Notes

Louis Audemars 1782-1833 Born in La Vallée de Joux, at 16 Louis Audemars was apprenticed to Philippe Meylan and soon established his reputation for the fine workmanship of his movements. All eight of Audemar’s sons continued in the family firm, making finished movements, and around 1837 inventing the keyless winding/setting system known today as the Audemars system. In 1848 Audemars began producing complete watches. The company became recognized as one of the best, furnishing the major Swiss and French manufacturers such as Le Roy, Patek Philippe, and Vacheron Constantin, with highly complicated watches and movements.
