A clockworks, a timepiece and a method for operating a timepiece. The timepiece comprises a housing providing a face, the face having indicators corresponding to respective time increments, a plurality of hands rotatably supported on the face, the plurality of hands being rotatably positionable relative to the indicators to indicate a time, one of the plurality of hands being a sweep hand, and the clockworks supported by the housing. The clockworks includes a drive mechanism supported by the housing and connectable to the plurality of hands to rotatably drive the plurality of hands, the drive mechanism being connectable to a power source operable to power the drive mechanism, a time register to store information corresponding to the time indicated by the plurality of hands, a switch member connected with the time register, the switch being operated when the sweep hand rotates by one of the indicators and when the sweep hand rotates by an other one of the plurality of hands to provide the information to the time register corresponding to the time indicated by the plurality of hands, means for receiving a broadcast time signal, means for comparing information corresponding to a broadcast time represented by the broadcast time signal to the information corresponding to the time indicated by the plurality of hands, and means for synchronizing the time indicated by the plurality of hands to the broadcast time.
