Lepine Movement
An extremely thin bar movement. Lepine introduced his improvements in 1776 and they consisted of the suppression of the pillar plate, the fuzee and chain and one of the supports to the barrel arbor. The Lepine family resided at Ferney, near Geneva, where Voltaire established a watch factory. Brequet improved on the Lepine system by causing the mainspring to be wound up at the back of the watch through the dome, instead of by a square through the face of the dial.
