ABSTRACT:
This mechanism is intended for time setting of an analog mechanical display in a timepiece. It comprises a manually operable crowned stem (1) arranged to be toggled into at least two axial positions the active one of which is drawn-out relative to the neutral pushed-in position. The stem is provided with a toothed pinion (3) which meshes with an axially displaceable pinion (6). Such pinions are placed side-by-side and a mechanism including a trigger piece (9), a rocking lever (10) and a slider (21) slaves the axially displaceable pinion to the stem. The arrangement is compact and readily integrated into a thin timepiece.
