An 18ct yellow gold Neptune watch, Patek Philippe. Reference 5085J. Complicated automatic movement with date moonphase and power reserve functions and 22ct gold micro rotor, silvered dial with appliqued Arabic numerals. Bracelet is solid gold with screw down crown-lumed hands and dial. Box and a copy of the extract from the Patek Philippe achives. Dial signed. This model was produced in very low numbers in yellow gold (only around 100 examples) and shows a large scope for appreciation and investment. Purchased new on September 30th 1999 in the second year of its release. Some of the characteristics of this watch that lend to its rarity and collectability.
