CALIBRE 3136

Introduction and Launch: The Rolex calibre 3136, is an automatic movement designed for the Datejust II, introduced in 2010. Measuring 2.5 millimeters larger than the calibre 3135, it was specifically developed for the 41mm Datejust rather than simply adapting an existing movement to a larger case. Rolex engineered this movement with precise dimensions to meet the demands of modern daily wear for watches exceeding 40mm. The calibre 3136 is a time-only, three-hand automatic movement without a date function, reflecting Rolex’s commitment to innovation and precision in larger timepieces.
