The Black Bay Chrono Carbon 25 (Ref. M79377KN-0001) is a bold expression of Tudor’s motorsport DNA. Unveiled as a tribute to the 2025 Formula 1 season and the Visa Cash App Racing Bulls team, this 42mm chronograph pairs lightweight carbon fiber innovation with the mechanical prowess of the Manufacture Calibre MT5813. Limited to just 2,025 individually numbered pieces, it presents a fusion of performance engineering and horological finesse.
A Carbon Fibre Case Engineered for Speed
Encased in a matte black carbon fiber shell, the 42mm diameter and 14.3mm thickness provide a commanding yet ergonomic wrist presence. The fixed tachymeter bezel, also constructed in carbon fiber, reinforces the watch’s motorsport lineage, while PVD-coated titanium is used for the screw-down pushers, crown, and individually numbered case back, contributing to both durability and reduced weight.
This chronograph is fitted with integrated carbon fiber end links, completing the sleek profile, while a domed sapphire crystal enhances clarity and protection.
The Dial: Where Precision Meets Personality
A domed “racing white” dial dominates the Carbon 25’s face, punctuated by contrasting black sub-dials crafted from carbon fiber. Blue accents trace the minute and seconds tracks, subtly mirroring the Racing Bulls team livery. A vivid red depth rating adds an energetic pop at 6 o’clock, just above the discreetly placed date window.
Every detail feels deliberate—designed to evoke the high-octane world of Formula One while maintaining Tudor’s signature legibility and symmetry.
A Hybrid Strap Made for the Circuit
The timepiece is matched with a hybrid leather and rubber strap—crafted with a distinctive “tire tread” texture and bold blue stitching. This choice of materials enhances comfort and evokes the aesthetics of high-performance racing gear. Secured by a blackened pin buckle, the strap delivers both visual harmony and all-day usability.
Inside the Case: Manufacture Calibre MT5813
At the heart of the Black Bay Chrono “Carbon 25” is the COSC-certified Calibre MT5813—a high-performance automatic chronograph movement based on the Breitling B01. It features a column wheel, vertical clutch, bidirectional rotor system, and a robust 70-hour power reserve.
Operating at 28,800 vibrations per hour (4 Hz), the MT5813 ensures chronometric precision with an accuracy rating of +4/-2 seconds per day. The chronograph layout includes a central seconds hand, a 45-minute counter, and small seconds—delivering functionality with mechanical depth.

This special edition commemorates Tudor’s partnership with the Visa Cash App Racing Bulls Formula One Team and celebrates the spirit of the 2025 racing season. With only 2,025 pieces available worldwide, each watch bears a unique case-back engraving, underscoring its exclusivity and collectibility.
