ABSTRACT:
A radio-controlled timepiece includes a clock face, a hands assembly mounted for rotation about an axis in front of the clock face, and an alarm setting mechanism. The alarm setting mechanism comprises a minute setting disk which is driven by an hour setting disk. A manually rotatable transparent support disk is mounted in front of the clock face for rotation about the same axis as the hands assembly. The support disk carries a marker which, when the support member is rotated, is moved to indicate a particular hour and minute indicator on the clock face. The support disk is connected to the hour setting disk to rotate the latter which, in turn, rotates the minute setting disk. The support disk is accessible to rotation at the front of the clock. The hour and minute setting disks are preferably connected to an alarm time storage device by means of conductive fingers which are mounted on the disks and which are engageable with concentric conductive strips mounted on a stationary part of the clock.
