Tudor: Black Bay Fifty-Eight 925 Silver

Tudor presents a new version of its popular Black Bay Fifty-Eight model in 925 silver with an open case back – two firsts for a Tudor divers’ watch.

The name of the Black Bay Fifty-Eight 925 model is, of course, a reference to the precious metal of its case, but also to 1958, the year in which the first TUDOR divers’ watch waterproof to 200 metres, reference 7924 or “Big Crown”, was introduced. Among other aesthetic nods to this historic watch, this model offers a case 39 mm in diameter in keeping with the characteristic proportions of the 1950s. 

THE 925 SILVER

The use of 925 silver is a first for a Tudor divers’ watch, and the composition of the chosen alloy is a secret that the brand keeps close to its chest. The properties of this alloy are such that use does not affect the appearance of the case of the Black Bay Fifty-Eight 925. Entirely satin-finished for a matt effect, it possesses an unexpected incandescent brilliance. 

The silver case of the Black Bay Fifty-Eight 925 is also accentuated by its dial, which is taupe in colour, and its matching bezel insert. Numerous silver details add the finishing touches to this model’s delicate face, especially the famous “Snowflake” hands, one of Tudor’s hallmarks since 1969, as do the graduations and text. The same colour palette is found on the fabric strap offered with this model. Woven in France on 19th century Jacquard looms by the Julien Faure company in the St-Etienne region, its manufacturing quality and comfort on the wrist are unique. 

THE MANUFACTURE CALIBRE MT5400

The Manufacture Calibre MT5400, which powers the Black Bay Fifty- Eight 925, 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 a variable inertia balance, which is maintained by a sturdy traversing bridge with a two-point fixation. Together with its non-magnetic silicon hairspring, the in-house Calibre MT5400 is certified as a chronometer 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 an average variation in the daily running of a watch of between -4 and +6 seconds in relation to absolute time in a single movement, TUDOR insists on between -2 and +4 seconds’ variation in its running when it is completely assembled. 

Certain of the quality of its watches, Tudor offers a five-year guarantee and recommends servicing after approximately 10 years from the date of purchase. An incredible value for money for a watch priced at €. 4.050.
