                            The GMT Master was first commissioned in the 1950s by pioneering airline Pan Am, and was designed for aviation. An increase in flight distances created demand for a watch that was able to tell the time in two different parts of the world simultaneously, so Rolex built it with an additional hand that could be set to a second time zone. By the 1980s, the watch had developed into the GMT Master II and was already a favourite among collectors. This model represents a significant upgrade for the watch, boasting an aerospace-grade “superalloy” steel case and cerachrom inserts in the bezel. The LN moniker stands for Lunette Noir—signifying that it uses an all-black bezel.
