The timepiece has a cylindrical outside case 80 of which at least part is made from a non-conductive material, a dial 11 that displays the time inside the case 80, a drive mechanism 30 that drives displaying the time on the dial 11 inside the case 80, and a C-shaped antenna 40 disposed around the drive mechanism 30 inside the case 80. A crystal 84 covers one of the two openings to the case 80, and a circuit board 25 with a GPS reception unit 26 for radio communication is disposed inside the case 80. The antenna 40 is disposed closer to the crystal 84 than the circuit board 25, and the GPS reception unit 26 is disposed on the back cover 85 side of the circuit board 25.
