Embodiment Construction

[0054] See below Figure 1 to Figure 6 A first embodiment of the timer 200 is described. For example, timepieces are watches, especially wristwatches. The timepiece includes movement 100 . The movement is preferably a mechanical automatic movement. The movement includes a frame 4, a mainspring 7, a gear train and a self-winding or self-winding device. The automatic winding device can be Figure 8 Depicted self-winding module M'. Throughout this text, "self-winding device" or "self-winding device" refers to the transmission system 300, 300' for automatically winding the movement or the transmission system for automatically winding the mainspring 7, 7' of the movement. part. This part of the transmission system comprises at least one oscillating body 8, the mechanical energy of which is used to wind the mainspring.

[0055] Preferably, the automatic winder includes reversing wheels 11 , 12 . Therefore, the self-winder is preferably bidirectional, which means that the rat...

Abstract

A system (10) comprising: pawl means (110) for a first wheel (6) of a first part (301) of a transmission (300) for winding a mainspring (7); clutch means (120) for connecting the second part (302) of the transmission system (300) winding the mainspring (7) with the first part (301) of the transmission system (300) winding the mainspring (7) and a coupling device (130) for coupling the pawl device and the clutch device, in particular a device (130) for coupling the operating states of the pawl device and the clutch device.

Description

technical field [0001] The present invention relates to a timepiece system. The invention also relates to a timepiece movement comprising such a system. The invention also relates to a timepiece comprising such a system or such a movement. The invention also relates to a method of operating such a system, such a movement or such a timepiece. The invention also relates to a winding drive system for a mainspring. The invention also relates to a timepiece movement comprising such a transmission system. The invention also relates to a timepiece comprising such a transmission system or such a movement. Background technique [0002] The mainspring in a hand-wound chronograph or self-winding chronograph is usually kept taut by a pawl designed to cooperate with a ratchet mounted squarely on the arbor or in a case provided with at least two barrels. In the case of the movement, it cooperates directly with the mainspring drum. More specifically, the pawl fixes the ratchet in the...
