ABSTRACT:
A watch movement construction, in which a circuit board is mounted on one surface of a base plate and has a cutout formed at a position near an outer circumference of the movement construction to accommodate a battery in a position such that a circumferential periphery of the battery is partially aligned with the outer circumference of the movement construction whereas a calendar display member is disposed between another surface of the base plate and a time dial at a position displaced from a central portion of the base plate so that a line passing through a center of the battery, a center of the base plate and a center of the calendar display member makes an obtuse angle whereby the calendar display member and the battery are substantially not in an overlapping state thereby to reduce the thickness of the movement construction.
