Tudor Black Bay Fifty-Eight 79030N-0002

The Black Bay Fifty-Eight is named after the year in which the first TUDOR divers’ watch waterproof to 200 metres, the reference 7924, dubbed the “Big Crown” and was introduced. 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. It is aptly proportioned to suit slim wrists, people who like more compact watches and, of course, vintage enthusiasts. It also comes in a new colour combination – a subtle variation on the aesthetics of the Black Bay line. Evocative of a time when TUDOR divers' watches were first being made, finishing touches in gold have been applied to the hour markers, hands and minute track of the black and steel bezel. The winding crown tube is in satin-brushed steel - a new feature in the Black Bay line - in keeping with the style of the case and winding crown, which bears the TUDOR rose logo in relief. 
 

THE MANUFACTURE CALIBRE MT5402

 
In 2018, three years after the introduction of its first Manufacture Calibre, TUDOR launches a second family of movements. With its 26 mm diameter, the Calibre MT5402 displays hour, minute and second functions and has been designed for medium-sized TUDOR watches. The Calibre MT5402 has the appearance and finish typical of TUDOR Manufacture Calibres. Its openwork rotor is entirely satin-brushed and its bridges and mainplate have alternate sand-blasted surfaces and laser decorations. Its structure has been designed to ensure robustness, longevity and reliability, as has its variable inertia balance, which is maintained by a sturdy traversing bridge with a two-point fixation. Thanks to these qualities, together with its non-magnetic silicon balance spring, it is certified as a chronometer by the Swiss Official Chronometer Testing Institute (COSC). With a 70-hour power reserve, a wearer can take off the watch on a Friday evening and put it back on again on Monday morning without having to re-set and wind it.
