Quartz watch with analogical time display, comprising a manually controlled time altering device

In an electronic watch with a manually operable displayed time altering device, a quartz oscillator providing a time signal, a frequency divider connected to said oscillator and providing a first string of pulses having a predetermined frequency and a predetermined sign, a bi-directional stepping motor normally rotatively driven by said first string of pulses in a sense corresponding to the sign of said first string of pulses, a gear train driven by said motor and a time display device comprising hands,

• the improvement wherein said hands are permanently coupled together through said gear train and said displayed time altering device comprises:
• a control member displaceable from an inactive rest position to an active position, said control member being mechanically coupled to drive said gear train and associated hands when in said active position,
• switch means operatively associated with said control member and placed in a first operative condition when said control member is in said inactive position and in a second operative condition when said control member is in said active position, said switch means, when in said first operative condition, allowing said first string of pulses to be supplied to said motor and, when in said second operative condition, interrupting the supply of said first string of pulses to said motor;
• and,
• a recording means comprising
• a detector coupled to said gear train and providing a second string of pulses when said gear train is driven by said control member, the number and sign of said second string of pulses corresponding to the amount and sense of displacement of said hands, said detector being activated by said switch means being in said second operative condition, and
• counter means receiving said first string and pulses when said switch means is in said second operative position and having a predetermined counting capacity corresponding to the smallest time alteration to be effected, said counter means being activated by said switch means being in said second operative position to count said second string of pulses in accordance with the sign thereof and to algebraically add said first string of pulses from said divider to said counted second string of pulses, said counter means being responsive to said switch means moving from its second operative condition to its first operative condition to quickly feed a number of pulses to said motor corresponding to the sign and number of pulses resulting from said algebraic addition to thereby move said gear train and associated hands to a corrected time position.
