Reference 16713 brings together stainless steel and 18k yellow gold in the GMT-Master's enduring 40mm round case, 11mm thick and fitted with a screw-down crown. The black dial is populated with luminous dots at the hour markers and luminous hands, ensuring clear legibility, while a scratch-resistant sapphire crystal shields the display. Hour, minute, second, and date functions round out the analog layout.
Powering the watch is an automatic movement, and the GMT complication enables the wearer to track a second time zone simultaneously — a feature rooted in the model's long association with long-haul aviation. The bracelet fastens with a fold clasp and complements the two-tone aesthetic of the case.
This example is accompanied by its original box and original papers dated 2008, making it a well-documented specimen of this recognizable reference within the GMT-Master family.
