Frères Esquivillon & Dechoudens
Geneva watchmaker Jacques Dechoudens (1728-1801) and brothers Joseph Esquivillon (1714-1798), Jean François Esquivillon (1733-1813) and Gédéon-François Esquivillon (1717-1799) founded a workshop in Paris which produced high quality verge pocket watches. Esquivillon & De Choudens was a French clockmaking and watchmaking firm based in Paris during the late 18^th and early 19^th centuries. They were known for producing high-quality pocket watches, often with elaborate cases and decorations. The firm produced a variety of pocket watches, including ones with gold and enamel cases, as well as diamond decorations. Their watches were highly sought after by wealthy collectors and nobility at the time. Esquivillon & De Choudens was in operation for over 60 years, from around 1765 to 1830, indicating their success and reputation in the French watchmaking industry during that period.
