摘要： An electronic watch including a watch circuit and display is provided which additionally includes an automatic time indication modifier. The modifier comprises a receiver, a filter for passing only that component of the signal from the receiver which has the same frequency as a time announcement signal, a pulse height discriminator for converting an output signal of the filter into a bi-level signal in accordance with the magnitude of the output signal above a threshold level, a time announcement pattern discrimination circuit responsive to the bi-level signal from the discriminator to determine the presence of a time announcement pattern on the basis of the duration of and the time interval between the bi-level signals, and a "seconds" indication modifying and control circuit for modifying a "seconds" indication of the watch in response to an output signal from the discrimination circuit.
