Ever faithful to its long tradition of blue sports watches, Tudor now offers a “Navy Blue” version of its flagship model, the Black Bay Fifty-Eight.

The Black Bay Fifty-Eight “Navy Blue” gets its name from its color, of course, but also from the year 1958, in which the first Tudor divers’ watch waterproof to 200 meters (660 ft), reference 7924 or “Big Crown,” was presented. Among other aesthetic nods to this historic watch, this model offers a 39mm diameter case in keeping with the characteristic proportions of the 1950s. Ideal for slim wrists, people who like more compact watches, and vintage enthusiasts, the Black Bay Fifty-Eight “Navy Blue” also carries on with the long Tudor tradition of blue sports watches.

The Manufacture Caliber MT5402, which equips the Black Bay Fifty-Eight “Navy Blue,” displays hour, minute, and second functions. It has the finish typical of Tudor Manufacture calibers. Its rotor in tungsten monobloc is openwork and satin-brushed with sand-blasted details, and its bridges and mainplate have alternate sand-blasted, polished surfaces and laser decorations.
