake, which appeared in the brand’s 1969 catalogue. Similar to the first-generation Tudor divers' watches, waterproof to 200m (660 ft), it is fitted with the large winding crown. These aesthetic inclusions make the watch appeal to vintage enthusiasts and is perfect for slim wrists.
Reminiscent of a time when Tudor divers' watches were first made, the Black Bay Fifty-Eight comes adorned with gold finishing to its hour markers, hands and minute track of its black and steel bezel. Equipped with the Manufacture Calibre MT5402—the second family of movements by Tudor— the watch can run for about 70 hours smoothly and reliably. This is due to the movement structure that has been designed to ensure robustness, longevity and reliability.
