ABSTRACT:
An autonomous radio timepiece (1), in particular small, portable timepiece such as a travel alarm clock or a wrist watch includes a display (25) of the prevailing radio field intensity. The display (25) is capable of simultaneously signaling the actuation of a receiver (14) for the decoding of absolute time information and is conveniently combined, in the form of a bar graph, with day indicator flags adjacent a day-of-the-week display (26). When operating outside the time zone for which the transmitter emits the coded absolute time information, the time piece may be manually switched to the instantaneously prevailing time zone. The number of time zone changes may be entered and displayed, or the prevailing hour (H) of the time zone involved is entered, from which an electro-mechanical time display (18) then continues to advance.
