Rare and highly coveted, the present Rolex Daytona wristwatch is set apart from its contemporaries due to its remarkable overall condition as well as its dial. The timepiece features a very attractive 'Four Lines' dial with inverted 6 to the hour subsidiary dial of the chronograph. Furthermore, the watch is distinguished by its early bezel, calibrated for 200 instead of 400 units per hour.

Legendary chronograph, the reference 16520 was the first chronograph of the Rolex manufacture encompassing an automatic movement derived from a Zenith ebauche. Built with a larger case than its predecessors and a sapphire-crystal glass, the timepiece encountered great success and throughout the years has become highly sought after by collectors.
