Black Bay Chrono 'Carbon 25' Tortoise

The Tudor Black Bay Chronograph M79377KN-0002 debuted in 2025 as a special edition created for the Visa Cash App Racing Bulls Formula One Team at the 2025 United States Grand Prix in Austin. Produced in unique executions for drivers Liam Lawson and Isack Hadjar, the model is based on the Black Bay Chronograph “Carbon 25” and distinguished by a dial finished in a tortoise-shell pattern with gold accents, echoing the Austin-only livery of the team’s VCARB 02 cars. The watch features a 42 mm black carbon fiber case paired with a matching black bezel and crown. The dial layout retains the collection’s signature bicompax configuration with running seconds at 9 o’clock and a 45-minute totalizer at 3 o’clock. Inside ticks the self-winding MT5813, a COSC-certified chronograph movement with a column wheel and vertical clutch. It runs at 28,800 vibrations per hour and delivers a power reserve of approximately 70 hours. The Black Bay Chronograph M79377KN-0002 is fitted with a strap to match the racing-inspired theme, completing its identity as a one-off tribute to the Austin race weekend.
