Rolex 750 Description
The Rolex Caliber 750 is a high-quality, manually wound movement from the late 1940s and early 1950s. It is most notably found in rare Rolex Oyster models with “Rigid Hooded” lugs, like the reference 4647. This time-only caliber was often a certified chronometer, featuring Rolex’s Superbalance for enhanced precision. It represents a specific and uncommon branch of Rolex’s robust mid-century, manual-wind movement production.
