Abstract
A timepiece incorporating a mechanical movement and including a device for setting its rate, including a rotationally mobile part and a setting mobile (4) controlling the angular position of the rotationally mobile part. The setting device includes a lever (5) fitted with a linking train (6) and by a actuator button, between an uncoupled position and a coupled position. The setting mobile is kinematically joined, via the linking train (6), to a mobile (7) on a correction device, including a control arbor fitted with a crown enabling the mobile to be actuated, or to a drive mobile of an indicator which can be driven by the correction device when correcting the data displayed by the indicator to set the rate of the timepiece by actuating the button.
Claims8
A timepiece comprising:
- a mechanical movement fitted with a regulating organ formed by an inertial mass (1) and a balance spring (2);
- a device for correcting data displayed by at least one indicator on a display device comprised in the timepiece, this correction device being controlled by a control arbor fitted with a crown that can be translationally and rotationally actuated by a user;
- and
- a device for setting the rate of the timepiece, comprising a rotationally mobile part (3), defining at least one physical property of the balance spring, and a setting mobile (4) capable of controlling the angular position of the rotationally mobile part, so as to be able to act on the balance spring (2) to change the frequency of the regulating organ according to the angular position of the rotationally mobile part;
- wherein the setting device further comprises a lever (5) fitted with at least part of a linking train (6) and capable of being rotated by a button, which can be actuated by the user, between an uncoupled position and a coupled position, in which the setting mobile (4) is kinematically joined, via the linking train, to a mobile (7) on the correction device or on a device for driving said indicator, the mobile being capable of being driven by the control arbor once the control arbor has been moved to a given axial correction position, so as to enable the rate of the timepiece to be set by pressing on the button, thus moving the lever to an coupled position, and by translating the crown, in order to move the control arbor to the given axial correction position, and then by rotating the crown.
