Abstract
An analog electronic timepiece for rotating hands by a motor through a wheel train has the structure that only an hour hand wheel is disposed between a main plate and a dial. The hand wheel is supported by a pin shaped projection of the main plate and a support plate fixed to the rear side of the main plate. A dial is also fixed to the rear side of the main plate through the support plate, or directly fixed to the support plate. The support plate is made of a material having a high magnetic permeability and extended to the both ends of a magnetic core of a motor assembly so that the timepiece is not easily affected by external magnetic disturbance.
