Polish watchmaker Antoni Patek started making pocket watches in 1839 in Geneva, along with his fellow Czech-born Polish partner Franciszek Czapek. They separated in 1844, and in 1845 Patek joined with the French watchmaker Adrien Philippe, inventor of the keyless winding mechanism. Patek Philippe & Co was founded in 1851. Patek Philippe popularized the perpetual-calendar, split-seconds hand, chronograph, and minute repeater in watches. In 1935, the manufacturer was brought to American markets by New York-based Henri Stern Watch Agency, where it was sold as a sister brand alongside Universal Geneve. The company has been owned by the Stern family since 1932, and, as of the late 2000s, led by Philippe Stern and his son Thierry Stern, who took over the reins from his father in 2010. Patek Philippe slogan remains inspiring: "You never actually own a Patek Philippe. You merely look after it for the next generation."
