Radio controlled timepiece

摘要

A radio controlled timepiece includes: a radio wave receiving section (12) which outputs a time code signal; an indicator display section (71) which performs a display regarding a reception condition; a level change detecting section (20) which detects a change of a signal level of the time code signal in a detection interval in a period of 1 second; an indicator control section (20) which controls a content of the display based on a number of times that the change of the detected signal level appears; and an interval setting section (20, 22b) which specifies the detection interval as a whole interval of the period of 1 second during a detecting process of a synchronization point in the time code signal every 1 second, and narrows the detection interval to be a certain interval within the period of 1 second after a detection of the synchronization point every 1 second.
