BLACK BAY 31/36/39/41

Tudor presents a new version of its Black Bay line in steel 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 31/36/39/41 models bring a unique aesthetic to the Black Bay line. The curved cases feature a combination of finishes that elevates the watch in a contemporary fashion and offers a design language that slightly departs from the brand’s iconic tool watch spirit to embrace a sophisticated, versatile, unisex chic look and feel.

Fitted with Manufacture Calibres 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.

New for this year is an array of sunray dials that further push the watch in a stylish direction. Depending on whether the dial is blue, anthracite, or light champagne-coloured, the minute track is rendered in a contrasting colour that evokes a certain warmth to the design.

A case made of curves and sparkles

The case of the Black Bay 31/36/39/41 models presents a sophisticated, curved vision of the famous Black Bay aesthetic.

New curved winding crown

With its polished and domed sides in all available sizes, its soft silhouette is accentuated by a new curved winding crown.

Polished bezel and crown

In addition to the seductive curves, the polished bezel and crown is carried over from the S&G models debuted last year.


TUDOR offers three families of self-winding movement, all used in the various sizes of the Black Bay 31/36/39/41 models - large (MT56), medium (MT54) and small (MT52).
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.

Another notable feature is that the power reserve of the large and medium-sized TUDOR Manufacture Calibres 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. For the Manufacture Calibre MT5201 (family of small movements), the power reserve is approximately 50 hours.


The Black Bay line features dials inspired by the TUDOR divers’ watches produced during the 1950s. It borrows the characteristic angular hands known to collectors as “Snowflake” from models that appeared in the brand’s 1969 catalogue. Its unprotected crown and the characteristics of its case are reminiscent of the first generations of TUDOR divers' watches.

The Black Bay line is the result of the subtle blend of traditional aesthetics and contemporary watchmaking. Far from simply being an identical re-release of a classic, it brings together over sixty years of TUDOR dive watches, whilst at the same time being resolutely anchored in the present.

It is neo-vintage in conception, yet its manufacturing techniques, reliability, robustness and the quality of its finish are consistent with today's more rigorous requirements.


Every TUDOR watch, including the Black Bay, is assembled and fully tested to TUDOR’s superior standards at the new TUDOR Manufacture located in the Le Locle, Switzerland.

This new state-of-the-art facility, bringing together the know-how of watchmakers with the best in production management and automated testing systems, was completed in 2021 after three years of construction. All decked out in TUDOR red, the Manufacture spans over four levels totaling more than 5,500 square meters and is physically and visually connected to the neighboring Kenissi Manufacture, the TUDOR movement production facility founded in 2016.

With Kenissi and a network of TUDOR-owned affiliates, the brand has been able to integrate the development and production of high-performance mechanical calibers. As a consequence, TUDOR now fully masters the manufacturing of strategic components and can guarantee their quality.


Since the brand’s creation by Hans Wilsdorf in 1926, and in line with his vision of the ideal timepiece, TUDOR has been ceaselessly creating watches that are as robust, durable, reliable and precise as possible. On the strength of this experience, and confident in the superior quality of its watches, TUDOR offers a five-year guarantee for all its products. This guarantee does not require the watch to be registered or submitted to periodic checks and is transferable. TUDOR also recommends that its watches should be serviced approximately every ten years depending on the model and the extent of its use on a day-to-day basis.


TUDOR is an award-winning Swiss-made watch brand, offering mechanical watches with sophisticated style, proven reliability and unmatched value for money. The origins of TUDOR date back to 1926, when “The Tudor” was first registered as a brand on behalf of the founder of Rolex, Hans Wilsdorf. He officially set up the Montres TUDOR SA company in 1946 to produce watches that respect the traditional Rolex philosophy of quality at a more affordable price point. Throughout their history, thanks to their robustness and affordability, TUDOR watches have been chosen by some of the boldest adventurers, on land, in the air, underwater and on ice. Today, the TUDOR collection includes iconic lines such as Black Bay, Pelagos, 1926 and Royal. Since 2015, TUDOR has also offered models with mechanical Manufacture Calibres with multiple functions and superior performance.


In 2017, TUDOR launched a new campaign with the #BornToDare signature. It reflects both the history of the brand and what it stands for today. It tells the adventures of individuals who have achieved the extraordinary on land, on ice, in the air or underwater, with a TUDOR watch on their wrists. It also refers to the vision of Hans Wilsdorf, the founder of TUDOR, who manufactured TUDOR watches to withstand the most extreme conditions, watches made for the most daring lifestyles. It is testimony to TUDOR's singular approach to watchmaking, which has made it what it is today. At the cutting edge of the watchmaking industry, its innovations are now essential benchmarks. The TUDOR #BornToDare spirit is supported throughout the world by first class ambassadors, whose life achievements result directly from a daring approach to life.
