The Zenith caliber 4030 was the last outsourced movement supplied to Rolex for their chronograph range and Rolex's subsequent transition into in-house movements makes the Zenith Daytona extremely sought after by Rolex collectors. Throughout its production from 1988 to 2000, the Reference 16520 underwent five distinct evolutions as Rolex continuously refined its design. The present example features the desirable Mark 1 dial, distinguished by two traits that make this early automatic Daytona particularly collectible. Most notably, the word Cosmograph is positioned noticeably lower than the four lines of text above, creating the so-called “Floating Cosmograph” configuration, seen only in the first couple years of production. In addition, it features the sought-after “inverted 6” on the 6 o’clock subdial. While subtle, these details hold significant weight in the world of vintage Rolex collecting, enhancing both the rarity and desirability of this already iconic reference. We are pleased to offer the present Reference 16520 complete with its full suite of accessories in wonderful condition.
