TUDOR Black Bay Chrono “Carbon 25” Automatic 42mm Watch

TUDOR has been tied to motorsport since the ‘50s, competing on the open road, the racetrack, and even in the desert. The TUDOR 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.

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.
