Abstract
A clock includes a housing with a receiving space and a slit extending along a portion of a surrounding wall thereof in a plane. A clock mechanism is fixed on a central area of the receiving space, and has a spindle with an axis normal to the plane. An elongated positioning member includes an abutment portion which is disposed above the clock mechanism and which has a through hole for passage of the spindle therethrough for mounting time indicating hands thereon, and an anchoring portion which extends from the abutment portion in a radial direction relative to the axis. The anchoring portion has right and left lateral sides opposite to each other and parallel to the radial direction. A dial plate is insertable into the receiving space via the slit along the plane, and has an inner periphery extending inwardly in the radial direction to confine a notch with two inner edge portions opposite to each other so as to mate respectively with the right and left lateral sides.
