TUDOR has been tied to motorsport since the ‘50s. The 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. For a purely aesthetic touch, even the chronograph sub-counters are rendered in carbon fibre.

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.
