The Rolex GMT-Master II has its roots in the original GMT-Master model that was introduced back in 1954 as a request from Pam American Airlines, which was looking for a watch that could display the exact time in two time zones simultaneously. GMT (Greenwich Mean Time) was used as the international civil time standard at the time. The watch became an instant success among airline pilots and was soon adopted by other airlines worldwide. The GMT-Master II model was released in the early 80s alongside the original model. The main differences are that it features a movement capable of adjusting the hour quickly without disturbing the minutes, seconds or GMT hand. Furthermore, since it features a rotating bezel, the watch is able to display a 3rd timezone. Newer models feature larger cases, hands, and hour markers. The ceramic bezels are also designed to be stronger and scratch resistant. This is a very elegant Rolex watch that is both functional and classy, excellent for the world traveler.
The GMT-Master became a symbol of precision, functionality, and style after its release. Rolex has since continuously worked to improve the GMT-Master, making it a timekeeping marvel that attracts global adventurers and watch aficionados. The GMT-Master's sleek, classic style is instantly identifiable. The watch has a 40mm Oyster casing in stainless steel, 18-karat gold, or Rolesor. Rolex's accurate, reliable calibers power the GMT-Master. The watch's many movements have shown Rolex's accuracy in timekeeping. Modern travelers want accuracy and efficiency, which these developments provide. Rolex's GMT-Master dial exemplifies readability and precision. The traditional design has attached 18-karat gold hour markers and luminous technology for low-light visibility. The bezel is usually blue and red to distinguish day and night in the second time zone. This innovative design was initially meant for pilots and travelers to track their home time zone when on long-haul flights or abroad.
