Black Bay Chrono Black Carbon 25 White Dial Black Strap Watch 42mm - M79377KN-0001

From Tudor, the aesthetic codes present in the watch mirror those of the 2025 season livery on the Visa Cash App Racing Bulls Formula One Team 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. TUDOR has been tied to motorsport since the ‘50s. The Black Bay Chrono “Carbon 25”—with a case rendered entirely in carbon fiber, 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 Caliber and an aesthetic inspired by the Visa Cash App Racing Bulls Formula One Team, the Black Bay Chrono “Carbon 25” laps the competition. For a purely aesthetic touch, even the chronograph sub-counters are rendered in carbon fiber.
