In archives one also finds François-Pierre-Gaston Jolly. Gaston became a master watchmaker on 6 May 1784. He was located in the Rue des Arcis (1784), later in the Rue Michel le Compte, which was renamed Rue Michel le Pelletier. From time to time, one also finds the signature as Gaston Joly. Jolly used watch cases from Robert and Jean-Baptist Osmond. When his son joined or took over the business, the watches were no longer signed Gaston Jolly, but Gaston Jolly Fils à Paris.
