UNIVERSAL APPEAL
This model is evocative of an era when the novelty of jet-setting across time zones was matched by glamorous and elegant style. It is fitted with TUDOR’s new mid-size GMT Manufacture Calibre paired with warm hues of burgundy, black and gilt on the bezel. The universally appealing case of the Black Bay 58 has become the model’s calling card, and now it comes in GMT form.

EMBLEMATIC LOOK
In the Black Bay 58 GMT, the case offers the proportions of a 39mm case with a thinner profile than a 41mm Black Bay GMT. The bidirectional rotatable bezel offers very prehensible sides and its insert shows subtly curved numerals aligning with the outline of the outer ring. However, the aesthetic details don’t stop at the case dimensions and bezel. The seconds hand recalls the look of the brand’s early divers’ watches with a lollipop design, while the satin black dial is softly radial-brushed for a very subtle shine under direct light. Ergonomics have evolved as well, with a redesigned crown, reminiscent of the curves found on the crowns of the brand's historical technical watches, that is set flush to the middle case band so that its tube is not visible.

How to set your watch
Select your desired section
A
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.
