Winding And Setting Patents (Class 368/31)
  • Patent number: 9389589
    Abstract: In the control method for an analog display device fitted to a timepiece movement, the motor is used both for driving a first indicator of a time parameter and a second periodically driven indicator. To this end, the motor is controlled such that, when the first indicator is in an operating mode and the second indicator is arranged to remain substantially immobile, said first indicator is driven in rotation by the motor alternately. The first indicator is driven in a forward direction, to display the time parameter, during a first period in which a periodic actuation wheel set is simultaneously driven in positions of its area of non-actuation, and in a backward direction, in accelerated mode, during a second period following the first period, before the periodic actuation wheel set is driven in a position of its area of actuation.

  • Patent number: 7408844
    Abstract: A calendar watch is arranged to allow time-setting to be carried out without this operation altering the state of the calendar mechanism at the passage to midnight. This mechanism, which is of the instantaneous date type, includes a large lever (2) loaded by a spring and wound by a spiral shaped cam (11) and a click (20) released at midnight by a flexible finger (12) of a 24-hour wheel (10). The mechanism prevents any transmission of movement from the 24 hour wheel to the date wheel set, when they are set in the active position by the winding stem (33) pulled out into the time-setting position of the watch. A pivoting isolator (30), which, in its active position, abuts against the click (20) prevents the click from releasing the lever (2).

  • Patent number: 6128252
    Abstract: When an analog indicator is enabled, the position of the time indicator is detected by an indicator position detection circuit. When the indicator arrives at a predetermined position, typically 24:00, a CPU advances calendar data to a correct date and stores the calculation result in a calendar counter. The CPU outputs a drive instruction signal to a date-indicating wheel drive pulse generating circuit to drive a date-indicating wheel to the correct date. The date-indicating wheel drive pulse generating circuit then drives the date-indicating wheel to a renewed position. At this time, a time counter is cleared to 0:00 and is synchronized with the position of the analog indicator. When driving of the analog indicator is disabled, such as by the pulling out of a crown switch, and the time counted by the time counter arrives at a predetermined time, typically 24:00, the CPU advances the present calendar data to the correct date and stores the calculation result in the calendar counter.

  • Patent number: 5093814
    Abstract: A process for programming the perpetual calendar of a watch with analog time display is effected using elements incorporated in the watch. The hand of the watch and the position of the hand is used to indicate the steps of the programming. The operation of the stem places the watch in the program mode. If it is required to program three parameters, namely, the number of the year in a four year cycle, the number of the month of the year and the day of the month; and if the watch has a hand setting stem with three positions, each parameter to be programmed is allocated to a position of the stem and the parameters to be programmed are read from the second hand by allocating to the latter real steps corresponding to stopping positions and non allowable steps corresponding to non stopping positions.

  • Patent number: 4775963
    Abstract: 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.

  • Patent number: 4261046
    Abstract: In an analog timepiece having calendar displays for day and date, a transducer operating independently of the hand driving transducer, feeds, that is, updates the calendar wheels automatically on a daily basis. Synchronization of the daily day and date changes is provided by a twenty-four hour wheel cooperating with the time-keeping mechanism. For setting the calendar displays, turning the stem in one direction polarizes a magnet and advances the day wheel, while turning the stem in the other direction reverses the polarity of the magnet and advances the date dial until desired settings are accomplished. The date advancing transducer can be automatically actuated for end of the month date adjustments.
