Abstract: An electronic timepiece includes an exterior case, one or more circuits housed in the exterior case, wherein the one or more circuits are configured to process a signal in a radio wave having a predetermined frequency, and a bezel disposed on an outer side of the exterior case, wherein the bezel comprises a metal portion configured to resonate with the radio wave, and wherein the metal portion of the bezel is electrically connected to the one or more circuits to transmit the signal in the radio wave received by the metal portion of the bezel to the one or more circuits. A method for assembling the electronic timepiece is further provided.

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.
