Notes

Duplex-Jacot Escapement

During the last quarter of the 18th century, several watchmakers tried to produce watches with dead centre-seconds hands, much in favour among the scientific community. The first attempt, made in Geneva by Jean-Moïse Pouzait (1743-1793), circa 1786, featured a lever escapement associated with a large seconds-beating balance (the model of this escapement was presented to the local Société des Arts).

Due to its spectacular aspect, and in spite of its inertia sensitivity Pouzait’s escapement was much appreciated by the Chinese before the invention by Charles-Edouard Jacot (1817-1897), a watchmaker from La Chaux-de-Fonds (Neuchâtel mountains), circa 1840-1850, of the so-called duplex-Jacot or “Chinese duplex” escapement, with double-tooth arrangement. The Jacot escapement, like any duplex escapement, is a frictional one the friction from the escape wheel is constantly present. Enabled inexpensive production of dead centre-second watches it was often used in the watches made for the Chinese market.
