Reference 16520 is among Rolex's most innovative models ever produced. Housing the iconic Zenith-based caliber 4030 mechanism, the model was fitted with the first automatic chronograph movement in the firm's history. At the time of launch in 1988, it quickly became a cult classic and garnered an immediate waiting list at Rolex retailers. Today, the Zenith Daytona has become an even more collectible watch due to its rarity, good looks and importance within the history of Rolex.

The present example is remarkable due to a number of factors: its provenance, its accessories and its condition.

Offered by the original owner, this watch was in fact sold in Geneva and not by a simple retailer, but by the maker itself: the guarantee proudly states under the retailer name field: “Montres Rolex S.A."

Furthermore, in an example of perfect Swiss efficiency, the original owner jealously safeguarded not only all the original accessories, but even the original invoice and the original bank wire receipt (from which one can see the watch was paid 4’760 CHF).

Finally, the piece is preserved in excellent condition: obviously sparsely worn, it features an unpolished case with strong edges and satin finish, and only the slightest hint of wear. Combining provenance, condition and undoubtedly one of the most complete set of accessories one can ever wish to find accompanying a 16520, the present watch is a rare occasion for the most spoiled of collectors.
