The Black Bay Chrono “Carbon 25” continues TUDOR’s long-standing connection to motorsport, embodying its pursuit of mechanical performance. Built almost entirely from carbon fibre—including the case, bezel, end-links, and even chronograph sub-counters—it sheds every unnecessary gram for speed and precision. The Manufacture Calibre MT5813’s chronograph function with its one-piece carbon fibre tachymetric bezel deliver accurate timekeeping, while the design echoes the 2025 Visa Cash App RB Formula One Team livery.

Limited to 2,025 pieces, each watch is individually numbered on its PVD-coated titanium case back—far easier to get track time with than the car itself.
