On the Black Bay Pro, reference time is indicated by an angular yellow Snowflake hand, 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 at 3 o’clock, is coupled with the local time hand so that when setting the time and passing midnight in retrograde, instantly jumps to the next day. A highly unusual, sophisticated, and particularly practical function for the user.

The Black Bay Pro comes with variety of straps; a black strap with a yellow band woven by traditional craftsmen, a steel bracelet inspired by the folding riveted bracelets made by TUDOR in the 1950s and 1960s, as well as a fabric-like hybrid strap in rubber and black leather with a folding clasp.
