The Tudor Heritage Black Bay Chrono brings together the aquatic heritage of the Black Bay family with the brand’s long-standing association with the racetrack. Offered in the same 41mm steel case as the other models in the Heritage Black Bay collection, it features a polished and satin finish. Other familiar hallmarks of the collection include the iconic snowflake hands, a black lacquer, high-contrast dial, and an oversized screw-down crown engraved with the Tudor rose.
At 3 o’clock there’s a 45-minute counter for the chronograph, while the sub-dial at 9 o’clock is for small seconds. The date is shown in a window at 6 o’clock, just beneath the 200m water-depth rating in red, which is a subtle nod to Tudor’s vintage dive models.
Closer inspection also reveals that the unidirectional rotating bezel, traditionally found on the Black Bay dive watches, has been replaced with a fixed bezel in circular satin-brushed steel, complete with an engraved tachymetric scale. Fluted, screw-down pushers at 2 and 4 o’clock are used to start, stop and reset the chronograph.
Inside is the Manufacture Calibre MT5813, developed and manufactured by Tudor in conjunction with Breitling. A COSC-certified chronometer, it boasts a silicon balance spring, a column-wheel chronograph mechanism with vertical clutch, and a max power reserve of 70 hours. Available on either a tan leather strap or steel bracelet with riveted links, both versions also come with a fabric strap for more casual wear.
