A timepiece mechanism including a deformable rhombus including four coplanar segments pivotally connected in pairs by their vertices, including an input segment adjacent to an output segment, both pivoted about a pivot axis perpendicular to the plane of the rhombus and passing through a first vertex common to the input and output segments and locked in translation in the plane of the rhombus, a lever mounted to pivot about the pivot axis, the lever being kinematically connected in rotation, about the pivot axis, to a second vertex of the rhombus, opposite to the first vertex, a first locking member movable between a first locking position, in which the lever is locked in rotation, and a first unlocking position in which the first locking member does not hinder rotation of the lever, a second locking member movable between a second locking position, in which the second vertex is locked in translation in a radial direction, and a second unlocking position in which the second locking member does not hinder radial movement of the second vertex.

A horological movement with automatic winding, including a plate, a barrel, a cannon-pinion including a minute pipe which supports a minute hand, an hour wheel set including an hour pipe which supports an hour hand, an oscillating weight, arranged on the same side of the plate as the cannon-pinion and the hour wheel set, which includes a central hub, a rim, a heavy sector, a lifting arbor rigidly connected to the central hub and about which the minute pipe and the hour pipe are mounted coaxially, the minute hand and the hour hand being located between the plate and the rim of the rotor.
