For some ten years, the company continued to expand. It sold clocks, automata, watches and singing birds all over the world, especially in China. But the harsh climate of La Chaux-de-Fonds and the insidious London fog was detrimental to Henri-Louis' precarious state of health.
In 1784, he decided to move to Geneva, finding its artistic and literary life to his taste. Jean-Frédéric Leschot soon joined him and they decided to open the city's first clockmaking manufacture, one year before Vacheron Constantin set up shop, simultaneously introducing the production of timekeepers with major complications. The talent and interest shown by Henri-Louis Jaquet-Droz and Jean-Frédéric Leschot in the civic life of Geneva was quickly noted and approved. The City of Geneva presented both of them with the coveted Bourgeois d'Honneur Award, and welcomed their involvement in municipal activities. Jaquet-Droz was admitted to the newly reinstated Société des Arts, which was very active in the advancement of technical training.
He helped set up a factory-school in Geneva to make cadratures for repeater watches, developed many projects bearing on watchmaking technique and was an advocate for the professions associated with watchmaking. Pierre Jaquet-Droz moved into the house of a clockmaker named Dental, at the corner of rue Molard and rue du Rhône, which housed the workshops and his son's apartment.
