Rolex GMT-Master II -16710 - Very Good (With papers) - Watch only

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 16710 has many similarities with the 16700. The case has the same 40mm diameter, but the 16700 has a 3175 Caliber and the 16710 has a 3185 Caliber. This model is available with blue and red inserts called "Pepsi" or with full black inserts. This model's novelty is the black and red bezel also called "Coke".
