The invention concerns a device for indicating the state of watch batteries. Said device comprises, in combination: a circuit for determining ( 34 ) at least a physical characteristic of the cell ( 10 ) which varies when it is nearly discharged, a circuit for metering ( 36 ) the power consumed by the watch, a circuit for assessing ( 40 ) the capacity rating of the battery, connected to the determining ( 34 ) and metering ( 36 ) circuits and designed to process data and select the most relevant information derived either from the determining circuit ( 34 ), or from the metering circuit ( 36 ), means for displaying the state of the battery ( 38,40,42 ), and a circuit controlling ( 39 ) the display means.
