PROBLEM TO BE SOLVED: To provide an electronic wrist watch having good decorativeness and wearability by disposing a solar cell and an antenna in the rear side of a dial plate while maintaining sure reception of microwave.SOLUTION: A wrist watch 3 with GPS includes a dial plate 11 for displaying time information on a front surface 11a thereof, a solar cell 22, and a GPS antenna 27. The solar cell 22 receives light passing through the dial plate 11 and produces electrical power by photovoltaic generation. The GPS antenna 27 is disposed so that at least a part of the signal receiving surface 27a opposes at least a part of the back surface 11b of the dial plate 11, and receives microwave signals passing through the dial plate 11. The wrist watch 3 with GPS is configured so that the solar cell 22 is not disposed in the space between the back surface 11b of the dial plate 11 and the signal receiving surface 27a of the GPS antenna 27. |
