I don’t really ever understand the Rolex Oyster Perpetual Cosmograph Daytona until you own the Zenith version, specially the so called Patrizzi dial.
Patrizzi dials are found on a very short timeframe, 1994-1995.
During this timeframe, Singer (alas Rolex chronograph dial maker), used an organic lacquer on the dials that caused them to get a very attractive dark patina, especially (but not limited to) on the subdials.
This particularity was evident during Osvaldo Patrizzi’s iconic Antiquorum auction in 2006, when this coloration defect was widely observed.
Every (original) black dial Daytona on this range is a correct Patrizzi Daytona, regardless of how intense is the patina. The patina is not a constant. Beware however of cooked dials! They even come in totally incorrect years and even in the very late 1988 luminova ones! So if you think that a very dark black Zenith dial is the indicator of a Patrizzi, you better improve your due diligence! 🔎🧐
My preference for the “Zenith” Daytona goes beyond this particularity. I love its sleek hands and markers.. the fact that it coms (mostly) with tritium lumen and beyond everything, the fact that the chrono subdials are aligned at 3-9, instead of the in-house Cosmograph, which has subdials a bit higher.
