#Tudor #TudorBlackBayPro #TudorGMT @TudorWatch
Black Bay Pro is an entirely new model with a dual time zone feature, a technical complication that establishes local time without losing sight of the time in another time zone. Compact, robust and sporty, this model boasts many unique aesthetic details and celebrates the spirit of the technical watches that TUDOR has produced for professionals throughout its history. Recognisable by its 24-hour graduated satin-brushed fixed bezel and its yellow 24-hour "Snowflake" hand, Black Bay Pro is powered by the TUDOR Manufacture Calibre MT5652 with built-in GMT function.

KEY POINTS
1. Satin-brushed and polished case in stainless steel, 39 mm in diameter, with a 24-hour graduated fixed bezel in stainless steel
2. Domed dial, grained matt black, with applied hour markers in monobloc luminous ceramic
3. “Snowflake” hands, a hallmark of TUDOR divers’ watches since 1969, with Grade A Swiss Super-LumiNova® luminescent material
4. Manufacture Calibre MT5652, COSC-certified with a silicon balance spring, 70-hour power reserve
5. A choice of three bracelet designs: black Jacquard fabric, hybrid rubber and leather or riveted 316L steel with TUDOR "T-fit" clasp with rapid adjustment
6. Five-year transferable guarantee with no requirement for registration or periodic maintenance checks

The Manufacture Calibre MT5652 with built-in GMT function was developed by TUDOR for the Black Bay Pro model. It illustrates the technical development process which is unique to TUDOR, drawing on adaptable architecture capable of including new functions into its manufactured movements rather than resorting to additional modules. A minor detail for some, but a must for watchmaking purists.

It 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 balance spring, the Manufacture Calibre MT5652 is certified as a chronometer by the Official Swiss 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.

Another notable feature is that the power reserve of the Manufacture Calibre MT5652 is "weekend-proof", about 70 hours. This enables the wearer to take the watch off on a Friday evening and put it back on again on Monday morning without having to reset it.

STEEL BRACELET OR JACQUARD-WOVEN OR LEATHER STRAP
The fabric strap is one of the hallmarks of TUDOR, which, in 2010, became one of the first watchmaking brands to offer it with its products. Woven in France using a traditional method 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. In 2020, TUDOR celebrated ten years of collaboration with the hundred-and-fifty-year-old Julien Faure company.

For the Black Bay Pro, TUDOR has selected a black strap with a yellow band woven by these traditional craftsmen. The model is also available with a stainless steel bracelet inspired by the folding riveted bracelets made by TUDOR in the 1950s and 1960s. Finally, the Black Bay Pro is also available with a hybrid strap in black rubber and leather with a folding clasp.
