Black Bay Chrono Carbon 26 "Racing Bulls" F1 Limited Edition | Ref. 79377KN

The Story

The Tudor Black Bay Chrono Carbon 26 "Racing Bulls" (Ref. 79377KN) is an adrenaline-fueled masterpiece born on the paddocks of Formula One. Developed as an exclusive tribute to Tudor's official partnership with the Visa Cash App Racing Bulls F1 Team, this radical chronograph strips away traditional metals in favor of cutting-edge aerospace materials. Strictly limited to just 2,025 pieces globally, it breaks the boundaries of standard production models to deliver pure racing pedigree. It is a rare, high-concept conversation piece designed for the modern enthusiast who demands the elite build quality of Tudor mixed with the relentless speed of motorsport engineering.

The Craft: Carbon Fiber Architecture & High-Performance Mechanics

The architectural highlight of the Ref. 79377KN is its beautifully textured 42mm case, meticulously sculpted from an ultra-lightweight and incredibly high-tensile carbon fiber composite. This matte-black carbon weave extends seamlessly to the fixed tachymeter bezel, reducing total wrist weight while providing immense scratch resistance.

The dial presents a striking "Racing White" panda configuration, featuring deep matte-black chronograph registers, a subtle date window at 6 o'clock, and electric blue accents that perfectly mirror the official Racing Bulls team livery. Tudor’s iconic "Snowflake" hands track the time with absolute legibility against the high-contrast backdrop.

Under the hood lies the Tudor Manufacture Calibre MT5813, a heavy-duty self-winding chronograph movement developed in collaboration with Breitling. Officially certified as a COSC chronometer, this engine is equipped with a high-end column-wheel architecture and a vertical clutch system for butter-smooth pusher feedback, alongside a non-magnetic silicon balance spring. It provides an impressive 70-hour power reserve and, despite its motorsport-focused build, offers a professional-grade 200 meters (660 feet) of water resistance.

Condition & Complete Limited Edition Set

This ultra-rare timepiece is presented in pristine, Like-New condition, showing zero notable signs of wear across its carbon fiber flanks or sapphire crystal.
