Rolex 3175 Description

A self-winding mechanical movement that pioneered the independent hour hand functionality in Rolex’s GMT line. Exclusively used in the first GMT-Master II (Ref. 16760 “Fat Lady”), it is a COSC-certified chronometer built on the robust 31xx platform. Its short production run makes it a relatively rare and historically significant caliber, representing a major step forward in traveler watch functionality.
