Abstract
Timing wheel set for a timepiece mechanism, for limiting the duration of operation of a function after the start thereof, arranged to cooperate with a release element, the start of motion of which initiates the release of the function, and further arranged to cooperate with a device for coupling the function. It includes a timing hook arranged to be operated by the coupling device in order to be placed in cooperation with a ratchet or to be released from the ratchet, the ratchet being pivotally mounted on an arbour coaxially to a timing wheel towards which it is pivoted back by return mechanism, the timing wheel being arranged to cooperate, directly or indirectly, with the release element.
