ABSTRACT:
The apparatus comprises commutating means 10 operated by the rotation in one direction or the other of the watch spindle 1, which rotation produces trains of commutation pulses that are phase-displaced with respect to each other. The watch circuit produces from the trains of commutation pulses a signal indicating the direction of rotation of the spindle and produces selection or correction pulses. The commutating means comprise two cams 2, 3 mechanically coupled to the rotatable spindle 1, angularly displaced one with respect to the other and arranged to actuate two resiliently flexible strips 4, 5 which are fixed at one of their free ends and the other free ends of which are alternately brought into contact with and removed from respective fixed contacts 7, 8. The watch circuit can include means for rendering ineffective a predetermined number of selection pulses at the beginning of the rotation of the spindle in one direction or the other.
