subject: The History of the GMT [print this page] The early GMT Masters are now highly sought after collector's items and the watch remains one of the most popular timepieces that Rolex makes. The GMT Master can be purchased with several bezel and cases options. The colorful bezels allow a sporty look and the steel and yellow gold cases, or two toned cases making use of steel and gold, give the watch the classic Rolex touch. The GMT Master is a favorite of pilots, seamen and the military for its combination of usefulness, durability and style. The successor to the GMT, the GMT Master II is now one of the most popular luxury watches in the world.
