  • the hands 14 and 15 are used not only to indicate the current time, but also to display all the other information that the watch can provide. It is therefore necessary for the processing and control unit 3 to know at each moment the position of each of these needles in order to know how much they must be moved to go from the display of the current time to that of one or more other information and vice versa.

  • the unit 3 interrupts the transmission of the 1/60 Hz pulses of the frequency divider of the circuit 2 to its minute hand position counter and transfers the contents of the counter days of the month of this circuit in its minute hand position meter 15.
  • the control circuit of the display 5 responds to this change in the contents of the minute hand position counter 15 by sending the driving motor of this needle motor pulses of much higher frequency than normal so that it turns quickly in one direction or the other to be placed by the shortest path in front of the mark of the graduation 17 of the dial 16 of the watch which corresponds to the day of the month of the current date. If for example this day is 27, the needle 15 comes to the position where it normally indicates 27 minutes.

  • the unit detects that the rod is rotated rapidly, the connection between the frequency divider and the minutes and minutes counters of the minute hand is not interrupted and the unit 3 generates and applies at the inputs of the hour and hour meter positions of the hour hand 14 a number of high frequency pulses which allows this needle to progress or regress by one hour, always in the direction of rotation of the rod of command and whenever it is subject to rapid rotation.
  • the processing and control unit 3 which permanently knows the position of the telescope 23 then blocks the pulses of the frequency divider at the input of its position counter of the minute hand, then after having performed the necessary operations to determine the position in the zodiac of the star selected, it modifies the contents of this counter so that the minute hand moves in a direction or in the other to be placed in the position where it indicates simultaneously the zodiac sign in which this star is and the approximate position of the latter within the sign in question, using respectively the symbols 18 and the graduation in hours and minutes 17 of the dial 16.

  • the disc carrying this planisphere is mechanically coupled to the drive train of the hour hand 14 so as to perform a turn in 24 hours in the counterclockwise direction. Therefore, the planisphere 20 moves along with the hour hand not only when it indicates the current time and when the hours indication is changed by the user, which is quite normal, but also when this needle is used to select a year other than the current year. In fact, this is not very embarrassing. However, this slight inconvenience can be eliminated by driving the disk on which the world map is located by a third motor independent of those driving the hour and minute hands. Another possibility to avoid this would be to display the years not simultaneously by the two hands, but successively by the minute hand.
