ABSTRACT:
A timekeeper equipped with a radio reception device capable of decoding Radio Data System (RDS) information and including a time base, a display for displaying time data supplied by the time base, and an adjustment control for correcting the time data. The radio reception device includes a frequency locking loop for delivering RDS type data derived from a RDS spectrum received on a high-frequency carrier; and a controller which, on the basis of the delivered RDS type data, controls the adjustment control to ensure time setting of the timekeeper. The timekeeper is portable and the radio reception device rejects the spectrum received from a frequency modulated transmitter supplying RDS data, except for the frequency band containing RDS type data.
