The Fernand Berthoud Chronomètre FB RES comes in 200 possible variations if you push the configurator of this timepiece to the limits
Remontoire comes from “remontoir d’egalité”, French for a device that provides constant power to the escapement of a movement. With regular movements, energy from the mainspring slowly decreases as a watch runs down. This has a negative effect on the accuracy.
.
A remontoire usually has an extra (spiral) spring attached to one of the train wheels, which is periodically wound up by the mainspring. As long as there is enough energy from the mainspring to wind it, the remontoire spring provides almost unvarying energy to the escapement.
