    摘要: The circuit comprises a counter (13), a generator (11) that produces a reference signal (Sf) made up of pulses, and a two-input AND gate (10). One input of the AND gate is connected to the generator while the other input receives a signal (Sx) produced by a bouncing contact (X) as it switches from an open position to a closed position and vice versa. The output of the AND gate is connected to the clock input (C113) of the counter, which further has a reset input (R13) connected to the output of an inverter (14) whose input receives the signal produced by the contact.Opening of the contact causes the reference signal to be blocked by the AND gate and the counter to be reset. Closure of the contact causes the AND gate to open to the reference signal whose pulses then increment the counter and the latter, upon its contents reaching a predetermined value, issues an output signal (S13) in the form of a pulse.

    摘要: The watch has a first motor for driving a time display, a second motor for driving a numerical indicator of the day of the month, a perpetual-calendar circuit, a first transmission circuit, a non-volatile memory, a second transmission circuit, an initialization circuit and a detection circuit for generating a signal when the cell that energizes the circuit is being replaced. The calendar circuit includes day, month, and year counters. The contents of the month and year counters are transferred to the non-volatile memory by the first transmission circuit in response to periodic signals. The date on which the watch stops at the end of the cell's life is memorized by the day of the month indicating means and the non-volatile memory. Upon insertion of a new cell and in response to the detection signal, the contents of the non-volatile memory are transferred into the month and year counters by the second transmission circuit. The day counter is put into agreement with the day of the month indicator upon date setting the watch with the aid of the initialization circuit.

    摘要: This invention is concerned with an analogue calendar watch able to display the hour, the day of the month perpetually, and whenever required, the number of the month via the day of the month display. The watch includes a first motor driving the time display in response to a time base signal, a perpetual calendar circuit including a day counter, a month counter and a year counter and receiving a daily signal supplied by a contact, a control circuit connected to the calendar circuit, and a second motor driving the day of the month display in response to a signal from the control circuit. The display of the number of the month is achieved with a reading circuit that receives from the calendar circuit signals representative of the contents of the day and month counters. The reading circuit issues to the second motor, in response to a month call signal, a control signal to change the day of the month being displayed to the number of the month, and a further control signal to move the day of the month display back to its original position.

    摘要: A watch comprises a first motor (2) for driving a time display (4), a second motor (23) for driving means (20) for numerically indicating the day of the month, a perpetual-calendar circuit (30), a first transmission circuit (40), a non-volatile memory (41), a second transmission circuit (42), and a detection circuit (43) for generating a signal (S43) when an energy supply cell is being inserted to energize the circuits. The calendar circuit includes counters (31, 32, 33) generating a calendar signal (S30) representative of the date. This signal is periodically transferred to the non-volatile memory by the first transmission circuit in response to periodic signals (Sx, Sm, Sa). The date at which the watch stops at the end of the cell's life remains memorized in the non-volatile memory and in the day of the month indicating means. When a new cell is inserted, the signal representative of the date at which the watch stopped is transferred from the non-volatile memory to the calendar circuit by the second transmission circuit in response to the signal (S43) generated by the detection circuit.
