Remontoire

For the Revelation Space character, see Characters in Revelation Space#Remontoire.

In horology, a remontoire is a secondary winding mechanism that is periodically re-wound from the main source of energy, such as a mainspring. In precision clocks it is used to regulate the force that drives the clock\'s timekeeping mechanism. In turret clocks it serves to separate the large forces needed to drive the hands from the modest forces needed to drive the escapement which keeps the pendulum swinging.

Winding mechanism used in automobile clocks

Before the common use of electronic clocks in automobiles a low energy power spring would be wound every few minutes by the short motion action of a solenoid, powered by the vehicle\'s service battery and activated by a simple switch upon low power spring tension. Such clocks were, however, notoriously inaccurate, typically being made as cheaply as possible.
