Launched in 1988, the ref. 16500 series comprised the first automatic chronographs to be introduced by Rolex, marking an end to the production of hand-wound Daytona models. The series initially used a modified Zenith El Primero movement, which was later replaced by the 4030 caliber developed in-house by Rolex. This new movement was itself based on Zenith's caliber 400 and contained about 200 modifications.
The present reference 16520 is from the R-series, featuring a so-called "porcelain" dial, produced in an exceedingly small number only. The dials were in fact layered with a coating resembling porcelain, signatures and scales printed on top, giving it an almost floating appearance. The intention behind this version was to render it a more appealing look. Due to high production cost, manufacture of these dials was soon ceased, rendering the ref. 16520 "R" models much sought after collectors watches.
