Definitions

  • the subject of the present invention is an electronic watch with a needle display comprising a cog driving the hands and a stepping motor driving the cog, and in which the cog comprises a counting wheel provided with a tracking device which cooperates with a movable detector member linked to a detection circuit and to a counter, said detector member being capable of causing the emission of signals in the detection circuit when the counting wheel performs a rotational movement
  • a notch zeule 2 at the periphery of the disc 1.
  • a single detector blade 5 it is possible to provide a counting mobile which is provided with several regularly distributed notches along its periphery, which makes it possible to determine the angle which the mobile 1 has turned. With details which can be much greater than the 360 ° represented by the presence of a single notch.
  • the use of a single detector plate makes it possible to carry out much finer angular detections than when using several contacts or several photosensitive diodes arranged along the periphery of the disc.
