Beschreibung
Zusammenfassung:	An electronic timepiece has a tubular outside case of which at least part is a conductive material, a transparent crystal, a dial housed in the outside case, an annular antenna body disposed around the dial, a feed part that feeds the antenna body, and a dial ring made of a non-conductive material covering the antenna body. The antenna body includes an annular dielectric base, and an arc-shaped fed element fed by the feed part, an annular parasitic element disposed between the dial ring and crystal, which receives circularly polarized waves.
