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 sports chronograph for purists, with contrasting sub-counters and a high-performance automatic Manufacture Calibre, with column wheel and vertical clutch.

In 1970, TUDOR introduced its first chronograph, the Oysterdate. A watch that was both robust and functional, its unique design was characterised by its bright colours, its pentagonal hour markers shaped like a baseball home plate, its 45-minute counter and its date function at 6 o’clock. Immediately adopted by the world of motorsport, it paved the way for more than 50 years of technical chronographs that TUDOR has never stopped improving.
