Patek Philippe Ref. 3649/1 Onyx – Bold Geometry, Pure 1970s Elegance

This rare Patek Philippe 3649/1 from 1977 is a striking example of the brand’s sculptural design language of the era. The large rectangular 18k yellow gold case with stepped bezel flows seamlessly into the integrated tubular gold bracelet, creating unmistakable wrist presence.

The flawless black onyx stone dial is pared back to essentials, highlighted by golden dauphine hands and an elegant onyx cabochon crown. Inside beats the hand-wound Patek Philippe Cal. 215, combining refined mechanics with timeless reliability.

Unpolished and in outstanding condition, this is a true statement piece — rare, architectural, and unmistakably Patek Philippe and comes with the original Patek Philippe certificate from 1977.
