TUDOR BLACK BAY 31/36/39/41 S&G

TUDOR presents a new version of its Black Bay line in steel and yellow gold with a fixed bezel. All fitted with Manufacture Calibres, the models come in four sizes, with a five-link bracelet and clasp with rapid adjustment.

The Black Bay 31, 36, 39 and 41 S&G models bring a unique aesthetic to the Black Bay line. Their curved cases, highlighted with polished yellow gold sections, offer a language that departs slightly from the brand’s iconic tool watch spirit to embrace a sophisticated, versatile, unisex chic.

Fitted with Manufacture Calibres, including reference MT5201 which ushers in a new family of TUDOR movements, these models are at the cutting edge of technical watchmaking refinement. Another important feature for optimum comfort is the five-link bracelet which comes with the TUDOR “T-fit” clasp, with rapid adjustment, in all sizes.

TUDOR BLACK BAY S&G

Available in black and silver dial versions, they come with “Snowflake” hands, a hallmark of TUDOR divers’ watches introduced in 1969, with Grade A Swiss Super-LumiNova® luminescent material.

The case of the Black Bay 31, 36, 39 and 41 S&G models presents a sophisticated, curved vision of the famous Black Bay aesthetic. With its polished and domed sides in all available sizes, its soft silhouette is accentuated by a new curved winding crown.

In addition to the seductive curves, the polished yellow gold of the bezel and crown is new to the Black Bay line, as the precious metals used to date have been exclusively satin-brushed for a matt finish. There is also the option of a diamond-set bezel for sizes 31, 36 and 39.

With the introduction of the Manufacture Calibre MT5201, TUDOR now offers three families of self-winding movement – large (MT56), medium (MT54) and small (MT52). Manufacture Calibre MT5201 was specifically developed to power watches with smaller dimensions.

TUDOR Manufacture Calibres have been designed to ensure robustness, longevity, reliability and precision, as has the variable inertia balance, which is maintained by a sturdy traversing bridge with a two-point fixation.

Together with their non-magnetic silicon balance spring, they are certified as a chronometer by the Official Swiss Chronometer Testing Institute (COSC), with its performance going beyond the standards set by this independent institute.

The power reserve of the large and medium-sized TUDOR Manufacture Calibres is about 70 hours. For the Manufacture Calibre MT5201, the power reserve is approximately 50 hours.

All Black Bay 31, 36, 39 and 41 S&G models are available on a five-link bracelet in 316L steel and yellow gold. It comes complete with a robust clasp in 316L steel with TUDOR “T-fit” rapid adjustment system for the length. Easy to use, requiring no tools and offering five positions, this practical system allows the wearer to carry out a fine, instant adjustment of up to 8mm on the clasp.
