Rolex 3075 Description

The final evolution of the original GMT-Master caliber, powering the Ref. 16750. This COSC-certified movement introduced crucial upgrades like a high-beat frequency (28,800 bph), hacking seconds, and a quickset date. While the 24-hour hand was not independently adjustable, the movement represented a significant leap in convenience and precision for the GMT-Master line before the advent of the GMT-Master II.
