Be authentic was the goal: The line of red text on the dial, highlighting the maximum guaranteed water resistance, is a rarity seen on certain 7923 references from 1955. Finally, the characteristic angular hands known as snowflake are typical of the watches delivered to the French Navy in the 1970s. It seems that the Tudor Heritage Black Bay Steel could become the long desired cult-piece by the collectors. Honestly speaking, when I saw the pictures first I was thrilled and expressed a loud WOW!
The steel bracelet of the Heritage Black Bay Steel model is inspired by the folding riveted bracelets of the Tudor watches produced in the 1950s and 1960s. These were famous for having rivet heads for attaching the links, shown on the side of the bracelet. The links also had a distinct stepped construction. These two aesthetic details are incorporated into the bracelet of the Heritage Black Bay Steel model, integrating modern manufacturing methods using solid links.
The Heritage Black Bay Steel is available in two designs, it also comes on a black aged leather strap with folding clasp.
Good to know: Both versions come with an additional khaki green fabric strap. Made using the Jacquard technique, a traditional method achieved by a hundred-year-old family business from the St-Etienne region of France.
The steel case houses the Manufacture Calibre MT5612. With a 70-hour power reserve, a wearer can take off the watch on Friday evening and put it back on again on Monday morning without having to reset and wind it. The variable inertia oscillator with silicon balance spring oscillates at a frequency of 28,800 A/h or 4Hz. This is held in place by a traversing bridge guaranteeing its robustness. Furthermore, the Calibre MT561 is certified by the Swiss Official Chronometer Testing Institute (COSC).
