Tudor’s Limited-Edition “Carbon 25” Wraps High Horology in Racing Colours

Few pursuits place more emphasis on measuring time with extreme precision than motorsports. With dreams realised or crushed within mere fractions of a second, it’s a domain in which time is everything, making it the perfect arena for Swiss maison Tudor to flex its considerable muscle. The storied watchmaker has long maintained a strong link with this high-octane world, and its latest timepiece, the new Tudor Black Bay Chrono “Carbon 25”, reinforces this connection in thrilling fashion.  

Racing into our hearts from the moment we laid eyes upon it, the Black Bay Chrono “Carbon 25” is a stunning example of Tudor’s race-ready chronograph timepieces. In fact, it further amplifies the maison’s championing of the racing spirit through its use of innovative materials, engineering, and aesthetics. From a singularly compelling exterior to the extreme accuracy of its high-performance movement, this is a watch designed for those with an unabashed need for speed. 

The Material Difference

Drawing inspiration from the Visa Cash App Racing Bulls Formula One team and its extraordinary racing machines, the Black Bay Chrono “Carbon 25” harnesses the weight-saving advantages of carbon fibre to craft a timepiece like no other. From the case and the one-piece tachymetric bezel to the end-links that affix the striking hybrid strap, this cutting-edge material is liberally deployed across the watch. Even the chronograph sub-counters are rendered in carbon fibre!

The use of this remarkable material ties in seamlessly with Tudor’s bold use of the Visa Cash App Racing Bulls Formula One car’s 2025 season livery. The combination of the domed “racing white” dial, which vividly highlights the aforementioned carbon fibre sub-counters, and the eye-catching blue of the techymeter, all wrapped within the dark finish of the 42-millimetre carbon fibre casing, make this one of the most arresting timepieces we’ve seen this year. 

Further, Tudor’s signature “snowflake” hands, which have been one of the calling cards of the maison’s dive watches since 1969, are deployed here to particularly striking effect, outlined in black with Grade A Swiss Super-LumiNova luminescent material. They sit above a dial layout that has been inspired by Tudor’s first generation of chronographs, boasting a 45-minute counter and a date aperture positioned at 6 o’clock.

A Finely Honed Racing Tool

Inside, the Calibre MT5813 accurately powers the hour, minute, second, chronograph, and date functions of the Black Bay Chrono “Carbon 25” and boasts the kind of high-level finishing one expects from Tudor movements. With an openwork rotor featuring satin-brushed with sand-blasted details, and bridges and a mainplate with alternate sand-blasted and polished surfaces with laser decorations, the internal components of this release clearly sacrifice none of Tudor’s elevated watchcraft in the pursuit of sporty performance.

In addition to its 70-hour power reserve and silicon balance spring, the movement is certified by the Official Swiss Chronometer Testing Institute (COSC). In fact, it exceeds the COSC allowance (-4/+6 seconds’ variation per day) by delivering a variation of -2/+4 seconds. This high-performance movement with its column wheel mechanism and vertical clutch has been crafted in the purest watchmaking tradition while still powering a watch that very much has its eye on motor racing’s future. 

With a five-year transferable guarantee, without registration or mandatory maintenance checks, this is a watch that can be relied upon throughout this Formula One season and many more to come. 

The Black Bay Chrono “Carbon 25” is a remarkable, limited-edition, and highly desirable timepiece. It intertwines the moment-by-moment thrill of the race track with the kind of considered approach to watchmaking that you only expect from one of the world’s finest houses of horology. 

Tudor Chronos For Any Occasion

If Tudor’s Black Bay Chrono “Carbon 25” is less traditional than you prefer your timepieces (or perhaps the team at Visa Cash App Racing Bulls Formula One are not the one that has your heart), never fear. You can still enjoy the maison’s exceptional chronograph offering thanks to the timeless styling of the Tudor Black Bay Chrono, available with either a classic white or black dial and contrasting sub-dials. 

These timepieces are a demonstration of the watchmaker’s immaculate chronograph aesthetic, boasting a slightly more compact 41-millimetre case paired with a three- or five-link stainless steel bracelet that sports polished and satin-brushed finishes with a Tudor ‘T-fit’ rapid adjustment clasp. 

Mirroring the Black Bay Chrono “Carbon 25”, these watches contain the self-winding MT5813 mechanical chronograph movement with bidirectional rotor system that offers incredibly accurate timekeeping across hour, minute, second, chronograph, and date functions. And as you would expect, the movement features the same extreme attention to detail as that contained within these watches’ carbon-constructed sibling above.

Whether you’re eager to show your support for the Visa Cash App Racing Bulls Formula One team by donning the Black Bay Chrono “Carbon 25”, or prefer something a little more classic in the form of one of these Black Bay Chrono, Tudor’s unassailable craftsmanship and attention to detail remain. Each Tudor chronograph is a potent example of motorsport precision at its very finest.
