To provide a radio controlled timepiece with a thin nondirectional antenna part.

This radio controlled timepiece comprises a first antenna part 1101 formed of a core antenna 1101a, a second antenna part 1102 differed in directivity from the first antenna part 1101 and formed of a coreless loop antenna 1102a, a control circuit 14 for performing a time correction on the basis of a standard time radio signal received by the first antenna part 1101 and the second antenna part 1102, an internal clock 1401, a pointer driving system for driving a pointer wheel having a plurality of reference positions, and an optical detection sensor 140 as a reference position detecting means for detecting the reference position of the pointer gear. The first antenna part 1101 and the second antenna part 1102 are arranged so that the respective directivities of the first antenna part 1101 and the second antenna part 1102 become nondirectional by composition.
