Rolex 9 3/4 Description

“Rolex 9 3/4” refers to the size (9.75′′′) of a family of high-grade, manually wound “Hunter” movements, with the Cal. 700 being a prime example. These were reliable time-only movements used extensively in Rolex’s mid-size and ladies’ “Precision” and “Oyster” models from the 1940s to the 1960s. Many featured Rolex’s “Superbalance” for enhanced accuracy and represented a standard of quality for the brand during that era.
