As a signature piece from Patek Philippe's lineage of horological innovation, this Annual Calendar beautifully balances intricate complication with daily versatility. Originally patented by the Manufacture in 1996, the annual calendar mechanism requires adjustment only once a year at the transition from February to March. Cast in radiant 18K yellow gold and paired with an elegant cream dial, this timepiece stands as a masterful expression of traditional luxury and mechanically complex craftsmanship.
