Rolex 1160

The Rolex Caliber 1160 is a high-precision automatic movement that served as the time-only engine for many ladies’ Oyster Perpetual models. As the base for the Caliber 1161, it shared its compact, COSC-certified design. Operating at 19,800 vph, its slim profile and reliability made it a premier choice for Rolex’s non-date ladies’ watches of the era, proving that small size did not mean a compromise in performance.
