Abstract:
1. An electronic timepiece movement having an electromagnetic motor and an analogue display driven by said electromagnetic motor, said motor being formed of a stator and of a rotor housed in a frame made of non-magnetic material mounted in an aperture in the stator, the rotor including a permanent magnet and having at both ends, along the axis of rotation thereof, respectively two pivots which are respectively pivotally mounted in two bearings respectively arranged in a first part and a second part of said frame, said frame having a lateral aperture; wherein said lateral aperture has a maximum width at least equal to the maximum diameter of said rotor, and wherein the first part or the first and second parts of the frame is/are elastically deformable along the direction of said axis of rotation, said first part or said first and second parts together having sufficient elastic deformation capacity to allow the rotor to be assembled in the frame through the lateral aperture therein, in particular to allow the insertion of the two rotor pivots into the two respective bearings.
