Abstract

Device for indicating the duration of an electric battery in an electric clock, including a light emitting element having a predetermined threshold voltage, and means for applying a pulse having a predetermined frequency to this element for illuminating it in an intermittent manner, said impulse being obtained from electronic circuits operated by said electric battery, said element having an electrical characteristic such that said element stops emitting the light to signal the moment in which said electric battery has to be changed, when said electric battery is has exhausted to the point that its electric power decreases below said threshold voltage.
