A radio-controlled timepiece is controlled by time telegrams emitted by a regional transmitter. When the timepiece is out of the effective range of the regional transmitter, the timepiece is controlled by a local (i.e., close-range) transmitter which transmits time telegrams that have the same frequency and encoding as the time telegrams from the regional transmitter. The local transmitter receives time information from a remote source, such as navigational satellites, or alternatively a time server by way of the internet, in order to create the local time telegrams.
