ABSTRACT:
A radio timepiece is disclosed which receives and decodes a time information signal from a remote transmitter and displays a time information. The timepiece includes a manual time zone switching circuitry deigned to permit use of the timepiece in time zones adjacent to the one in which the transmitter is located, while providing a user-friendly selection and display of the time information. The timepiece includes an electro-optical display providing a cartographical representation of the transmitter time zone and several adjacent time zones. A summing register is provided to manually offset the received time information and actuate a graphic display indicative of the time zone to which the offset time display corresponds. The summing register may be cyclically incremented by a single switch, or incremented, decremented or zeroed by appropriate actuation of two switches.
