Electronic watch having improved antenna function

An electronic watch, comprising:

• a case having electrical conductivity;
• a cover member attached to the case;
• a hand;
• a hand shaft to which the hand is attached;
• and
• an antenna disposed so as to overlap the cover member in plan view when viewed from a first direction parallel to an axial direction of the hand shaft, the antenna being configured to receive a predetermined radio wave, wherein
• the cover member is made of a material configured to shorten a wavelength of the radio wave,
• the case includes a facing surface facing a side surface of the cover member, the facing surface being located within a predetermined dimension from the side surface,
• the case includes a recessed portion opened to the facing surface and to a front surface of the case, and the recessed portion is provided with a decorative plate having no electrical conductivity, and
• in the first direction, a height dimension from an end portion positioned farthest from the antenna in the facing surface to a farthest portion positioned farthest from the antenna in the cover member is equal to or greater than 1/60 of the wavelength shortened by the cover member.
