TUDOR presents a new technical model with a whole new aesthetic. Named Black Bay Pro, it has a 39-millimetre diameter, a fixed steel bezel and a Manufacture Calibre with built-in GMT function.

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.
