TUDOR's famous Black Bay divers' watch is available with a GMT function that establishes local time without losing sight of the time in two other time zones. Fitted with the Manufacture Calibre MT5652, the Black Bay GMT sports a 24-hour graduated rotating bezel with two colours.

The Black Bay GMT is an extension of the Black Bay line with a highly functional complication: a multiple time-zone function also known as a GMT function. Recognisable by its rotatable bezel, which derives its deep blue and burgundy colour theme 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 watchmaking function.
