Black Bay 58 GMT

HKD $34,100
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. Recognizable by its rotatable bezel, which derives its deep blue and burgundy color 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.
