Lépine Caliber (Movement)

This type of caliber is named after its inventor Jean-Antoine Lépine (1720-1814). Jean-Antoine Lépine was an influential French watchmaker, and clockmaker to Louis XV, Louis XVI, and Napoleon I.

The distinguishing feature of this caliber is that, by removal of the fusee and its chain, replacing the top plate and pillars with bridges, hence all moving parts were maintained by independent bridges, therefore the thickness of watches was reduced.

In a pocket watch, the Lépine or open-ace caliber denotes a structure in which the seconds hand is positioned in line with the winding-stem, as opposed to the hunter caliber in which the seconds hand is at a right angle to the winding stem.
