Abstract

A wristwatch stepping motor comprises mounted on a support plate a rotor, an armature consisting of two portions each with a pole structure disposed at opposite sides of the rotor and a coil mounted on a coil core which is integral with one of the armature portions, the other armature portion being spaced from the coil core and being so mounted that its one end is in abutment with the free end of the coil core and the pole structures of both armature portions together with the rotor are arranged outside the area around the coil core, both armature portions being located by collars and sleeves projecting from the support plate to facilitate automatic assembly of the motor.
