Founded in 1875 by Jules-Louis Audemars and Edward-Auguste Piguet, the manufacturing headquarters of Audemars Piguet are nestled in the Joux Valley in Switzerland. At the turn of the twentieth century, the factory employed more than seventy craftsmen who developed traditional pièces as well as revolutionary watches. This book on the history of the company includes information on the slimline jeweled watches for women in the Art Deco era, chronographs in the Forties, the first perpetual calendar watch in 1957, the famous Royal Oak-the first high-end sports watch-in 1972, and the ultramodern Millenary MC12 in 2008, the mechanisms, the meticulous processes by which they are developed, and their technical and stylistic inventions.
