Model Profile: Rolex GMT-Master

Posted by on

 The GMT-Master is one of the pillars in the famous Rolex sport watch collection, alongside the Submariner and the Daytona. Easily identifiable with it’s two-colored bezel, the GMT-Master has become an icon among vintage watch collectors, with some owning a number of examples of this same model. 


In the 1950’s, the GMT-Master was developed in cooperation with the Pan-American Airlines to assist pilots with telling time in multiple time zones. As flight technology increased, so did flight times and distances, meaning pilots would be crossing through a number of time zones in one flight. To keep pilots on correct time, Rolex created the GMT-Master with a hand that could be set to Greenwich Mean Time (GMT), the standard time used by pilots, while the other hour hand could be set to local time.

The iconic red and blue bezel, often referred to as a “Pepsi bezel,” was made to tell day hours from night hours, red being daytime and blue being evening. As the GMT-Master evolved, it also became available with a red and black bezel, often called a “Coke” bezel, and gold and brown bezel known as a “Root Beer” GMT.

History of the Brand

 

Rolex is arguably the most recognized and popular watch brands in the world. The company was established as Wilsdorf & Davis in London, England in 1905 by Hans Wilsdorf and his brother-in-law, Alfred Davis. Their initial business was importing Swiss movements and placing them in high quality cases to be sold in jewelry stores around England. As a result of wartime taxes levied on luxury imports in 1919, the company was moved to Geneva, Switzerland and became the Rolex Watch Company. 

After his wife’s death in 1944, Hans Wildorf established the Has Wildorf Foundation to which he left all of his shares in the company, ensuring much of the companies income would go to charity. The brand continued it’s tradition of excellence, release innovative watch designs and setting a high standard for the horological world. 

 

How it Works

The GMT is an automatic or self-winding watch, which means the mainspring is wound by the motion of the wearer’s arm. As the wearer moves about the day, the energy from their movement swings a weight or rotor, which turns on a pivot. The circular movement of the pivot winds the watch just as a manual or wind watch. The GMT hand, which can be identified by the slimmer hand with a triangle at the end, is set to Greenwich Mean Time (GMT).
