1983 - 2007
By the time Rolex introduced the GMT-Master II in 1983, the red and blue bezel insert from the original GMT-Master had already earned its now-legendary "Pepsi" nickname. While the half red, half black bezel insert from the "Coke GMT" is somewhat reminiscent of a full bottle of Coca-Cola with its red and white label, the "Coke" nickname most likely came about as a response to the previously well-established "Pepsi" nickname of the original version of the GMT-Master, with its red and blue bezel insert.
