Rolex GMT Master II

[1] The Rolex GMT-Master wristwatch was originally designed in collaboration with the Pan American Airways and issued by the airline to their crews on long-haul flights.

[citation needed] In the early 1980s the Rolex GMT-Master II was released (although production of the original version continued alongside it until 1999).

This new model features a number of technical changes, such as Rolex's patented Parachrom hairspring as well as a larger Triplock crown (from the diver's watches).

The new model also has several cosmetic changes, such as larger case, hands and hour markers and also a new bezel made using an extremely hard ceramic material that is designed to be more scratch and fade resistant.

[4] In 2013, Rolex created the first two-tone ceramic bezel, in blue and black, for the steel GMT-Master II nicknamed “Batman”.

[9] In 2021, Rolex re-issued the Oyster bracelet as an option for both the red-and-blue "Pepsi" and the blue-and-black "Batman" in addition to the existing Jubilee that was released in 2018 and 2019, respectively.
