<p>The timepiece has a striking work stopping cam (61) in desmodromic connection with an arbor and a drum of a barrel with an angular ratio chosen such that its total displacement angle does not exceed 360 degrees. Locking levers (79, 80) occupy a position, in which a clutch lever moves to a disengaged position when it is liberated by a triggering lever (48), and another position in which the clutch lever is retained in an engaged position by the locking levers. The locking levers have protrusions (79a, 79b) alternatively gripping the cam to displace it between the two positions.</p> |
