Patek Philippe was founded in Geneva in 1839 by Antoine Norbert de Patek and François Czapek; the watchmaker Adrien Philippe joined Patek in 1845, and the firm took its current name in 1851. Still independent and family-owned, the manufacture is known for hand-finished movements and for complications such as perpetual calendars, minute repeaters and astronomical displays.
Key collections include the Calatrava, the classic round dress watch; the Nautilus, the steel sports watch designed by Gérald Genta in 1976; the Aquanaut; and the Grand Complications, which include models such as the Sky Moon Celestial. Ladies' watches, the Golden Ellipse and the Gondolo are also part of the catalogue.
