Constant Girard

Constant Girard began his career apprenticed to the watchmaker of La Sagne, in the mountains of Neuchâtel, Switzerland.

Constant Girard-Perregaux was equally active in the social, political, and economic life of La Chaux-de-Fonds.

Constant Girard devoted many long years to studying and designing diverse systems of escapements and in particular that of the tourbillon.

Invented at the very beginning of the 19th century, the tourbillon counteracted the differing effects of gravity on a watch held in the vertical versus horizontal position, thanks to a mobile cage that carries the settling organ.

[2] Constant Girard redesigned the three bridges, part of the watch movement, into the form of arrows parallel to one another.
