Abstract

PURPOSE:To reduce the thickness of the watch and to improve the accuracy of the watch by forming at least the coupling unit of a magnetic core wound with a coil to a stator of a hook and approaching the stator and the magnetic core to one plane. CONSTITUTION:A rotor 22 is contained in a container 23 having bearings, the rotor unit is formed as an independent unit, press-fitted into the stator 16, and the motor unit is formed as an independent unit. The stator unit is formed to be isolated from the stator coil unit 24, the coupling unit of the stator 16 to the stator coil is formed of a hook, and the hook is superposed and fixed to the base plate 27 via anchoring screw 25. The rotor pinion 12 formed on the rotor 22 is engaged with a wheel train journaled between a predetermined plate and the base plate.
