Abstract
An analog-type electronic watch with an electrical generating apparatus, this watch having a load compensation function means, and completing avoiding the adverse influence of magnetic noise which accompanying electrical generation operation. This watch has an electrical generator which operates intermittently, an electrical generation detection means which detects electrical generation by the electrical generator based on a prescribed relationship to the operation of a drive judging means, and a control means which, when the driving judging means detects electrical generation by the electrical generator, supplies a compensation drive pulse to a drive circuit, regardless of the judgment results of the driving judging means.
