Notes

Robert & Courvoisier
The company was founded in 1770 by J. Robert of La Chaux-de- Fonds, who in 1781 went into partnership with his son-in-law Louis Courvoisier. The company was first called J.Robert Son & Co., in 1805 Robert, Courvoisier, & Co., and in 1816, Courvoisier & Co. Along with the Jaquet-Droz firm, they were the most important makers of musical clocks.

During the last quarter of the XVIIIth century, several watchmakers tried to produce watches with dead center seconds hands, much in favor among the scientists and in the Chinese market. The attempt made by Moïse Pouzait with a lever escapement associated with a large second beating balance, thanks to its spectacular aspect, was much appreciated on the Chinese market in spite of its inertia sensitivity, before the invention by Jacot of the so-called “Chinese duplex” escapement enabling the production of dead center second watches.
