Rolex 1135 Description

The Rolex Caliber 1135 is an early automatic chronometer movement designed for ladies’ watches, serving as the date-equipped version of the Caliber 1130. It powered ladies’ Oyster Perpetual Date and Datejust models, offering a then-modern beat rate of 19,800 vph for high precision. This movement was key in establishing the reputation of Rolex’s ladies’ collections as being both elegant and technically proficient.
