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 colour, of course, but also from the year 1958, when the first TUDOR divers’ watch waterproof to 200 metres was presented. Among other aesthetic nods to the historic watch, this new model offers a 39mm diameter case in keeping with the characteristic proportions of the 1950s. Ideal for those who like more compact watches and vintage enthusiasts, the Black Bay Fifty-Eight “Navy Blue” also carries on with the longtime Tudor tradition of blue sports watches.
In 1969 Tudor introduced a divers’ watch with a blue dial and bezel. Soon, the other watches in the collection were also attired in blue, creating a lasting aesthetic hallmark known as “Tudor Blue.” The Black Bay Fifty-Eight “Navy Blue” follows in this tradition with its navy blue dial and bezel inset as well as the “soft touch” straps offered with this model.
10 YEARS OF THE TUDOR FABRIC STRAP
The fabric strap is another hallmark of Tudor, woven in France on 19th Century jacquard looms by the Julien Faure company. This year marks a ten year partnership between Tudor and Julien Faure, the 150-year-old family company that has created Tudor’s artisan-made fabric straps since their introduction on the Heritage Chrono in 2010.
Blue fabric strap with silver band and buckle.
Riveted 316L steel bracelet. 
Blue soft touch with folding clasp and safety catch.
THE CALIBRE MT5402
The Manufacture Calibre MT5402, which equips the Black Bay Fifty-Eight “Navy Blue”, displays hour, minute and second functions. It has the finish typical of TUDOR Manufacture calibres. 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, as has its variable inertia balance, which is maintained by a sturdy traversing bridge with a two-point fixation. Together with its non-magnetic silicon hairspring, the Manufacture Calibre 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 Calibre 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.
