Combining TUDOR’s rich diving-watch heritage with the precision of a mechanical chronograph, the Black Bay Chrono 39 introduces a bold new interpretation of the collection’s distinctive design. Affectionately nicknamed the “Bumblebee” for its striking yellow and black colour combination, this contemporary timepiece features a compact 39mm case while retaining the iconic Snowflake hands, a signature of TUDOR’s divers’ watches since 1969.

This 39mm model features a stainless steel case with polished and satin finishes, complemented by a fixed stainless steel bezel with a black anodised aluminium insert and tachymeter scale. The vibrant domed yellow dial features contrasting black chronograph sub-dials, luminescent hour markers and TUDOR’s signature Snowflake hands, ensuring excellent legibility. A date window at 6 o’clock adds everyday practicality, while a domed sapphire crystal protects the dial. The watch is presented on a three-link stainless steel bracelet with polished and satin-brushed finishes, completed by TUDOR’s T-fit rapid adjustment clasp for a comfortable and secure fit.

Powered by the COSC-certified Manufacture Calibre MT5813 self-winding mechanical chronograph movement, featuring a column-wheel mechanism, the watch offers an impressive 70-hour power reserve. Water resistance to 200 metres completes this distinctive timepiece, bringing together Swiss precision, advanced chronograph functionality and the unmistakable character of the Black Bay Chrono “Bumblebee”.
