The Black Bay Pro is 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 built-in GMT function. 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. 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.
