The Black Bay GMT is an extension of the Black Bay series and features a highly functional complication: the multiple time zone function, also known as the GMT function. Inheriting its dark blue and burgundy color theme from other models in the Black Bay series and recognizable by its rotating bezel, the Black Bay GMT also nods to the early days of this watchmaking function.

Black Bay GMT, Black Bay serisinin bir uzantısıdır ve oldukça işlevsel bir komplikasyona sahiptir: GMT fonksiyonu olarak da bilinen, çoklu zaman dilimi fonksiyonu. Koyu mavi ve bordo renk temasını Black Bay serisinin diğer modellerinden alan ve döner çerçevesiyle tanınan Black Bay GMT, aynı zamanda bu saat işçiliği fonksiyonunun erken dönemlerine göz kırpar.
