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 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.
