1. A timepiece comprising a supporting structure and a generator formed of a rotor, provided with at least one magnet and mounted to pivot in the supporting structure, and of a stator composed of two coils and forming, with an electronic circuit, an electronic module which is arranged so as to be able to be mounted in the supporting structure after mounting the supporting structure with the rotor pivoted therein; wherein the electronic module comprises a support for the two coils having a first part forming an articulation with a first element of the supporting structure, the first part and the first element being arranged so that said first part or/and said first element can undergo an elastic deformation allowing them to be assembled, in a removable manner, to form said articulation by laterally introducing, by pressure, the first part into the first element or the first element into the first part; and wherein the timepiece is arranged so that, during a lateral mounting of the electronic module in the supporting structure preassembled with the rotor, the first part and the first element can be assembled to form said articulation, which then allows a rotation of the electronic module, around an axis of rotation defined by said articulation and parallel to an axis of rotation of the rotor, from a first angular position, wherein said electronic module is located directly after forming the articulation, to a second angular position to bring at least one of the two coils closer to the axis of rotation of the rotor, so that these two coils are each located in a functional position substantially at the same distance from the axis of rotation of the rotor, the electronic module being held in the second angular position by a fastening system which is arranged to be able to block the articulation in said second angular position.
