The movement of this unique mantel clock was supplied by Jacques-Joseph Castagnet (c.1730-c.1804), the Parisan clockmaker, who worked in his atelier on the rue Saint-Martin. He was elected maître-horloger in 1776. He was among the most well respected clockmakers of his time as his appointment as député of his guild in 1779 and a syndic in 1786 shows. Among the few clocks recorded by Castagnet is the present lot.

Joseph Coteau (1740-1812) was among the most distinguished enamellers in Paris at his time and was well known for his fine clock faces and dials. Among his clients were Robert Robin and Ferdinand Berthoud, both of whom supplied clocks to the Garde Meuble. Originally from Geneva, Coteau worked in Paris after being elected maître in 1778. Between 1780 and 1784 he also worked at the Sèvres porcelain manufactory.
