    Abstract: The winding device includes a motorization device for driving a watch holder carrying at least one automatic watch with a mobile oscillating mass, and a measuring device for measuring the variation in the resistive torque opposed to the motorization device by the watch holder equipped with watches, depending on the degree of winding of the watches. The measuring device includes a speed measuring device to determine the speed and/or the variation in the speed of the motorization device, and/or include a torque measuring device to determine the value of the torque and/or the variation in the torque at the watch holder, and/or include a current measuring device to determine the value of the current and/or the variation in the current of an electric motor of the motorization device.

    CPC classification number: G04B13/02 F16H49/005

    Abstract: A mechanism (1) including a magnetic gear (2) including a first wheel (6A) and a second wheel (6B), the first wheel (6A) being provided with first permanent magnetic poles (7) forming first magnetic toothing (8), the second wheel (6B) being provided with a second magnetic toothing (10) made of a ferromagnetic material, the first wheel (6A) and the second wheel (6B) being arranged such that the first magnetic toothing has a first magnetic coupling with the second magnetic toothing (10). The gear (2) has a third wheel (6C) having second permanent magnetic poles (9) which form a third magnetic toothing (12), the third wheel and the second wheel being arranged such that the third magnetic toothing has a second magnetic coupling with the second magnetic toothing; the magnetic gear (2) being arranged such that the first and third wheels are each angularly positioned in a specific manner.

    Abstract: An arrangement for the holding and vibration transmission of an acoustic radiating membrane (10) in a striking or musical watch (1) case (2). The case includes at least one crystal (3) mounted on a middle (4) and a back (5) mounted on a side opposite the middle. The acoustic radiating membrane is held in a portion of the watch case, such as the middle by at least one connection part (12) disposed between a peripheral rim of the membrane or an edge element (11) of the membrane and the middle by acting for the holding of the membrane in a direction parallel to the plane of the watch. The connection part may be a screw screwed into a threaded opening (14) of the middle and coming into contact with the edge element of the membrane.
