First introduced in 1955, the GMT Master II collection by Rolex was designed to meet the requirements of international pilots. These watches were officially used by several intercontinental airlines including the iconic Pan American Airways. In the 1960s, when Concorde had performed its final test flight, both Brian Trubshaw (British test pilot) and André Turcat (French test pilot) were wearing GMT Masters.
Since 2005, the monobloc bezel and the Cerachrom bezel are being used to make these watches. They are manufactured from an extremely hard ceramic material that renders it virtually scratchproof and gives it anti-corrosion properties. Thus the colour of your timepiece will not fade or lose sheen over time. The graduations and numerals are inscribed using a thin layer of platinum or yellow gold. To produce a Cerachrom bezel, it takes approximately 40 hours. Your wrists expand sometimes due to an increase in temperature, thus making wearing a watch uncomfortable. The patented Easylink used in these watches lets you increase the length of the bracelet by 5 mm to keep you comfortable. All the watches in this series feature an oyster bracelet and have flat three-piece metal links attached at the end for your ease of use.
GMT Master II timepieces feature a separate 24-hour hand and a 24-hour rotatable graduated bezel, which enables you to conveniently read the time of three different zones in the world and lets you see time from two zones simultaneously. The fourth arrow tipped hand circles the bezel once in every 24 hours. A water-resistance of 300 metres enhances flexibility and durability and renders the watch with a spirit of adventure both on land and sea. The mechanical self-winding 3186 movement keeps your timepiece precise to every second.
