First launched in 1955, the GMT was originally manufactured for pilots to keep track of two different time zones. Over fifty years later, the GMT model still retains popularity among aviators and watch collectors. The present watch is an exceedingly rare example from the 1960s, as the watch is fitted with a very special gray bezel. The bezel has faded over time, giving the watch a very attractive appearance. The numerals and graphics on the dial have also aged to a warm orange tone, which match the hands on the dial. Coupled together, these elements present a very compelling and charismatic look.
