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. 

Its build has been designed to ensure robustness, longevity, reliability, and precision. Its variable inertia balance is maintained by a sturdy traversing bridge with a two-point fixation. Together with its non-magnetic silicon hairspring, the Manufacture Caliber MT5402 is chronometer-certified by the Swiss Official Chronometer Testing Institute (COSC), with its performance going beyond the standards set by this independent institute. In fact, where COSC allows for an average variation in the daily running rate of a watch movement of between -4 and 6 seconds in relation to absolute time, Tudor applies a tolerance of between -2- and 4-seconds’ variation in its daily rate on the watch fully assembled. 

Another notable feature is that the power reserve of the Manufacture MT5402 Caliber 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 wind and reset it.
