  • Patent number: 4488819
    Abstract: The stator (10) of the motor serves as a single plate, not only for the rotor, wheels and spindles for hands, but also for the rocker (72), the pulling crank (70) and the setting pinion of the minutes wheel. The stator is shaped locally to form, on the one hand, a groove which guides the end of the setting stem (64) and, on the other hand, a boss (84) into which is driven a pin (82) serving as a spindle for the setting pinion (80).

  • Patent number: 4483627
    Abstract: A motor module for an analog display watch comprises a single mounting plate which is preferably formed by the stator 2 of the motor. The rotor 32 is mounted in the plate 2 by way of members 26 and 30 which form bearings for the rotor 32. The spindles 18, 22 and 24 for the hands are also mounted on the stator 2. Finally, the spindle 44 for gears 46, 47 and 48 between the rotor and the spindles for the hands passes through the stator 2.

  • Patent number: 4363554
    Abstract: The mechanism has a sliding and rotary stem 2 for controlling two functions of a digital display watch. The stem 2 carries a fixed pinion 4. An intermediate gear 6 is mounted rotatably at the end of a rocking lever 32. Pivotal movement of the lever 32 against the action of a spring 36 is produced by the stem 2. In a first position of the stem 2, the gear 6 is in mesh with a date setting wheel 8 but out of mesh with the pinion 4. In a second position, the gear 6 is engaged by the pinion 4 and remains in mesh with the wheel 8. In a third, fully pulled out position, the gear 6 remains engaged by the pinion 4 and is pulled out of mesh with the wheel 8 and into mesh with a time setting wheel 10.
