Introducing Tudor Unveils the Black Bay Chrono Carbon 25

Tudor continues its partnership with the Visa Cash App Racing Bulls Formula One Team into the 2025 season and unveils the Black Bay Chrono Carbon 25, a stunning chronograph inspired by the Racing Bulls' 2025 livery, featuring an ultra-light carbon fibre case.

While the case diameter remains familiar at 42mm, this new reference (79377KN) introduces a redesigned carbon fibre case that trims the thickness slightly to 14.3mm, just a touch slimmer than the standard steel model (14.4mm). The bezel is fixed and made from the same lightweight material, engraved with a tachymeter scale, and surrounds a domed sapphire crystal that protects the dial. The components are built for resilience: screw-down titanium pushers and caseback with a PVD finish, along with a PVD-coated steel crown, help maintain a robust 200m water resistance.

The racing white dial is accented with blue seconds indices, a red water resistance rating, and carbon fibre sub-dials. A date window appears at 6 o’clock, while Tudor’s signature Snowflake hands and round hour markers are outlined in black and filled with white Super-LumiNova.

Powering the watch is the Calibre MT5813, based on the Breitling B01. It’s a COSC-certified automatic chronograph equipped with a column wheel and a silicon balance spring. Beating at 28,800 vph (4Hz), it offers a power reserve of 70 hours. The watch comes fitted with a hybrid leather-rubber strap featuring a tire tread pattern and blue stitching, secured by a blackened pin buckle.

The Black Bay Chrono Carbon 25 is limited to 2,025 pieces, each individually numbered, and is priced at EUR 7,400, equivalent to AED 28,740.
