Details

The TUDOR Black Bay GMT is made of the right stuff. First off, it sports an incredibly useful multiple time zone complication also known as a GMT function that establishes local time without losing sight of the time in two other time zones. Recognisable by its rotatable bezel, which borrows its deep blue and burgundy colour scheme from other models in the Black Bay line, but in a matte version, the Black Bay GMT is also a nod to the early days of this high flying aesthetic. Now TUDOR has added the option of an all new opaline dial that perfectly complements the iconic colour scheme of the Black Bay GMT. Opaline isn’t quite white, instead there’s a slight silvery hint to the dial. Through a galvanic process, a matte white grey finish is applied to the dial, and the marker surrounds are darkened to create a noticeable contrast.
