When the Black Bay Pro was released in 2022, it was an entirely new concept for TUDOR: take the heritage-inspired Black Bay formula and tweak it to a professional standard on the bleeding edge of tool watch functionality and design. That resulted in a robust watch featuring a 24-hour graduated satin-brushed fixed bezel and a yellow 24-hour “Snowflake” hand, all powered by the TUDOR Manufacture Calibre MT5652 with a builtin GMT function. Now the design is pushed even further, with an opaline dial that boosts legibility. The ceramic markers are outlined in black, as are the hands, to create a bold contrast that bolsters the design, making it suitable for any type of exploration, whether polar or subterranean.

On the Black Bay Pro, 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.
