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.
