Notes

This Rolex reference with this type of color-change dial tends to be unique due to the permanent and progressive discoloration of the dial by ultra-violet light. Daytona watches with this type of colorchange dial are called ?The Patrizzi? by collectors, as Osvaldo Patrizzi was the first person to see and describe this type of change to the chapter rings of the subsidiary dials. A similar watch is illustrated in ?Rolex, Collecting Modern and Vintage Wristwatches?, by Osvaldo Patrizzi, Guido Mondani Editore, Genova, 2006 Edition, vol. 1, p. 154.
