Definitions

  • timepiece equation movements These watches or clocks with time equation have a pair of hour and minute hands which indicate, as in the generality of the watches, the average or civil time. These watches also indicate the time difference between civil time and real time, thanks to a time equation cam.
  • the object of the invention is to provide a timepiece movement with a perpetual calendar simultaneously indicating the difference between civil time and real time. It is therefore a movement with a perpetual calendar according to the Gregorian calendar and a perpetual time equation.
  • Figure 1 is a schematic view of the movement.
  • Figure 2 is a view of the dial.
  • the movement shown in Figure 1 has three mechanisms.
  • the first mechanism comprises, at the center of the movement, an hour wheel 1, meshing a 24-hour wheel 2 carrying a drive finger 3 intended to lift a multiple rocker 4, perpetually, once every 24 hours.
  • a beak of the rocker rotates a tooth a star 5 to 7 teeth, indicative of the days of the week and simultaneously rotates the date wheel 6 to 31 teeth.
  • the date wheel 6 is angularly integral with a spiral 7.
  • the multiple lever 4 comprises a catch pawl 8, cooperating with the spiral 7 and a lever arm 9 cooperating with the steps of a cam 10 divided into 48 steps the depths of which vary according to the length of the months they represent. This cam 10 is angularly secured to a wheel 11 of 48 teeth.
  • the catching ratchet 8 slides around the circumference of the spiral 7 without producing an effect until the lever arm 9 is pressed on the step of the 16 months of 30 days, the 3 months of 28 days or on February 29 leap year. At this moment the tip of the pawl 8 engages in the notch of the spiral 7. The pawl 8 then drives the additional teeth and passes to the first day of the following month. An end-of-month finger 12 then drives the return wheel 13 which, at its turn will advance the 48-month wheel 11 by one tooth together with the 48-month cam 10 which itself will cause an intermediate return of the 12-month indicator 14 and, consequently, the 12-month wheel 15. Thanks with this mechanism, the date wheel 6 comprising 31 teeth rotates 360 ° whatever the number of days included in the month.
  • the second mechanism comprises a time equation cam 16 with which a feeler 17 cooperates which is integral with a toothed sector which actuates a pinion 18 carrying a needle 19 indicating the momentary difference between the civil time and the real time.
  • the cam 16 is rotated by the clock mechanism.
  • the third mechanism comprises a succession of pinions and wheels, connecting the date wheel 6 to the time equation cam 16.
  • FIG. 2 An example of the dial of an automatic wristwatch provided with the movement represented by FIG. 1 is represented by FIG. 2.
  • the middle of the display window 24 for the day of the week, the center 25 of rotation of the hand 26 indicating the months, which coincides with the center of rotation 25 of the time hands 27 and 28 , and the center of rotation 29 of a hand 30 indicating the date, are arranged on the median straight line of the dial.
  • a hand 32 indicates the current year with respect to the leap year.
  • two graduated sectors 33 and 34 are provided located laterally and symmetrically on either side of the center line of the dial in its upper part.
  • Sector 33 includes an arc of 62 ° whose center 35 is provided with a hand 36 indicating the positive or negative variation of the real time in minutes compared to the civil time indicated by the hour hands 27 and minute 28 the center of rotation of which is located at 25.
  • the sector 34 comprises an arc of a circle of 60 °, the center 37 of which is provided with a needle 38 indicating the remaining running autonomy of the automatic movement.
  • the position of a trade mark completing the symmetry of the dial has been indicated at 39.
  • the timepiece movement of the invention is advantageous since it allows, after an indefinite stop time of the movement, to automatically return the equation cam to the exact position and without possible error, by simply resetting the date phase, of the year, month and hour.
