Rolex Daytona 16520

Rolex DAYTONA 16520 / W51xxxx PATRIZZI STEEL

1994 Used, minor to no usage signs Box: No Documents: No Brand : Rolex Model : Daytona Zenith Reference : 16520 Case material : Stainless Steel Case diameter : 40 Glass : Sapphire ROLEX DAYTONA REF. 16520 / W51xxxx PATRIZZI DIAL YEAR 1994 More strangely, the huge gulf in value is all down to a rare and quickly corrected mistake. The black ref. 16520’s made between 1994 and 1995 used an organic varnish, called Zapon, to protect the Daytona’s face. Unrecognized at the time, the lacquer did not provide sufficient coverage and, over the years, the silver outer tracks on the iconic sub dials have oxidized, turning a definite brown color as they react with UV rays. Even more importantly to collectors, the changes do not stabilize and continue to take effect the older the watch gets. It means every one of the so-called Patrizzi dials is unique, and in the world of classic Rolex, unique often equals expensive.
