In post #6 of
this old 2014 thread, David/crowncollection seems to refer to the linen or crosshatch finish as Florentine and the pockmarked one as Morelli (with photos of Stella examples of each!), but even he seems to interchange the two terms in his later posts.
To further muddy the waters, there’s this (from a 2011 Kingair post) -
Rolex Day-Date 1802 Smooth
Rolex Day-Date 1803 Fluted (Most Commonly seen)
Rolex Day-Date 1804 Diamond
Rolex Day-Date 1805 Diamond (sapphires)
Rolex Day-Date 1806 Morellis A.K.A "Florentine"
Rolex Day-Date 1807 Bark Finished
Rolex Day-Date 1810 Waved
Rolex Day-Date 1811 Moiré/Morellis Variant
Rolex Day-Date 1816 Diamond baguette
Rolex Day-Date 1817 Emerald / Ruby / Sapphire / Diamond
This does seem like an answer which the combined knowledge of TRF should have readily at hand, but there are very few research, scholarship and reference sources for DDs, compared to the sport models. (E.g., I think I’ve only ever seen one pic of the 1810/“waved” DD bezel; I’ve never seen one in person.) I don’t have the Pucci Papaleo DD book, maybe it has an answer?
