Built for the Track, Inspired by the Bulls
TUDOR’s motorsport roots run deep. In the late 1960s, their watches were worn by drivers racing Porsche 906s in Japan. That spirit of timing under pressure is still alive today in their partnership with the Visa Cash App Racing Bulls Formula One team. The new Black Bay Chrono Carbon 25 is a product of that legacy, and it wears its motorsport DNA with confidence.
The watch’s design language is drawn directly from the 2025 Racing Bulls livery. The 42-millimetre case is crafted entirely from carbon fibre, including the end-links that secure the hybrid strap. The fixed tachymetric bezel is also a single piece of carbon fibre, built for function as much as for aesthetics. Even the chronograph sub-counters are made from carbon fibre, a rare detail that speaks to TUDOR’s focus on authenticity.
Limited to just 2,025 pieces, each individually numbered on a titanium case back finished with black PVD. That makes it far more accessible than a Formula One seat, yet no less engineered.
An Engine Worthy of the Badge
Inside the Carbon 25 beats the Manufacture Calibre MT5813. Developed in partnership with Breitling and based on the Chronograph Calibre B01, it’s been refined by TUDOR to meet stricter tolerances and deliver long-haul reliability.
It is a self-winding chronograph movement with a bidirectional rotor system, a silicon balance spring, and a column wheel mechanism with a vertical clutch. The movement delivers approximately 70 hours of power reserve. Precision is no afterthought. COSC certification ensures a variation of -4 to +6 seconds per day, but TUDOR goes further by regulating the assembled watch to a tighter range of -2 to +4.
The movement’s finishing includes an openwork tungsten monobloc rotor with sand-blasted and satin-brushed surfaces. Laser-decorated bridges and a robust 28,800 vph frequency complete the technical profile.
Details that Matter
The dial is domed and finished in what TUDOR calls “racing white,” a soft matte tone that offers strong contrast against the carbon fibre sub-dials. At three o’clock sits the 45-minute chronograph counter. Small seconds are positioned at nine, and the date aperture rests cleanly at six. Every element is considered for both symmetry and legibility.
TUDOR’s signature Snowflake hands, first introduced in 1969, are rendered here in black with Grade A Swiss Super-LumiNova for high visibility in low light. The hands, hour markers, and subtle detailing reflect TUDOR’s blend of traditional craftsmanship with modern utility.
The strap is a hybrid of leather and rubber, textured like a performance tire. Its end-links are carbon fibre, keeping the weight down and the integration sharp. A domed sapphire crystal covers the dial, and the case is water-resistant to 200 metres, making it one of the more durable chronographs in this weight class.
From Asphalt to Wrist
Some watches nod to racing. This one drives the idea home. Every gram removed, every surface treated, every complication added serves the larger goal of performance. The Carbon 25 is less a watch inspired by motorsport and more a technical instrument built with racing in mind.
For those who understand timing as more than a display on a dial, for collectors who appreciate mechanical honesty, and for fans who find beauty in purpose-built design, this release offers something real. It brings decades of TUDOR’s watchmaking and motorsport experience to a sharp point.
Not every chronograph earns the right to sit at the intersection of pit lane and wrist. This one does.
