Rolex 1565 Description

The Rolex Caliber 1565 is a highly regarded automatic chronometer movement and the direct predecessor to the Caliber 1575. It powered iconic models like the early Datejust and GMT-Master. Operating at a lower frequency of 18,000 vph, it was known for its robust construction and reliability. This movement features a date complication and was a cornerstone of the 1500-series family before Rolex transitioned to higher beat rates for improved accuracy.
