TUDOR is expanding its Black Bay line by presenting a model with a highly functional complication: a multiple time-zone function
– 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 derives its deep blue and burgundy colour theme from other models in the Black Bay line, but in a matt version, the Black Bay GMT is also a nod to the early days of this watchmaking function.
Additional time zones are indicated by a red snowflake hand, TUDOR’s aesthetic hallmark, which spins around the dial in 24 hours, as well as a bidirectional rotatable bezel that is also calibrated for 24 hours. The twelve daylight hours are printed on the burgundy section and the night-time hours on the blue. With a steel case, 41 mm in diameter, the Black Bay GMT model is waterproof to 200 metres (660 ft) and designed to withstand the elements. Its winding crown tube is in satin-brushed steel, new for the Black Bay line and aesthetically in keeping with the case and winding crown. Its contrasting black dial means that it is legible in all conditions, including night-time, thanks to its luminescent hour markers. The dial features a GMT marker at 6 o’clock.
