This 1971 Rolex GMT-Master 1675, also known as the "Pepsi", is one of Rolex's most iconic watches ever produced. The 1675 was produced from 1959 to 1980, and contains many different variations. This particular example is known as the "Mk1. Long E", meaning that it has the matte black dial with the extended 'E' on the Rolex logo. The watch contains the 1575 movement, an upgraded version of the 1565 found earlier.
