  • the four star 71 pivoted on the plate, is thus arranged to make 1/4 turn per day, except two days per week.
  • this star 71 rotated from Monday to Tuesday, it remains in its position on Tuesday and Wednesday, before changing position between Wednesday and Thursday.
  • star 71 rotated from Friday to Saturday it remains in its position on Saturday and Sunday, before changing position between Sunday and Monday.
  • Shutter 20B will display a first position on Tuesday, rotate 180° from Tuesday to Wednesday, to display a second position on Wednesday.
  • shutter 20E will display a first position on Saturday, rotate 180° from Saturday to Sunday, to display a second position on Sunday.
  • the user will see fixed displays on the periphery of roll 20: 20A on Monday, 20C on Thursday, 20D on Friday.
  • This four star 71 carries a secondary wheel 70, which meshes with a roller drive wheel 62, itself secured to the display roller 10.
  • the four-tooth star 71 actually drives, five days a week, this roller drive wheel 62 by 1/5 turn, which corresponds to the five fixed positions of the roller.
  • the main wheel 60 also carries a main shutter drive wheel 63, which itself meshes with a shutter pinion arranged to control a shutter drive pinion centered on the shutter axis D20, or else constituting itself even a 35 flap drive pinion.
  • This main shutter drive wheel 63 performs, like the main wheel, 1/7 turn per day.
  • the flap pinions carry the flaps 20B and 20E on both sides, and mesh with a ratio of 3.5 with the main flap drive wheel 63.
  • the shutter pinion makes 1/2 of a turn, with a change of side of the shutter 20 concerned.
  • THE figures 22 to 26 represent, schematically, a variant for a display of leap years 400.
  • This display of leap years 400 can be done by one or more hands, in particular and not limited to in the example of the figures with a triple needle 401 at 120°, in the extension of the axis 402 of the month roller, facing a complementary leap-year display 403, in particular usually comprising marks such as 1, 2, 3, L, or B, or similar.
  • a star 404 held by a jumper 405, drives this triple needle 401, and is itself driven by an eccentric lever 406 secured to a flap 407.
  • the rotation of the star 404 is done by an eccentric lever 406 integral with component 407 for the months of March/September.
  • this flap 407 pivots via the toothed sector 408, the latter pushes the star 404 by one notch, as visible on the figures 24 and 25 .
  • the roller makes one revolution in six months, in July the lever does not trigger the rotation of the star.
  • FIG. 27 illustrates another variant of maintaining the flaps 407 without a jumper, and with drive by partial teeth, with guidance by an external circumference 420 in contact with the flap 407 itself.
  • the shutter 407 is guided into position by two teeth 410, 411, of its drive pinion 409. This can have one or more teeth removed, at the level of a recess 412, to facilitate the function.
  • the support is advantageously done on a partial exterior or interior guide circumference, by two teeth delimiting a circumference of rotation crossing the guide circumference. This crossing limits the rotation of the rollers on their axes.
  • the guide circumference is interrupted on a portion 421 allowing rotation. This rotation is controlled by a tooth segment 408 provided for this purpose. This can, as in the figure, form part of the guide circumference 420.
  • the shutter in a shutter variant without jumper, the shutter can be guided directly by an external circumference in contact with the shutter itself. In this way, the guide circumference is interrupted to allow the shutter to pass.
  • the drive pinion can then be found in the configuration of the variant of the figures 7 to 11 , or even in that of figures 17 and 18 .
  • the different variants of the invention make it possible to produce roller displays of all kinds of indications in the reduced volume of a normal-sized watch, in particular with a total thickness of around 10 mm outside the crystals. , or ice and bottom.
  • the shutters are not in contact with no part of the watch, and are not subject to any shock or friction in the course of their normal operation.
