Timepiece displaying the current time and including at least first and second display devices for a time-related quantity, the first and second display devices each being driven by a drive mechanism including a drive wheel (), which is itself driven by the movement of the timepiece (), at least the drive wheel () of one of the drive mechanisms carrying a finger () via which the wheel drives the corresponding display device, the timepiece () being characterized in that the finger () is friction fitted onto the drive wheel ().

Timepiece displaying the current time and including at least first and second devices displaying a time-related quantity

The invention relates to a device for correcting a time indication given by a display mechanism for a timepiece of the type comprising a first display member, comprising:

Device for correcting a timepiece display mechanism

The invention concerns an AM/PM display disc (), rotating in one day about an axis of rotation (), including two different juxtaposed surfaces (). It is characterized in that the surfaces are delimited, between a hub () and the periphery () of said disc () by two boundary curves (), each tangential to said periphery () and having a single concavity from said periphery () towards said hub (), the concavities of said curves () having the same direction relative to the direction of rotation (A) of said disc (), and any radial line originating from said axis () intersecting, in succession, one of said two surfaces, then the other, and only passing through one of said curves between said hub () and said periphery (). The invention also concerns an AM/PM display device () including an aperture () and a disc of this type (), characterized in that said axis () is external to said aperture () which is symmetrical relative to an axis of symmetry () passing through said axis of rotation (). The invention also concerns a timepiece incorporating a device () of this type.

AM/PM display device for a timepiece

During normal use, the time indicator () is driven by a mechanism () controlled by the gear train () of the timepiece. This mechanism is arranged for uncoupling the gear train from the indicator when the time-setting member () is actuated, this action causing the indicator to move forward through a step of one hour. The time-setting member includes a push-button () which actuates a device () that in turn acts on said mechanism ().

Watch comprising a mechanism () for driving a device () that displays a time-dependent value, this drive mechanism () itself being driven by the movement of the watch, this watch also having at least one first correction element () acting on the display device () via a clockwork mechanism () of the drive mechanism (), and at least one second correction element () acting directly on the device () that displays the time-dependent value, the watch being characterised in that the drive mechanism () is arranged so as to drive the device () that displays a time-dependent value in both directions when the first correction element () is operated, and so as to be overridden when the second correction element () is operated, acting directly on the device () that displays a time-dependent value.

Timepiece including a two-directional correction mechanism for a device displaying a time related quantity, the display device being actuated by a control lever () itself controlled by a cam (), on which the control lever () abuts, the timepiece being characterized in that it includes a correction device () activated by a control stem () which, in the display device correction phase, via a return lever (), moves the control lever () out of the path of the cam () on which said control lever () normally abuts in the normal operating phase of the timepiece ().
