In the early 1950s, Rolex teamed up with Pan American Airlines to design a watch for their team of pilots. This led to the design of the Rolex GMT-Master with a red and blue bezel that matched the airline’s color scheme. Not only did this watch display a second-time zone, its unique, dual-colored bezel also allowed Pan Am’s pilots to quickly differentiate between daytime and nighttime hours. Nowadays, you’ll hear this watch model referred to as the “Pepsi” because of its resemblance to the soda brand’s classic red, white, and blue logo.
