The Tudor Black Bay Chrono Carbon 25, reference 79377KN-0001, is a specialized 42mm luxury sports watch developed in partnership with the VCARB Formula One team. This model features a lightweight case and fixed tachymeter bezel constructed from a black carbon fiber composite, complemented by black PVD-treated titanium for the screw-down crown, pushers, and caseback. The matte white racing dial is accented by blue sub-dials and a red-tipped seconds hand, maintaining the signature snowflake hands and luminescent hour markers typical of the Black Bay line. It is powered by the COSC-certified manufacture caliber MT5813, an automatic chronograph movement with a column wheel and vertical clutch, offering a robust 70-hour power reserve.
The watch includes a date function positioned at the 6 o’clock mark and a 45-minute chronograph counter at 3 o’clock, alongside a small seconds sub-dial at 9 o’clock. Despite its focus on motorsport aesthetics and materials, the timepiece retains the collection’s diving heritage with a water resistance rating of 200 meters. It is presented on a hybrid leather and rubber strap with a folding clasp.
General reviews highlight the Carbon 25 as a significant departure from Tudor’s traditional steel builds, often praising its surprising lightness and the high-contrast legibility of the white and black color scheme. While some enthusiasts note the watch’s 14.4mm thickness, many find that the dark carbon material and reduced weight make it wear more comfortably and appear sleeker than its stainless steel counterparts. Critics generally laud the value provided by the MT5813 movement, though some find the racing-themed livery more niche than the standard Black Bay Chrono models.
