  • Patent number: 9256207
    Abstract: The timepiece movement is provided with an analog device for displaying information whose value varies periodically or intermittently, this analog display device including, on the one hand, an indicator provided with a first toothing, and on the other hand, a mechanism for the periodic or intermittent driving of the indicator. The drive mechanism is formed by an irreversible transmission system which ensures a shock resistant function for the indicator. The display device further includes a positioning jumper for the indicator generating a positioning force on the first toothing, which is sufficient to precisely position the indicator in a plurality of discrete display positions, but considerably insufficient to ensure a shock resistant function for the indicator. Thus, the indicator can be driven with a relatively low torque; which therefore requires less energy and makes it possible to provide a drive mechanism with a lower gear reduction for the drive torque transmission ratio.

  • Patent number: 8675453
    Abstract: A backlash-compensating mechanism includes a cam, an actuating member bearing against the cam and a wheel coaxial to the cam and intended to be driven by a gear train of the movement. The cam and the wheel are connected to each other such that one revolution of the wheel includes a sequence of a first phase in which the wheel drives the cam whilst the co-operation between the cam and the actuating member cocks the latter, a second phase in which the actuating member uncocks and causes the cam to effect an instantaneous jump, and a third phase in which the cam is immobilized and the wheel continues to advance until it catches up with the cam to once again drive it during the first phase of the following revolution. This mechanism includes a resilient element acting between the cam and the wheel and applying a return torque to the wheel during the third phase to compensate the backlash in the gear train.

A special metal clip provides a push button contact for electrically setting the watch and also holds the intermediate gear assembly in place.

  • Patent number: 4364671
    Abstract: The invention provides a very thin electronic watch having a casing with a front wall provided with a glass, a rear wall and a side wall connecting the front and rear walls. In the casing there is a spindle substantially perpendicular to the front and rear walls and mounted pivotally with respect to the casing, a toothed transmission wheel secured to the spindle, a "minutes" disc perpendicularly secured to the spindle and provided with a tooth arrangement on its periphery, and an "hours" disc pivotally mounted on the spindle, substantially parallel to the "minutes" disc and provided with a tooth arrangement on its periphery, the "minutes" and "hours" discs being disposed between the glass and the toothed transmission wheel. The casing further has an electric motor, a supply source, a first gear train engaging the rotor of the electric motor and the "minutes" disc and a second gear train engaging the "hours" disc and the transmission wheel.

  • Patent number: 4282592
    Abstract: An electronic analog calendar timepiece includes a mechanism for automatically correcting the date indication at the ends of months having less than 31 days. A second motor activates the month correction-mechanism in short months to advance the date dial by additional indicated days. Such irregular advancements occur in accordance with the condition of switches associated with the 29th, 30th, and 31st day positions of the date dial, and in accordance with data stored in memory to correlate with the displayed month of the year. A conventional driving mechanism associates with conventional time keeping circuitry to advance the hands and the day, date, and month indicators for all days occurring in the month. The month-end correcting mechanism is linked to the conventional driving mechanism by actuation of the second motor.

  • Patent number: 4240249
    Abstract: A day disk cooperates with a storage of mechanical energy via a seven-position Maltese mechanism. A Maltese cross of said mechanism is rigidly coupled to and coaxial with the day disk. A transfer pin of the Maltese cross is set on an intermediate gear of the storage. A driven disk includes a projection for the transfer of a toothed date ring. The locking surfaces of the Maltese cross lock on the driven disk. Provision is made of a free unloaded lever with one arm locking in position the date ring and the other arm of said lever resting against the projections of the Maltese cross, thereby relieving the moment of load of the calendar device on the gear train and improving the reliability of the timepiece.

  • Patent number: 4204395
    Abstract: A calender mechanism comprising a cannon wheel having a gear wheel portion and a cylindrical portion extending axially from the gear wheel portion, a day star wheel mounted for rotation on a cylindrical portion of the cannon wheel, and a positioning plate. The day star wheel has an outer diameter less than that of the gear wheel portion of the cannon wheel, and the positioning plate is positioned to partially overlie the outer peripheral portion of the gear wheel portion for preventing the cannon wheel from traveling axially toward the day star wheel. The portion of the positioning plate overlying the outer peripheral portion of the cannon wheel does not extend between the day star wheel and the gear wheel portion of the cannon wheel.
