Abstract
The electronic timepiece movement () is equipped with a motor () including a stator and a permanent magnet rotor () situated in a stator hole, said stator defining at least two magnetic poles () respectively including at least two pole shoes () extending at the periphery of the hole. The motor includes at least one coil () respectively mounted around at least one core (). The two pole shoes and the core form together a first part made of ferromagnetic material formed by or including a single-piece wafer forming both the two pole shoes and the core. An end portion of the core is connected to at least one corresponding pole shoe by a second part, defining a base plate or a main plate made of magnetic material, to which the first part is secured and on which elements of the electronic timepiece movement are at least partially mounted.
