Lot Essay
It is highly unusual to find the Cosmograph Daytona model with colour-change dial in New Old Stock condition with no signs of use, still retaining the protective factory bezel covering and green Rolex hologram reference sticker on the back of the case, the present watch is one of those rare gems
Some manually wound Daytonas present dials that with time change colour: the black paint reacts with light and other environmental factors and turns a variety of colours, from dark chocolate to nearly orange. These dials are the so-called tropical dials, and are in very high demand among collectors. This process can occur also on Zenith Daytonas, however it usually affects the white chapter rings, which turn brown, and can occur only on watches manufactured between 1993 and 1997, while with manually wound Daytonas it can occur on any watch. Consequently, one can infer that Zenith Daytonas with tropical dials are even rarer than manually wound ones.
