Launched in 2025 to celebrate Tudor’s official partnership with the Visa Cash App RB Formula 1 team, the Black Bay Chrono “Carbon 25” (reference M79377KN-0001) is a strictly limited-edition chronograph of just 2,025 pieces worldwide. The “25” in the name honors the 2025 F1 season, making it one of the most motorsport-inspired pieces in Tudor’s modern catalog.

Design and Case: The Carbon Fibre Revolution

The standout feature is the entirely carbon-fibre monobloc case, measuring 42 mm in diameter with a thickness of 14.3 mm and 22 mm lug width. Unlike many “carbon” watches that only use carbon for bezels or accents, the Carbon 25 features a full carbon-fibre case, including the integrated end-links.

• Case material: Forged carbon fibre composite (extremely light and strong).
• Bezel: Fixed tachymetric scale in carbon fibre (one-piece construction) with PVD-treated titanium markers.
• Pushers & crown: PVD titanium with black DLC coating.
• Caseback: Titanium with an exhibition window showing the decorated movement.
• Crystal: Domed sapphire with anti-reflective coating.
• Water resistance: 200 m (suitable for professional diving and high-speed pursuits).

The result is a watch that weighs significantly less than its steel counterpart while maintaining structural rigidity and scratch resistance far superior to traditional metals.

Dial and Aesthetics

The dial is finished in a crisp “Racing White” with subtle carbon-fibre textured counters at 3, 6, and 9 o’clock positions, creating a technical yet elegant contrast.

• Hands: Snowflake hour and minute hands with white lume, red central chronograph seconds hand.
• Markers: Applied baton indices with generous Super-LumiNova.
• Sub-dials: 45-minute counter at 3 o’clock, small running seconds at 9 o’clock, date window at 6 o’clock.
• Additional details: Blue minute track, red accents on the chronograph registers.

The overall look is unmistakably motorsport-inspired—clean, legible, high-contrast, and purposeful.

Strap and Wearability

The Carbon 25 comes on a hybrid strap combining black rubber with a leather-effect outer layer patterned to resemble racing tire tread. The strap is secured with a blackened titanium folding clasp featuring the Tudor rose.

• Weight: Approximately 77–80 g (extremely light for a 42 mm chronograph).
• Comfort: The rubber inner layer provides excellent grip and sweat resistance; the tire-pattern texture adds visual interest without sacrificing wearability.
• Versatility: Sporty yet refined enough for casual or semi-formal settings.

Many owners note that the watch wears smaller than its 42 mm diameter suggests due to the lightweight case and integrated end-links.
