The present watch is one of the first examples of GMT-Master, reference 6542 and the most sought after Rolex GMT Master model.
First produced in 1954, reference 6542 was developed for Pan-Am Airlines after the company requested a reliable watch that could display more than one time zone at once (for use on transatlantic flights). Since then, the GMT has gone through countless variations.
It's instantly recognizable by the long and slim hand for the second timezone, and the lack of crown guards on the case.
