Rolex 1161 Description

The Rolex Caliber 1161 is a compact automatic movement designed for ladies’ watches. As the date-equipped version of the Caliber 1160, this COSC-certified chronometer was a technical achievement in miniaturization. Operating at 19,800 vph, it powered various ladies’ Oyster Perpetual Date models, offering them the same precision and reliability as their larger counterparts.
