TUDOR pays tribute to the brand's first divers' watches with the Black Bay Fifty-Eight, a model whose dimensions evoke that of the epoch. Fitted with a TUDOR Manufacture Caliber, the Black Bay Fifty-Eight is designed for slim wrists, people who like more compact watches and vintage enthusiasts alike.
The Manufacture Calibres MT5400 and MT5402 which power the Black Bay Fifty-Eight models, display hour, minute and second functions. they show the finish typical of TUDOR Manufacture Calibres. Their builds have been designed to ensure robustness, longevity, reliability and precision, as has a variable inertia balance, which is maintained by a sturdy traversing bridge with a two-point fixation. Together with their non-magnetic silicon hairsprings, the Manufacture Calibre MT5400 and MT5402 are certified as chronometers by the Swiss Official Chronometer Testing Institute (COSC), with performances going beyond the standards set by this independent institute.
Another notable feature is that the power reserve of both these calibres is "weekend-proof"; that is to say about 70 hours, which enables the wearer to take the watch off on a Friday evening and put it back on again on Monday morning without having to reset it.
The Black Bay Fifty-Eight comes with a choice of a riveted steel bracelet with polished and satin finish, a leather or “soft touch” strap with folding clasp, or a fabric strap. One of TUDOR’s signature features, the fabric strap is made using the Jacquard technique, a traditional method achieved by a 150-year-old family business from the St-Etienne region of France.
The Black Bay Fifty-Eight gets its name from the year 1958, in which the first TUDOR divers’ watch waterproof to 200 metres (660 ft), reference 7924 or “Big Crown”, was introduced. Among other aesthetic nods to this historic watch, the model offers a case 39 mm in diameter in keeping with the characteristic proportions of the 1950s.
