Object description

Case and External Features

The GMT-Master II, reference 116758, is constructed with an 18K yellow gold three-body case. The case architecture is characterized by polished and brushed surfaces, complemented by a screw-down crown and case back that provide water resistance. A prominent feature of this model is its elaborate gem-setting; the lugs and crown-guard are adorned with 76 brilliant-cut white diamonds.

The bi-directional revolving bezel serves both functional and aesthetic purposes, indicating the second time zone through a configuration of 22 baguette white diamonds, a single triangular white diamond, and an array of 18 baguette sapphires and 18 baguette rubies. A sapphire crystal with a cyclops lens protects the black dial, which includes luminous round, baton, and triangular yellow gold indexes, alongside the date aperture.
