3165

Calibre 3165 is a self-winding mechanical movement fully engineered and built by Rolex. It incorporates a Parachrom hairspring and Paraflex shock absorbers to provide superior shock resistance and stability in demanding conditions. As a certified Swiss chronometer, it has passed the precision evaluations of the Swiss Official Chronometer Testing Institute (COSC), and its Oyster movement design guarantees high reliability. Uniquely for Rolex, this calibre presents the date via a subdial located at the 3 o'clock position.
