The sub-counters have a circular-grained finish and, inspired by the first generation of TUDOR chronographs, feature a 45-minute counter and a date aperture positioned at 6 o'clock. Remaining faithful to the Black Bay aesthetic, the Black Bay Chrono S&G has adopted the famous “Snowflake” hands, a brand signature for divers’ watches since 1969, to ensure outstanding readability against the domed dial.
The Manufacture Chronograph Calibre MT5813, which powers the Black Bay Chrono model, displays hour, minute, second, chronograph and date functions. Boasting a 70-hour power reserve and a silicon balance spring, the Manufacture MT5813 chronograph Calibre is certified by the Swiss Official Chronometer Testing Institute (COSC), with its performance exceeding the standards set by this independent institute. A high-performance movement, it was crafted in the purest watchmaking tradition, with a column wheel mechanism and vertical clutch. In keeping with the TUDOR philosophy of quality, it presents extraordinary robustness and reliability, guaranteed by the array of extreme tests applied to all TUDOR products.
The fabric strap is one of the hallmarks of TUDOR, which, in 2010, became one of the first watchmaking brands to offer it with its products. Woven in France using a traditional method on 19th century Jacquard looms by the Julien Faure company in the St-Etienne region, its manufacturing quality and comfort on the wrist are unique. In 2020, TUDOR celebrated ten years of collaboration with the hundred-and-fifty-year-old Julien Faure company. The partnership began with the launch of Heritage Chrono, the first model fitted with a fabric strap created by the craftsmen, at Baselworld 2010.
For the Black Bay Chrono TUDOR selected a black strap woven by these traditional craftsmen. The model is also available with a steel or steel and yellow gold bracelet inspired by the folding riveted bracelets made by TUDOR in the 1950s and 1960s. These were famous for having visible rivet heads on the side of the bracelet that held the links together. The links also had a distinct stepped construction. These two aesthetic details are found on the current bracelet, which also integrates modern manufacturing methods with solid links and laser-finished rivet-style heads. Finally, entirely in keeping with the spirit of “1970s racing”, the Black Bay Chrono offers another choice of bracelet: a bund in aged dark brown or black leather, depending on the model, with ecru topstitching and a folding clasp.
Since the launch in 1970 of the Oysterdate model, its first chronograph, TUDOR has always produced watches that are closely tied to the world of motor sport. Since 1954, TUDOR has likewise been constantly improving its professional divers’ watches. The Black Bay Chrono model combines these traditions in a sport chronograph with contrasting sub-counters and a high-performance automatic Manufacture Calibre, with column wheel and vertical clutch.
