Autonomous control mechanism for a timepiece

An autonomous timepiece control mechanism, comprising:

• on a first side of a main bar or bridge, at least one first control train;
• on a second side of said main bar, at least one second control train;
• and
• at least one control stem, which is moveable relative to said main bar between a plurality of stable positions, in order to pivot, in each said stable position, a single one of said control trains,
• wherein said stem controls the positioning of a pull-out piece, which is fitted to one side of said main bar and moveable relative to a boss of said main bar, in a stable position of the pull-out piece associated with each said stable position of the stem, and in which any movement applied to said stem by the user causes the pivoting movement of either one said first control train, or one said second control train,
• wherein said stem comprises guide means cooperating with complementary guide means of a sliding pinion for the translation of said pinion on said stem and in contact therewith, and for pivoting said sliding pinion integrally with said stem,
• wherein said sliding pinion comprises a first driving means arranged to drive one said first control train and a second driving means arranged to drive one said second control train,
• wherein, fitted to one side of said main bar opposite the side carrying said pull-out piece, said mechanism includes a first lever, arranged to carry a second idle wheel arranged to cooperate with said second driving means to drive, according to the position of said first lever, one said second control train amongst a plurality of said second control trains or second control driving means,
• wherein said first lever is pivotally mounted on a boss of said main bar, and is driven so as to pivot as a result of the longitudinal movement of said stem, directly or indirectly via said sliding pinion, and includes an elastic arm, a free end of which includes bearing surfaces arranged to cooperate in a locking position with a boss of said main bar,
• wherein said main bar carries a first boss arranged to guide the pivoting of a first wheel comprised in one of said second control trains, said first wheel being arranged to mesh with said second idle wheel in a first position of said first lever,
• wherein said main bar carries a second boss arranged to guide the pivoting of a second wheel comprised in one of said second control trains, said second wheel being arranged to mesh with said second idle wheel in a second position of said first lever, and
• further wherein said first lever is inserted between said main bar and said first wheel on the one hand, and said second wheel on the other hand.
