Abstract
A timepiece movement is disclosed in which a hand-setting stem is oriented in the longitudinal direction of the movement and that includes a relatively short portion inside the movement. A pull-out piece may be mounted pivotably on the frame of the movement and carry a pivoting member, interacting with the frame, and also a linking member designed to interact with the stem to limit the translational movement of the stem. The pivoting member, preferably produced in the form of a pull-out screw, may include first and second pivots arranged on either side of the pull-out piece and engaged in the frame. Preferably, the stem may be engaged, permanently catching, with a crown pinion to form an assembly that may also include first and second pivots arranged on either side of the crown pinion and engaged in the frame.
Claims20
A timepiece movement comprising:
- a frame comprising a bottom plate;
- a time display mechanism;
- a hand-setting mechanism comprising a hand-setting stem, movably mounted on the frame and configured to translate along a first axis between at least two axial positions and to rotate about the first axis, and capable of being operatively connected to the time display mechanism;
- and
- first and second support elements distinct from the bottom plate and secured to the frame, between which there is a crown pinion integral in rotation with the hand-setting stem, the first and second support elements defining respective first and second pivots for an assembly formed by the crown pinion and the hand-setting stem.
A timepiece part including a case closed by a glass and in which is housed a movement comprising:
- a frame comprising a bottom plate;
- a time display mechanism;
- a hand-setting mechanism comprising a hand-setting stem, movably mounted on the frame and configured to translate along a first axis between at least two axial positions and to rotate about the axis, capable of being operatively connected to the time display mechanism;
- first and second support elements distinct from the bottom plate and secured to the frame, between which there is a crown pinion integral in rotation with the hand-setting stem, the first and second support elements defining respective first and second pivots for an assembly formed by the crown pinion and the hand-setting stem;
- the movement being arranged so the frame has a median portion, supporting a finishing-works assembly and a time display, delimited by two end portions connected to the case, the median portion having a length oriented on a six o'clock and midday axis and being at least three times as large as its width;
- and
- a hand-setting crown being arranged at one end of the hand-setting stem located at one of six o'clock or midday.
