Abstract: A timepiece includes a movement and a current-time ringing mechanism that includes: an hour cam (40) for providing information on the hour of the current time to an hour sampler, quarter cam (28) for providing information on the quarters of the current time to a quarter sampler, a minute cam (22) for providing information on the minutes of the current time to a minute sampler, wherein the cams are adapted to be driven by the movement, the quarter cam (28) and the minute cam (22) being pivotally mounted and being free relative to each other, and the minute cam (22) including a snail including a single row of 60/N stages and being adapted to be driven by the movement at N revolutions per hour.

Abstract: A timepiece, including: a power source; a control member (32) movable between a first and second position defined by a power reserve mechanism; an additional mechanism; a triggering nose (16), the movement of which triggers the additional mechanism; and a triggering member (10) to be actuated for interaction with the triggering nose (6) for triggering the additional mechanism. The triggering member is capable of assuming a first position in which it engages with the triggering nose (16), and a second position in which it cannot engage with the triggering nose (16). The control member (32) is arranged so as to engage with the triggering member (10) and to move into the first or second position depending on whether the control member (32) is in the first or second position.

Abstract: A movement for a timepiece having a retrograde display member displaying at least one time division, includes a going train, elements for driving the display member including a wheel unit driven by the going train and carrying a first cam sharing the same axis of rotation. The movement also includes a rocker supporting a probe held against the edge of the first cam by deformable elastic elements undergoing a deformation of variable amplitude. This results in the application of a corresponding force on the rocker in proportion to the distance between the probe and the axis of rotation of the first cam. The movement also includes drive members to connect the rocker to a retrograde display member. A force-regulating device is interposed between the elastic elements and the rocker.

Abstract: A ringing mechanism includes: a power source (12), a speed regulator (14), a ringing device, and a gear (10) connecting the power source (12) to the regulator (14) on the one hand and to the device on the other hand. The mechanism further includes a speed adjustor (16) and control element interacting with the speed adjustor (16) in order to change the driving speed of the ringing device.

Abstract: A timepiece includes a case with a rotating bezel, time display elements, and a hand-setting mechanism which includes a hand-setting stem housed entirely inside the case and movable between at least a first axial position and a second or hand-setting axial position. Connection elements capable of enabling a kinematic connection to be established between the rotating bezel and the hand-setting stem are provided so that turning the rotating bezel turns the hand-setting stem. The timepiece also includes a lever for external control, which pivots on the case via a connecting stem and which has an end portion movable between at least a first position and a second or hand-setting position. A control mechanism is provided to act on the hand-setting stem and move it from one axial position to the other in response to action on the control lever.

Abstract: An oscillating weight for an automatic watch is arranged to carry a bearing defining an axis of rotation (A—A) and is intended to be mounted on the frame of the watch. The mass member of the weight has a center of gravity (G) shifted with respect to the axis of rotation. In this weight, this mass member includes two parts that can be moved one (10, 18) in relation to the other (24), and arranged such that their relative movement causes a radial movement of the center of gravity (G) of the mass member. The mass member also has a securing device (13, 14, 16b) cooperating with the first and second parts, capable of occupying a first state in which the parts can be moved with reference to each other, and a second state in which the parts are rigidly secured to each other.
