Abstract
A radio-controlled timepiece contains a mechanism for the detection and correction of a hands setting. The mechanism includes a sender and a receiver for sending and receiving, respectively, a radiation beam. A hands setting mechanism includes an hour wheel, a minute wheel, and a seconds wheel, each possessing an aperture therethrough. The hour wheel has a front mirror located proximate the beam sender for reflecting a beam to the receiver. The front mirror has an interruption defined by the aperture of the hour disk in order to pass the beam through that aperture to a rear mirror disposed remote from the sender, such that a beam reflects from the rear mirror only after passing through aligned apertures in the disks. The hour wheel is movable independently of the minute wheel and seconds wheel, and the minute wheel and seconds wheel are rotatably interconnected.
