The Last Family-Owned Independent Genevan Watch Manufacturer Since 1839 without interruption, Patek Philippe has been perpetuating the tradition of Genevan watchmaking. As the last family-owned independent watch manufacturer in Geneva, it enjoys total creative freedom to entirely design, produce and assemble what experts agree to be the finest timepieces in the world – following the vision of its founders Antoine Norbert de Patek (1839) and Adrien Philippe (1845). Thanks to its exceptional know-how, Patek Philippe maintains a tradition of innovation hailed by an impressive repertoire of more than 80 patents.
