In 1954, Rolex launched one of its most iconic models: the GMT-Master. The timepiece was initially developed in collaboration with Pan American Airlines as to enable their pilots to simultaneously keep track of two time zones when flying from one location to another. Fitted with an extremely fragile Bakelite bezel, reference 6542 was replaced in 1959 by reference 1675 fitted with a more robust metallic insert.

The present watch is an exemplary version of the hallowed reference 1675. Preserved in impressive condition, it most notably displays a beautiful rich black lacquer dial with beautiful luminous markers. There is no telling how any dial will age, yet this particular one has aged beautifully and now displays strong and charismatic "pumpkin" patina - a detail that is highly sought after by collectors today. Furthermore, the dial is glossy, shiny and mirror-like, displaying no signs of cracking which is incredibly rare today. The bezel displays a red and blue tone, and the riveted bracelet is stamped for the fourth quarter of 1965, corresponding with the age of the watch.

Adding even more value to the already impressive condition of the timepiece, the present watch is accompanied by a plentitude of original accessories, adding another layer of collectibility. It is offered with its Rolex guarantee dated March 7, 1966, Bureaux Suisses de Controle Officiel de la Marche des Chronomètres, original invoice dated March 7, 1966 stating the watch was sold at Ollibant & Botsford Ltd for 83 pounds, tag, presentation box and outer packaging.

Such attractive and complete examples barely come on the market, underlying the collectibility of the present watch.
