Rolex Rolex GMT Master II 16760

The Rolex GMT Master was developed by Pan Am Airlines for airline pilots in the 1950's. This model was the first to introduce the "dual time zone" feature, which was designed to reduce the impact of jet lag. The original 1955 model (reference 6542) had a graduated disc with two colors: red for daytime and blue for nighttime. The second time zone is read with a triangular hand that makes a full 24-hour revolution. This model was mostly made of steel, although there are also yellow gold variants that have different details. The Rolex GMT Master II 16760 was the first GMT Master II produced by the brand. This reference has a thicker case, a wider bezel and larger crown guards compared to previous models. These features led the 16760 to be nicknamed "Fat Lady" or "Sophia Loren" as a result of comparing the watch's new curves and Italian beauty.
