THE TUDOR BLACK BAY DARK
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 (Physical Vapour Deposition) coating. Directly derived from the thin film technology originally developed by NASA for its various space programmes, PVD or physical vapour deposition enables practically any inorganic material to be bonded with metals. The Heritage Black Bay Dark has an entirely satin finish, giving it the appearance of black military utility equipment.
The TUDOR IN-HOUSE MOVEMENT MT5602
This is a variant of the movement 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 meaning that its wearer can, for example, take off the watch on Friday evening and put it on again on Monday morning without having to wind it. 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).
