  • Publication number: 20220035318
    Abstract: An embodiment of an electronic timepiece includes a cylindrical exterior case, a bezel and a windshield member. In the exterior case, a circuit board is housed. The bezel is formed of a metal material to be ring-shaped, includes an inward flange part that projects from an inner side surface toward a center of the ring-shaped bezel, is arranged on an outer upper side of the exterior case and is electrically connected with the circuit board. The windshield member is formed of a transparent dielectric substance, arranged in the bezel and supported by the inward flange part. The bezel is configured to resonate with a radio wave having a desired frequency by adjustment of at least one of (i) a relative permittivity of the dielectric substance and (ii) an area of an overlap region where the inward flange part and the windshield member overlap each other.
