Rolex created the first Oyster Perpetual GMT watch in the 1950s for Pan Am pilots who wanted a quick way to check and know the time in different timezones. The classic design has gone through various refinements, but it remains pretty much the same today.
The original Rolex GMT was one of the first watches on the market that could tell time in two timezones at once. Essentially, Rolex added a fourth hand (the green hand with the large arrow head, or the GMT hand) that circles the dial in 24 hours. The great innovation at the time was to create a rotating bezel with 24 hour markers that can be adjusted as one moves to different timezones.
Note, comes with original box, outer box, tag, manual. It does not include original warranty card.
