The Black Bay Fifty-Eight is named after the year in which the first Tudor divers’ watch, dubbed the "Big Crown" and waterproof to 200 meters (660 ft) with the reference 7924, was introduced. Among other esthetic allusions to this famous historic watch, this model has a 39-mm diameter case, in keeping with the proportions that characterize 1950s' design.
The Black Bay line is the result of the subtle blend of traditional esthetics and contemporary watchmaking. It brings together over 60 years of Tudor divers’ watches at the same time as being resolutely anchored in the present. Neo-vintage in conception, its manufacturing techniques, reliability, robustness and the quality of its finish are consistent with today’s more rigorous requirements.
