Patek Philippe

Reference 4399 is among the more elaborate jewellery wristwatch designs produced by Patek Philippe during the late 1970s, combining hardstone, gem-setting and integrated bracelet construction within a unified architectural composition. The present example is executed in 18k yellow gold and distinguished by its lapis lazuli dial with diamond-set hour markers, framed by a diamond-set bezel and paired with a matching integrated bracelet composed of alternating lapis lazuli and diamond-set links, amounting to a total carat weight of 4.66ct.

The rich ultramarine tone and natural pyrite inclusions of the lapis lazuli create a strong contrast against the yellow gold and brilliant-cut diamond decoration, exemplifying the bold ornamental aesthetic associated with Patek Philippe’s high jewellery production of the period. Conceived as both a timepiece and a jewel, the reference reflects the manufacture’s exploration of decorative hardstone dials and sculptural bracelet architecture during the later decades of the twentieth century.

The watch is powered by the manually wound calibre 16-250, a slim 18-jewel movement adapted for refined jewellery wristwatch production while maintaining the technical standards associated with the manufacture. The seamless continuity between case, bezel and bracelet gives the present example the appearance of a single integrated jewel, characteristic of Patek Philippe’s most decorative bracelet watches of the era.
