Patent ID: RE41686

Claim:
In an electronic watch having an electrical power generator means for generating electrical power, an electrical power storage means for storing electrical power generated by said electrical power generating means, an oscillator circuit for producing an output signal, a time-signal generating means for generating a time-signal output in response to the output signal from said oscillator circuit, and a time display which displays time information , responsive to said time-signal output from said time-signal generating means, with a plurality of time indicating hands, an improvement further comprising: a control section for switching a display of a condition about said electronic watch on said time display; a voltage detection means for detecting the voltage of said electrical power storage means and for producing an output detection signal; and a control section management means for controlling the operation of said control section in response to the detection signal of the voltage detection means, wherein said control section causes at least one time hand of the plurality of time indicating hands in said time display to move to and to stop at a pre-established position without performing any mechanical operation when the value of said detected voltage drops below a predetermined reference value, during said time display displaying time information, so as to indicate such voltage drop ; wherein when said electronic watch assumes a first status, said control section causes at least one time hand of the plurality of time indicating hands in said time display to move and to stop at a first pre - established stopping position which indicates a charge warning state of said electrical power generator means, and when said electronic watch assumes a second status, said control section causes said at least one time hand to move and to stop at a second pre - established stopping position which indicates that the timekeeping function of said electronic watch is stopped .
