The calibre was quickly adopted throughout France and today its basic design is what characterizes all mechanical watches. It is important to note that the term "Lépine" can refer to both the calibre itself or a type of pocket watch with a flat, open-faced case in which the second wheel is placed in the axis of the winder shaft and the crown positioned at XII, in opposition to the savonete (or hunter-case) watch where the second wheel and winder shaft are placed on perpendicular axes and the crown at III. This design has been known within the watch industry as the Lépine style ever since.
