Abstract
A timepiece mechanism including an escapement or counting wheel. A balance wheel with two abutting members cooperates with the teeth of the escapement or counting wheel. The action of one abutting member causes the escapement or counting wheel to leave a rest position against the influence of a magnet; the action of the second abutting member furnishes driving energy to the balance wheel.
