A steel divers’ watch entirely in black steel fitted with a mechanical movement, developed, manufactured and assembled in-house by TUDOR, the Heritage Black Bay Dark model is a new addition to the Heritage Black Bay family.
The characteristic elements of the Heritage Black Bay Dark’s personality have been drawn from TUDOR’s history. It inherits the general lines, as well as the domed dial and crystal from the first TUDOR diving watches. It features the particularly prominent winding crown from the famous 7924 reference of 1958, known as the Big Crown. It borrows the characteristic angular hands, known as snowflake, from the watches delivered in large quantities to the French National Navy in the 1970s. The indication of guaranteed water depth engraved in red on the dial, and the red triangle on the rotatable bezel can both be added to the list of important historic design features that reappear in this new model.
The characteristic features of the Heritage Black Bay Dark model centre on the 41 mm wide steel case, finished with a black PVD-treated coating. The Heritage Black Bay Dark has an entirely satin finish, giving it the appearance of black military utility equipment.
The in-house movement MT5602 was manufactured by TUDOR and developed for the Heritage Black Bay model. It displays hours, minutes and seconds, and bears the reference MT5602, in which “MT” stands for “Mouvement TUDOR”. In 2015, TUDOR announced the first mechanical movement in its history to have been developed, manufactured and assembled in-house.
A high-performance calibre of excellent precision and proven robustness, it offers a 70-hour power reserve. Beating to a frequency of 28,800 beats/hour or 4Hz, the movement is regulated by a variable inertia oscillator with silicon balance spring, held in place by a traversing bridge – a guarantee of its robustness. Furthermore, the movement is certified by the Swiss Official Chronometer Testing Institute (COSC).
With a choice of black PVD-treated steel bracelet or an aged leather strap with a black PVD-treated steel folding clasp, each Heritage Black Bay Dark model is also supplied with an extra grey fabric strap. Made in the Jacquard technique according to traditional methods by a hundred-year-old family business from the St-Etienne region of France, this strap is a signature feature of TUDOR’s Heritage line.
