Between 1988 and 2000, Rolex produced the first automatic version of the Daytona, the reference 16520. The 40mm sports chronograph relied on a Zenith El Primero caliber, extensively modified by Rolex and named the cal. 4030. Over the course of its 12-year life, the reference 16520 was produced in 5 different series and available in stainless steel, yellow gold, white gold as well as a bi-colour version.
The present 16528 'R series' is from late 1988. This lot combines two most attractive and collectible features. Firstly, it is fitted with its original first series bezel calibrated to 200 units. Furthermore, it bears an early and correct second series 4 lines dial with inverted 6 to the hour register.
In addition, this early reference 16528 is mounted on a yellow gold Oyster bracelet bearing the early clasp with no safety lock. The case displays some oxidation marks around the upper chronograph pusher, combining dark blue hues with the warm tone of the yellow gold. This rare early Zenith Daytona is a great piece for any Rolex collection.
