Rolex

After 25 years of the manual winding Daytona, the introduction of the automatic reference 16520 marked the most significant evolution in the history of this celebrated model. The watch was completely redesigned and fitted with the new caliber 4030, based on the Zenith El Primero. Although the 16520 was produced for only a dozen years, the model underwent several developments, mainly in the layout of the dial. In fact, five different changes have been identified.

For watch collectors, the patina of the dial plays a key role. More than a sign of authenticity, it reveals the passage of time, reflects the personal life of the timepiece, and gives it a unique character and appeal. With the standardization of watch production and the use of more stable components, most pieces produced after 1990 lack this essential aspect. This rule also applies to the famous Rolex chronograph. However, there are a few exceptions, as demonstrated by this present lot. Some of the 16520s fitted with a black Mark IV dial, produced between 1993 and 1997, have seen their silver chapter rings on their subsidiary dials change color to a tropical brown shade. Referred to as a Patrizzi dial, named after Osvaldo Patrizzi who was the first to discover this distinctive aging, each piece has a different patina, making them unique.
