Abstract (en)
[origin: EP2241944A2] The mechanism has a snail cam (3) driven in rotation by an axle (4), a needle cooperating with a graduation. The snail cam has a slot (20) that is extended on an arc portion comprised between 30 degrees and 90 degrees, where the slot separates a central body from the snail cam. An end of a terminal part (21) forms a part with a large height (H) of the snail cam. A ratchet (8) cooperates with a tooth under the action of the ratchet action.
