Abstract: A mechanism including a magnetic gear including a first wheel, a second wheel and a third wheel. The first wheel is provided with permanent magnetic poles which are arranged so as to form the magnetised teeth of a first magnetic toothing. The second wheel and the third wheel are provided with teeth made of a soft ferromagnetic material respectively defining a second magnetic toothing and a third magnetic toothing, each with a number of teeth that is greater than that of the first magnetic toothing and having a magnetic coupling with this first magnetic toothing. The second magnetic toothing is directly coupled with the first magnetic toothing and with the third magnetic toothing thanks to the magnetic fluxes provided by the magnetised teeth of the first toothing and the teeth of the second magnetic toothing are magnetically separated from one another.

Abstract: A device is disclosed for verifying the state of a watch and resetting it to the correct time. In a case of the device, a watch can be disposed on a watch support, which can be moved from a position without measurement to a measurement position in a vision system, or vice versa. In a position without measurement, the watch on its support can be observed from the outside of the case of the device through at least one electronic shutter activated or an optical valve activated to be in a transparent state, whereas in the measurement position, the electronic shutter or the optical valve is deactivated to be made opaque.

Abstract: An embedded winding mechanism for a watch or an automatic watch. The watch or the automatic watch including a mainspring wheel configured to wind a mainspring, at least one electric motor and at least one oscillating weight. The embedded winding mechanism including at least one primary ratchet gear configured to mesh the mainspring wheel of the watch or an automatic watch when the at least one oscillating weight meshes the at least one primary ratchet gear, and at least one secondary ratchet gear configured to actuate the mainspring wheel of the watch or an automatic watch when the at least one electric motor actuates the at least one secondary ratchet gear.
