Charles A. Girardier was born in 1759 in Geneva and died in 1839. He was a well-known and appreciated master watchmaker throughout Switzerland. He signed all his watches with  Girardier the elder, Girardier l’Ainé in French as if he wanted to give himself even more importance and respectability. The ‘connoisseurs of Haute Horlogerie’ considered Girardier an outstanding craftsman. In 1810 the very respectable ‘Society of the Arts of Geneva’ awarded him for his whole watchmaking work.
