  • Rotatable bezel

    The rotatable bezel displays the time indicated by the 24-hour hand. It can be turned to 48 positions in either direction.

  • Date Window

    Displays the current date.

  • Winding crown

    The winding crown is used to set the time and date and to wind the watch if it has not been worn. The winding crown is screwed down onto the case to ensure water resistance. It must be fully tightened after each manipulation.

  • 24-hour hand

    This hand corresponds to the reference time. 24-hour hand moves around the dial once every 24 hours. According to the position of the bezel, this hand displays a second or a third time zone.

  • Seconds hand

    The seconds hand can be adjusted via the winding crown or left unchanged when setting the time to different time zones.

  • Hour hand

    This hand corresponds to local time. This hand moves around the dial once every 12 hours.

  • Minute hand

    The minute hand can be adjusted via the winding crown or left unchanged when setting the time to different time zones.

  • Reference time

    The reference time is your “home” or “main” time zone. During a journey, the reference time is indicated by the trianguler tipped 24 hour hand. Setting the reference time also moves the conventional hour hand (local time). For this reason, the reference time must be set before setting the local time.

DESIGNED TO WITHSTAND THE ELEMENTS

The Black Bay GMT features a 41 mm satin-brushed steel case, waterproof to 200 metres (660 ft). Luminescent hour markers set against the black dial ensure legibility at night-time — and in all conditions. The dial features a GMT mention at 6 o’clock.

  • The Manufacture Calibre MT5652 with built-in GMT function was developed by TUDOR for the Black Bay Pro model. It illustrates the technical development process, which is unique to TUDOR, drawing on adaptable architecture capable of including functions into its manufactured movements rather than resorting to additional modules. A minor detail for some, but a must for watchmaking purists.

  • The iconic Black Bay GMT model is also available in a S&G (Steel & Gold) version, featuring warm colours and a nostalgic touch. Recognisable by its 24-hour graduated rotating bezel with two colours, representing day and night, the Black Bay GMT S&G also gives a subtle aesthetic nod to the history of this watchmaking function.

  • The Black Bay GMT comes with a choice of a riveted steel or steel and gold bracelet, depending on the model, with polished and satin finish. It is also available with a "Terra di Siena" brown leather strap with folding clasp and safety catch, or a black fabric strap with a burgundy or beige band, complimenting the model’s bezel. Made using the Jacquard technique, a traditional method achieved by a hundred-year-old family business from the St-Etienne region of France, the fabric strap is one of TUDOR’s signature features.
