GMT Master II 16710 History

The Making of a Masterpiece - GMT Master II 16710

When the Pan-Am company needed a watch that could display multiple time zones simultaneously Rolex was able to deliver. Having a watch that kept good time was a necessity for pilots in those days.

Pan-Am pilots were not the only men in the air wearing these watches, however. NASA, US Air Force pilots and traveling business people all adopted the watch.

The first GMT-Master to hit production was the reference 6542. Introduced to the public in 1954 and was in production until 1959. The original models featured a bakelite bezel that cracked easily. Two years later this bezel would be replaced with a stronger aluminum bezel.

The Rolex GMT-Master II you can purchase today has come a long way since the original model 6542, which is evident in the GMT Master II model 16710.
