ABSTRACT:
A radio wave timepiece has a movement having a circular main plate, a plastic train wheel bridge that supports a fourth wheel & pinion, and a ferrite antenna. The antenna is disposed in a recess formed by the main plate and is curved along an outer periphery of the circular main plate. A plastic antenna cover at the back side of the movement covers the recess, and part of the plastic antenna cover constitutes a plastic seat on which seats the train wheel bridge. The plastic seat functions as a hand pushing receive seat during attachment of time-indicating hands to the movement. A metal pin is attached to a stepped through-hole in the antenna cover at a given distance from an end of a fourth stem of the fourth wheel & pinion. A plurality of push up projections, one on the plastic seat and the others on the main plate, project toward the back side of the movement to support the main plate and plastic seat during attachment of the time-indicating hands.
