Black Bay Chrono Carbon 25

The Tudor Black Bay Chrono Carbon 25 is an anniversary edition created to celebrate the 25th anniversary of Tudor’s partnership with the French Navy, the Marine Nationale. This model stands out for its forged carbon case—a first for the Black Bay line—offering a lightweight, modern take on the classic Black Bay Chrono silhouette. Limited production and the unique carbon construction have made this reference especially sought-after among collectors who appreciate both heritage and innovation.

This 41mm chronograph houses Tudor’s in-house caliber MT5813, a COSC-certified automatic movement based on the Breitling B01 architecture, prized for its column wheel and vertical clutch. The matte carbon case is paired with a stealthy black dial and contrasting white subdials, giving it a distinctly contemporary look. Water resistance is rated to 200 meters, making it suitable for daily wear and more demanding environments.

The Black Bay Chrono Carbon 25 differs from standard steel Black Bay Chronos not only in material but also in exclusivity and price. Expect premium pricing due to its limited production and commemorative status. When comparing examples, check for the original carbon-fiber-textured strap and full set, as missing accessories can impact value. This model is rarely seen on the secondary market, so condition and completeness are key drivers of desirability.
