Throughout their history, TUDOR watches have been chosen by some of the boldest adventurers, like the 30 explorers who embarked on the two-year British North Greenland Expedition to study Arctic ice exactly 70 years ago, with TUDOR watches on their wrists. Brand founder Hans Wilsdorf supplied watches for the members of the expedition. He had just created the first waterproof and self-winding TUDOR watch, the Oyster Prince model, and couldn't imagine a better environment for testing it than the extreme climate of the Arctic. The Black Bay Pro model reflects the heritage of those instruments used by the pioneering explorers. This is a tool-watch designed for professional use.
On the Black Bay Pro model, the reference time is indicated by an angular yellow "Snowflake" hand, an aesthetic hallmark of TUDOR, which completes a lap of the dial every 24 hours. Local time is indicated by another, shorter "Snowflake" hand set by a jumping hour, which can be moved either backwards or forwards. The date, displayed through an aperture positioned at 3 o'clock, is coupled with the local time hand so that when setting the time and passing midnight in retrograde, it instantly jumps to the previous day. A highly unusual, sophisticated, and particularly practical function for the user.
The Manufacture Calibre MT5652 with built-in GMT function was developed by TUDOR for the Black Bay Pro model. It illustrates the technical development process, which is unique to TUDOR, drawing on adaptable architecture capable of including functions into its manufactured movements rather than resorting to additional modules. A minor detail for some, but a must for watchmaking purists.
The power reserve of the Manufacture Calibre MT5652 is "weekend-proof", about 70 hours. This enables the wearer to take the watch off on a Friday evening and put it back on again on Monday morning without having to reset it.
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.
For the Black Bay Pro, TUDOR has selected a black strap with a yellow band woven by these traditional craftsmen. The model is also available with a steel 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, the Black Bay Pro is also available with a fabric-like hybrid strap in rubber and black leather with a folding clasp.
Whilst this model is part of the Black Bay line, it introduces many unique aesthetic details, starting with its winding crown which has been designed for maximum grip. Reminiscent of the curves found on the crowns of the brand's historical technical watches, this component is set flush to the middle case band so that its tube is not visible. In another feature, the applied hour markers on the dial are made from monobloc luminous ceramic. This feature enhances the technical aesthetic of Black Bay Pro whilst considerably increasing the luminous surface of the hour markers.
A bracelet clasp, with a TUDOR "T-fit" rapid size-adjustment system, completes the list of new innovations included in this model. Easy to use, requiring no tools and offering five positions, the "T-fit" system allows the wearer to carry out a fine, instant adjustment of up to 8mm on the clasp.
