Abstract

PURPOSE:To provide a portable electronic watch provided with a receiving function of good efficiency by floating the external case of the watch body from power source line and providing a function as a primary antenna. CONSTITUTION:An oscillation circuit part 5, frequency dividing circuit part 6 and display circuit part 7 are analogous to the constitution of those of conventional electronic watches. A receiving circuit consisting of an antenna 2 and a receiving circuit part 3 receives the defining signal transmitted from the outside and is connected to a correction pulse forming part 4. The correction pulse forming part 4 controls the frequency dividing circuit part 6 of the watch circuit and corrects the time of the watch body at the accurate time. The receiving circuit part 3, correction pulse forming part 4, oscillation circuit part 5, frequency dividing circuit part 6, display circuit part 7 and provided within the shield case 8 connected to the earth line of the power source. since an external case 1 is not connected to the power source line, it is held afloat from the earth line of the watch body.
