Rolex 2135 Description
The long-serving engine of the Lady-Datejust for over 15 years, this automatic caliber defined the modern ladies’ Rolex. Introduced in 1983, it brought a high-beat frequency (28,800 bph) and a quickset date to the line for the first time. As a COSC-certified chronometer, it was a robust, reliable, and accurate movement that powered a generation of Rolex’s most popular watches.
