International ClassG04C 011/02Foreign Application Priority Data1988-12-20 DEAbstractAn autonomous radio timepiece with a receiver for receiving time telegram information to be decoded and a reset switch for the restarting the reception, decoding and display functions. The timepiece is structured so that manual actuation is still be possible, and erroneous actions affecting the processor relative to the execution of time telegram decoding and the control of time derived functions are prevented. For this purpose, optionally in addition to the conventional reset switch installed in a covered manner, a separate receiver switch is provided, whereby the receiver may be actuated temporarily and optionally the time display unit then reset into a reference position. If the receiver is not provided with a usable time information within a predetermined period time, the time display unit is reset to the value of the time register in order to display the time incremented in the register in a normal time keeping manner or the time instantaneously verified by radio, without affecting other time derived functions, such as an alarm emission program, by such intermittent actuation of the receiver. Thus, the time which has been incremented in said register in a time keeping manner is displayed.Other References
