Control mechanism for a timepiece movement, including, in a housing in a main plate, a control stem that is movable in a longitudinal direction and including a groove cooperating with a stud comprised in a pull-out piece for actuating the pivoting of the pull-out piece on the main plate, this pull-out piece is held in position by a jumper spring, and the mechanism including a bridge cooperating with the main plate to confine the stem, and this bridge includes a housing in which there is a movable limiter piston, arranged to abut on one end of a trunnion comprised in the pull-out piece under the application of a force in a transverse direction substantially orthogonal to the longitudinal direction, to allow the release of the stem after a given travel of the limiter piston.

Control mechanism with a securely removable stem

A corrector () for a function indicator () for a movement () including: a first control mechanism () for a first function, in a let down () or wound () position, a second control mechanism () for a second function, in a let down position () or release control position () followed by a return to the preceding position, and a display indicator () for a third function. First mobile part () driven by the first control mechanism () occupies a letting down ()/winding () position, when the mechanism occupies the let down ()/wound () position. Second mobile part () actuating the indicator () is driven by the second control mechanism () changing into the control position () when the first mobile part () is in a winding position () and cooperates with this latter in the letting down position (), under the action of return mechanism ().

Quick corrector for a time related magnitude indicator for a timepiece

The timepiece includes means for adjusting the shake of a rotating part or wheel set, in particular a balance one bearing of which is arranged in a bar (). This bar comprises a base () associated with a adjusting screw () one end () of which rests on the bottom plate. Rotating this adjusting screw varies the distance between the base and the bottom plate (). The center of the adjusting screw is pierced for the passage of a tightening screw () for fixing the bar to the bottom plate. This adjusting screw is arranged in a hole () passing through the base () and can be rotated through the hole from the top face () of the bar in order to adjust the balance shake.
