Jacques-Joseph Castagnet

C
Castagnet à Paris
Jacques-Joseph Castagnet was one of the finest Parisian horologists of the last quarter of the 18th century. In 1776, after being received maître, he opened a workshop in the rue Saint-Martin, soon gaining fame and an excellent reputation. Successively becoming deputy of his guild sometime between 1779 and 1783, then trustee (syndic) in 1786, he worked with the finest artisans of his period, including the renowned enameller Joseph Coteau (1740-1812) whose signature also appears on the present clock.
Coteau was born in Geneva, where he became peintre-émailleur (enamel painter) of the Académie de Saint Luc in 1766, settling in Paris several years later. A special technique for painting enamel in relief, invented by him and Parpette for the decoration of Manufacture royale de Sèvres porcelains, bears his name.
