A timepiece drive mechanism including a structure on which pivots an arm subjected to the return torque of a first energy source, this arm carrying a planetary gear including a wheel, a second energy source subjecting to a return torque a third wheel set on which the wheel rolls, under the action of the first energy source, the structure carries a stop device cooperating with complementary a stop device of the third wheel set to hold the latter in position, which are uncouplable under the action of uncoupling control device of the arm at the end of the forward angular travel of the arm to allow the third wheel set to pivot in a single direction under the action of the second energy source, causing a backward rotation of the arm to its start-of-angular-travel position.

Timepiece drive mechanism

A horological movement including a tourbillon or karussel frame carried by an arm subjected to the torque of a first energy source, and a second energy source driving a frame pitch mobile driving the frame, and, for periodically controlling a retrograde movement of the arm, a release mobile connected to the second energy source and cooperating at a pallet-stone with an interrupted cam that a cam mobile kinematically connected to this arm includes, to allow advancing the arm in a direct direction as long as the pallet-stone is resting on the cam, and to control a rapid retrograde return of this arm during a drop of the pallet-stone between two of its successive support surfaces on the cam.

Timepiece retrograde tourbillon or karussel

A timepiece movement with a regulating member which is a tourbillon or carousel, also known as a karussel, and including a drive mechanism, with a pivoting arm subjected to the restoring torque of a first energy source and carrying a mechanism comprising a wheel, a second energy source that subjects to a restoring torque a third wheel set on which the wheel rolls, under the action of the first energy source, the structure carries stop means cooperating with complementary stop means of the third wheel set to hold the latter in position, which are uncouple-able under the action of uncoupling control means of the arm at the end of the forward angular travel of the arm to allow the third wheel set to pivot in a single direction under the action of the second energy source, causing a backward rotation of the arm to the start of its angular travel.

Retrograde tourbillon or karussel for timepieces

A presentation case is arranged for receiving an electromechanical watch provided with a stepping motor for driving the watch hands. The presentation case includes a box with a support for receiving the watch, a system for detecting the position of the hands, and a device for resetting the watch connected to the hand position detection system. The resetting device resets the watch based on information received from the hand position detection system and a time reference when the watch is placed on the receiving support. The resetting device includes a driver for the stepping motor of the electromechanical watch, which is arranged inside the presentation case facing the stepping motor, when the watch is placed on the receiving support, and causes a rotation of the stepping motor by inductive coupling.

Presentation case for an electromechanical watch and assembly comprising the same

A timepiece case, including a seat which guides inside it a push-piece for supplying energy, including a control member which can be operated with pressure against resilient return device and which is integral with driving device, the push-piece or the case including a flat cam track, the case or the push-piece including a pivot about which an arm carrying a pin following the profile of this track pivots, which track includes elbows directed towards the pivot and defining stable positions of the pin and ramps arranged so that any pressure applied on the control member when it is in the rest position causes the pin to come out of its stable position and to travel, under the action of the resilient return device, towards another stable position.

Timepiece case with push-piece

A winding device on a structure of a movement or watch case, including a telescopic push-piece, independent of the control stem, driving a rack for winding a barrel, and including, between a pipe fixed to the case and an operating head, first elastic return device tending to move the head away from the pipe, this head being capable of occupying an angular, longitudinal locking position corresponding to a rest position, or an angular position of freedom allowing axial mobility, or a stop position wherein it has one degree of freedom, this rack, which is movable against second elastic return device, cooperates with a winding wheel set meshing with an intermediate rack actuated by a return spring of the second elastic return device.
