ABSTRACT:
A autonomous radio timepiece (11), in particular in the form of a small travel clock or a wristwatch, is designed to operate for an extended period of time with a small battery, and to provide a reliable time display when traveling outside the reception range of a transmitter of coded time telegrams set for a certain geographical time zone. The timepiece casing (20) is equipped with a multifuncton switching device (21) and an associated decoder (23), which evaluates the combination of the momentary actuation of push buttons (22). It is thus possible by means of the switching device (21) to switch into a power saving storage state if the timepiece is not in use, and to return to normal operations.
