Abstract
In an electronic watch powered by a battery, magnetic shield members made of an antimagnetic material are disposed in a watch movement to prevent the magnetization of the watch movement under the influence of a magnetic field outside of the watch, whereby watch hands continuously operate to indicate a correct time. The watch movement includes a bridge and a base plate, and the magnetic shield members are respectively mounted in a recess in the base plate and carried by the bridge so as not to contribute to a thickness of the watch movement.
