Patek Philippe 10-Day Power Reserve 5100J

18K gold Patek Philippe 10-Day Power Reserve ref. 5100J. An exceptional 18K yellow gold Patek ref. 5100J, specially produced in the year 2000 to commemorate Patek Philippe’s entry into the third millennium. This reference was issued in a strictly limited edition of 1,500 pieces. The watch features an unusual rectangular case, inspired by the historic “Manta Ray” case design of ref. 2554, giving it a distinctive and architectural presence on the wrist. This example is brand new, still sealed in its original factory plastic protective bag. Power comes from the impressive manual-winding 10-day power reserve cal. 28-20/220, a movement developed specifically for this commemorative model. The watch is fitted with a brand-new, sealed alligator leather strap and an 18K yellow gold buckle. It is accompanied by an exceptionally complete set, including the Patek Philippe certificate of origin, limited edition attestation, COSC chronometer certificate, instruction manual, commemorative medal, leather folio, fitted presentation box, and outer packaging.
A museum-grade example of one of Patek Philippe’s most ambitious modern commemorative creations—rare, untouched, and historically significant.
