Abstract: An escapement mechanism including a dual-forked lever having a pivot suitable for movement of the lever between a first pivot limit and a second pivot limit, and at least two rounded follower elements spaced from the pivot and at a predetermined distance from each other. At least one of the follower elements is mounted on each fork of the lever and each follower element lacks a locking face. At least one escape wheel has an outer periphery defining at least a first plurality of cam elements suitable to slidably contact and drive the rounded follower elements, and each cam element lacks a locking surface where contact is made with the follower elements.
