TUDOR has been tied to motorsport since the ‘50s, competing on the open road, the racetrack, and even in the desert. The new Black Bay Chrono “Carbon 25”—with a case rendered entirely in carbon fibre, including the end-links, with titanium pushers—marks a long history of TUDOR going wheel-to-wheel with racing teams. With a tech-forward, redesigned lightweight case, column wheel Manufacture Calibre and an aesthetic inspired by the Visa Cash App Racing Bulls Formula One Team, the Black Bay Chrono “Carbon 25” laps the competition.
Motorsports are inherently dangerous. High-speed driving requires drivers to operate at the very edge of the performance—and safety—envelope. Time is at the centre of all forms of competitive driving. It’s what separates winners from losers. Champions are made and lost in fractions of a second. TUDOR knows a thing or two about how important time is to the best drivers in the world. Way back in the late ‘60s when TUDOR was campaigning a cutting-edge Porsche 906 in Japan, the drivers wore TUDOR watches on their wrists.
In 2025, TUDOR continues to keep performance drivers on time. Just ask Visa Cash App Racing Bulls Formula One Team drivers Liam Lawson and Isack Hadjar.
The new Black Bay Chrono “Carbon 25” continues the long tradition of TUDOR’s presence on the track. This new watch represents TUDOR’s relentless pursuit of mechanical performance. Carbon fibre is the ideal material for a racing chronograph because of its weight-saving advantages. Less weight equals more speed, and that speed can be accurately measured using Manufacture Calibre MT5813’s chronograph function in conjunction with the one-piece tachymetric bezel, which is also fashioned out of lightweight carbon fibre. Even the end-links that affix the hybrid strap to the case are rendered in carbon fibre—every little bit of weight shed counts. For a purely aesthetic touch, even the chronograph sub-counters are rendered in carbon fibre.
The aesthetic codes present in the watch mirror those of the 2025 season livery on the Visa Cash App Racing Bulls Formula One car. Only 2,025 Black Bay Chronograph “Carbon 25” examples will be made, paying homage to this important year in TUDOR’s ever-evolving motorsport history. On the PVD-finished titanium case back, the individual number of the watch is identified. That means it’s a whole lot easier to get some “seat time” with the watch than it is with the car.
THE SPIRIT OF ASPHALT AND SEA
Remaining faithful to the Black Bay aesthetic, the Black Bay Chrono model has made the famous “Snowflake” hands – a brand signature for divers’ watches since 1969 – its own, in a version honed to ensure optimum readability on its domed “racing white” dial with two hollowed black sub-counters. Inspired by the first generation of TUDOR chronographs, the dial layout includes a 45-minute counter and a date aperture positioned at 6 o'clock. The recognisable characteristics of the Black Bay line – bevelled lugs and TUDOR rose-signed crown – are preserved in a carbon fibre case with a 42-millimetre diameter. Typical of the scrupulous attention to detail that is characteristic of the brand, the design of the titanium pushers has been inspired by the very first generation of TUDOR chronographs. A fixed bezel in carbon fibre with a tachymetric scale completes the look and function of these sporty chronographs.
THE MANUFACTURE CHRONOGRAPH CALIBRE MT5813
The Manufacture Chronograph Calibre MT5813, which powers the Black Bay Chrono model, displays hour, minute, second, chronograph and date 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 and polished surfaces with laser decorations.
Boasting a 70-hour power reserve and a silicon balance spring, the Manufacture MT5813 Chronograph Calibre is certified by the Official Swiss Chronometer Testing Institute (COSC), with its performance exceeding the standards set by this independent institute. In fact, where COSC allows an average variation in the daily rate of an uncased movement of between -4/+6 seconds’ variation per day, TUDOR applies a -2/+4 seconds’ variation standard on the completely assembled watch. A high-performance movement, it was crafted in the purest watchmaking tradition, with a column wheel mechanism and vertical clutch. In keeping with the TUDOR philosophy of quality, it presents extraordinary robustness and reliability, guaranteed by the array of extreme tests applied to all TUDOR products.
Derived from the Chronograph Manufacture Calibre B01 from Breitling, with a high-precision regulating organ developed by TUDOR and exclusive finishes, this movement is the result of a lasting collaboration between the two brands, which have chosen to pool their expertise in the design and production of certain mechanical movements.
THE ESSENCE OF BLACK BAY
Like other models in the Black Bay range, the Black Bay Chrono has adopted TUDOR's characteristic angular hands known as “Snowflake” that first appeared in the brand’s 1969 catalogue. The result of a subtle blend of traditional aesthetics and contemporary watchmaking, the Black Bay line is far from simply being an identical rerelease of a classic. Resolutely anchored in the present, it brings together over 70 years of TUDOR divers' watches. Whilst it is neo-vintage in conception, its manufacturing techniques and its robustness, reliability, durability and precision as well as the quality of its finish are above modern industry standards.
5 DECADES OF TUDOR CHRONOGRAPHS
In 1970, TUDOR introduced its first chronograph, the Oysterdate. A watch that was both robust and functional, its unique design was characterised by its bright colours, its pentagonal hour markers shaped like a baseball home plate, its 45-minute counter and its date function at 6 o'clock. Immediately adopted by the world of motorsport, it paved the way for more than 50 years of technical chronographs that TUDOR has never stopped improving.
THE TUDOR MANUFACTURE
Every TUDOR watch is assembled and fully tested to TUDOR’s superior standards at the new TUDOR Manufacture located in 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 totalling 5,500 square meters and is physically and visually connected to the neighbouring 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 calibres. As a consequence, TUDOR now fully masters the manufacturing of strategic components and can guarantee their quality.
THE TUDOR GUARANTEE
Since its creation by Hans Wilsdorf in 1926, and in line with his vision of an ideal watchmaking product, TUDOR has never stopped producing the most robust, durable, reliable and precise watches in existence today. Bolstered by this experience, and confident in the knowledge of the superior quality of its watches, TUDOR offers a five-year guarantee on all its products. This guarantee does not require the watch to be registered or any periodic maintenance checks to be performed and is transferable should the watch change ownership during coverage. TUDOR also recommends that its watches should be serviced approximately every 10 years depending on the model and the extent of its use on a day-to-day basis.
