On May 1, 1839 the legendary watch company was founded in Geneva under the name of “Patek, Czapek & Co.”. In 1844, during an exhibition in Paris, Patek hears about a person named Jean Adrien Philippe who made an astonishingly thin pocket watch which could be wound and set without a key. Philippe became the technical director of the company the following year. In 1845, the company becomes “Patek & Co.” and in 1851 it got his final name “Patek Philippe & Co.” to reward the genius Jean Adrien. For the last 150 years, Patek is the pioneer for wristwatches. In 1927 comes the first perpetual calendar then the world time in 1937 and tourbillon in 1945. Since 1997, Patek produce 30,000 watches per year. In 2005, the company brought out an escape wheel made of monocrystalline silicon under the banner of “Advanced research” and then in 2006 by a silicon balance spring with the name “Spiromax”.
