3135

This watch features the calibre 3135, a self-winding mechanical movement entirely engineered and manufactured by Rolex. Like every Rolex Perpetual movement, the 3135 is a certified Swiss chronometer, a status for high-precision timepieces that have satisfied the Swiss Official Chronometer Testing Institute (COSC) requirements. It includes a Parachrom hairspring for improved resistance to shocks and temperature changes, and its Oyster-style architecture provides outstanding reliability. (Chronometer)
