Abstract
A thin electronic timepiece can receive satellite signals and standard time signals. An electronic timepiece has a planar antenna for receiving satellite signals, a bar antenna for receiving standard time signals, a time display unit with a plurality of hands, a plurality of motors for driving the hands, a battery, and a timepiece case. In a plan view of the electronic timepiece, the planar antenna, bar antenna, and battery are disposed to positions not mutually superimposed; the plural motors are disposed inside the timepiece case at positions not superimposed in plan view with the planar antenna and bar antenna; and at least one of the plural motors is disposed superimposed in plan view with the battery inside the timepiece case.
