Pre-Owned Rolex GMT-Master II Ref 116713 The first GMT Master II was introduced in the 1980's, bringing with it a new movement with an independent 24-hour hand. Its predecessor, the GMT Master, featured a similar design but did not offer the independent hand. This upgrade allowed the wearer to read two time zones via the dial in addition to a third via the 24-hour bezel. The 1167xx series is the newest generation of GMT's, boasting a new case and bracelet design with a broader width on the wrist and a heavier weight via solid components,
