Abstract: 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.

Abstract: A rotate switch mechanism for actuating time correction displayed by an electronic timepiece comprising a rotatable crown and stem, a toothed wheel rotatably connected to the stem and a switch assembly. The switch assembly contains a switch blade precisely positioned within the periphery of the teeth of the toothed wheel and deflected thereby, with rotation of the crown, to make contact with either of two switch contacts.Circuitry responsive to each switch closure is provided for incrementally effecting time correction, forward and backward, with clockwise and counterclockwise rotation of the crown, respectively.
