  • Patent number: 9703262
    Abstract: In an annual or perpetual calendar mechanism, a day-of-the-month wheel includes a notch. At each actuation of a lever, a first pawl finger effects an actuation of one step, on one of the teeth of the day-of-the-month wheel. Upon actuation of the lever at the end of a month of fewer than 31 days, a second pawl finger effects, in the notch, an actuation of the day-of-the-month wheel by a whole number of steps. The notch is positioned between two consecutive teeth among the teeth of the day-of-the-month wheel. The day-of-the-month wheel has a peripheral edge which forms the profiles of its teeth as well as the notch.

    Abstract: In an annual or perpetual calendar mechanism, a lever bears a maneuvering device of a day-of-the-month wheel. A month wheel defines course beginning stops, each associated with a month and operational for controlling a course beginning position of the lever when the month wheel is in the angular position associated with this month. These course beginning stops are bottoms of slots alternating with the teeth of the month wheel. The month wheel has a peripheral edge which forms the profile of its teeth as well as the course beginning stops.

    Abstract: A high-speed rotating wheel rotates at high speed by a third stepper motor which meshes with a portion of teeth of a ratchet wheel. A transmission projection of the ratchet wheel moves within an elongated hole of a transmission wheel which rotates with the movement of the hour hand. The ratchet wheel rotates at high speed, and a display wheel rotates at high speed by the high speed rotation of the ratchet wheel via a feed wheel. When normally moving the hour hand, the ratchet wheel rotates with the transmitting wheel and the portion of teeth of the ratchet wheel is made to approach the high-speed rotating wheel. When the display of the display wheel changes, the high-speed rotating wheel meshes with the portion of teeth of the ratchet wheel and rotates the ratchet wheel at high-speed. Accordingly, the date display of the display wheel can be quickly changed.

  • Publication number: 20140146645
    Abstract: The mechanism (1) drives the hands (8, 9) of an electromechanical watch. It includes an electric motor (2), a set of gear wheels (3, 4, 5, 6, 7) connected to the electric motor to move the hands forward or backward on each actuation of the electric motor, and a locking device (20). The locking device (20) includes a piezoelectric actuator (21) for locking, in a rest mode, directly or via a bolt (22), one wheel of the set between each actuation of the electric motor. The piezoelectric actuator (21) releases the wheel of the set of gear wheels (3, 4, 5, 6, 7), when it is actuated by an electrical signal at the moment of each actuation of the electric motor (2) to move the hands forward or backward.

  • Publication number: 20140104992
    Abstract: A watch of the present invention includes a calendar date finder in the form of two interacting disks rotatable relative to the other thereby providing calendar date information. A first disk has a circular periphery with a numeric indicia printed thereon. The numeric indicia is further defined by segments representing months of the year with each segment presenting sequential numbers representing the thirty-one or thirty days of the calendar month. A second disk has week day indicia printed thereon uniformly spaced along the periphery thereof, in a sequential pattern and a marker printed thereon. The position of the marker next to any given day indicia on the first disc as both disks are rotatable next to one another will indicate a day of a future event indicated on the first disk within the segment as the user will identify number of weeks counted from the marker.

  • 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.

  • Patent number: 8526272
    Abstract: A day clock has day, hour, and minute hands revolving continuously around a common center. It has a time adjustment knob and a day adjustment knob. When the day adjustment knob is pulled out, a set of gears are disengaged, allowing the day hand to be adjusted with that knob without affecting the other hands. Then, when the set of gears are reengaged, the time adjustment knob can be utilized to set the time of day. In order to set the day and time accurately, the user may first set the time to midnight with the time adjustment knob, pull out the day adjustment knob, set the day to a clock face line between days with that knob, push that knob back in, and then set the time to the correct time with the time adjustment knob.
