ABSTRACT:
A radio wave-standardized electronic timepiece which stores the time at which the timepiece succeeds in reception in conformity with the pattern of living of the user, and on the following days, the timepiece begins to receive from the stored times.
A reception success comparison circuit compares the output signal from a reception success time storage circuit with the output signal from a time information calculation circuit. A reception time comparison circuit compares the output signal from a reception time addition circuit with the output signal from the time information calculation circuit. A reception operation discrimination circuit controls a receiver means according to its input signal. A transfer circuit modifies a time counter and the contents of the reception success time storage circuit according to the output signal from a received data acceptance decision circuit. A display means displays the contents according to the output signal from the time information calculation means.
