    The invention also relates to a timepiece comprising at least one such exhaust mechanism.
    The invention relates to the field of mechanical clocking mechanisms.
    Background of the invention
    [0005] On the clock mechanical control mechanisms comprising escape mechanisms, anchor limiting stops are generally implemented, arranged to cooperate with both a sprung balance and with an escape wheel, at a platinum or anchor deck. Achieving within the required tolerances is expensive.
    To avoid having to seek a compromise between safety and exhaust performance, it is desirable to achieve the limiting surfaces on the component or on which or their implantation is both the most accurate and the least expensive.
    Summary of the invention
    The invention proposes to provide an alternative to the machining of plates and bridges with bores or stone housing positioned with a very high precision, and therefore very expensive, by postponing the manufacture of certain functional surfaces of very high positioning accuracy and shape on other components than the decks and decks, while ensuring the maximum operating safety of the mechanisms involved. The invention thus seeks to exploit the technological possibilities offered by the manufacture of components according to "MEMS", "LIGA" or similar technologies, to produce monobloc timepieces and very high precision, at a cost of acceptable production, and to seek the implantation on other components than the decks and decks of certain surfaces related to the operational safety of a movement, and particularly limiting abutments.
    For this purpose, the invention relates to a watch exhaust mechanism, comprising a plate on which are directly or indirectly attached at least one oscillator cooperating directly or indirectly with at least one escape wheel which has teeth arranged to cooperate with a stop interposed between said oscillator and said escape wheel, characterized in that said exhaust mechanism comprises, at at least some said teeth of said escape wheel, at least one limit stop for limiting angular and / or linear stroke of said stop.
    The invention also relates to a watch movement comprising at least one such escape mechanism.
    The invention also relates to a timepiece comprising at least one such exhaust mechanism.

Advantageously, the peripheral profile of the escape wheel 40 between the teeth 21 is that of a substantially constant radius connecting the foot of a tooth to the head of the next tooth.
    In a particular embodiment, the stop 30 is devoid of any limit stop of its own stroke.
    In a particular embodiment, illustrated in FIGS. 1 and 2, the stop 30 is an anchor comprising vanes 31 arranged to cooperate with the teeth 21 of said escape wheel 20.
