Timing wheel set (130) 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 said function, and further arranged to cooperate with a means (600) of coupling said function. It includes a timing hook (141) arranged to be operated by said coupling means (600) in order to be placed in cooperation with a ratchet (133) or to be released from said ratchet (133), said ratchet (133) being pivotally mounted on an arbour coaxially to a timing wheel (132) towards which it is pivoted back by return means (135), said timing wheel (132) being arranged to cooperate, directly or indirectly, with said release element.
