Tudor - M79377KN-0003 Black Bay Chrono 'Carbon 26'

Tudor M79377KN-0003 description

The TUDOR Black Bay Chrono “Carbon 26” M79377KN-0003 debuted in 2025 as a limited edition tied to the 2026 Formula 1 season, building on the earlier “Carbon 25” with a revised livery-inspired color scheme and a lighter full-carbon construction. Limited to 2,026 pieces, it combines the Black Bay Chrono format with motorsport-specific materials and detailing.

Its 42mm case is made from carbon fiber and paired with a fixed carbon fiber tachymeter bezel. The pushers are rendered in PVD-finished titanium, while the case back is titanium with PVD treatment and individual numbering. Water resistance is rated to 200 meters.

The dial is domed and finished in “racing white,” with black chronograph counters rendered in carbon fiber through a layered construction. Yellow accents reference the 2026 Visa Cash App Racing Bulls livery, and the date is positioned at 6 o’clock. TUDOR’s Snowflake hands, outlined in black and filled with Grade A Swiss Super-LumiNova, preserve the Black Bay design language within a clearly motorsport-driven layout.

Inside is the Manufacture Chronograph Caliber MT5813, a self-winding chronograph with column wheel and vertical clutch architecture. It operates at 28,800 vibrations per hour, uses a silicon balance spring, and delivers a power reserve of approximately 70 hours. COSC certification is standard, and the movement is visible through the case back.

This reference is fitted on a hybrid leather-rubber strap with a tire-pattern texture and carbon fiber end-links.
