On the Black Bay GMT, the reference time is indicated by an angular "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 connected to the local time hand so that when setting the time and passing midnight in retrograde, it instantly jumps to the previous day. A very practical and technical detail for the user. The 24-hour graduated bidirectional rotating bezel and "24-hour" hand mean you can also keep track of a third time zone. On the anodised aluminium disc of the S&G models, the graduations for the twelve daylight hours are gold-coloured on the brown section with the night-time hours on the black section.
