Definitions

  • the object of the present invention is a watch of any type, but preferably a self-winding wristlet watch.
  • Fig. l is a section of that part of the movement necessary for the understanding of the invention.
  • Fig. 2 is a view of the scale and indicator and of the means by which they are driven;
  • Fig. 3 is a view of the watch dial drawn to a smaller scale.
  • the barrel being shown at 1 in Fig. l and its arbor at 2, the first one turns as the barrel spring unwinds and the second one on the other hand when the said spring is being wound.
  • Each of these two members drives a toothed wheel, that is to say, the pinion 3 for the barrel and the pinion 4 for the barrel arbor.
  • these two wheels drive an indicator and a scale which appear on the watch dial.
  • the pinion 3 drives the toothed wheel 5 which makes the disc 6 revolve.
  • the pinion 4 drives the toothed crown 7, which surrounds the disc 6, concentrically and revolves about the said disc. The drive is effected by means of the gearing 8 of the said crown.
  • the reduction ratio between the pinions 3 and 4 and the gearings 6 and 8 respectively is identical. This is achieved in the example illustrated by utilizing both similar pinions and similar gearings. This ratio is such that, to the total number of revolutions corresponding to the winding up of the barrel spring or to its unwinding, there corresponds slightly less than one revolution of the rotating disc 6 and crown 7.
  • the disc 6 carries an index or pointer 9 which cooperates with a circular scale having graduations reading from five to forty.
  • the portion of the scale existing between the graduation labeled 5 and the graduation labeled 40 and designated at 7 represents an area of main spring run-down, while the graduation labeled 40 represents a condition of maximum main spring wind.
  • the scale of the crown 7 and the index 9 of the disc 6 thus form a clear differential, of which the relative position of the two members opposite one another will be a constant indication of the running reserve stored by the barrel spring.
  • this reserve is twenty eight hours and in the example shown in Fig. 2 it is the maximum, that is to say, forty hours.
  • the gearwheel 5 drives the disc 6 by means of a Breguet gearing 11, the meshing of which is ensured by a foil 12, by providing said disc with a pin 13 and by adding to the crown 7 a collar 14 bearing a stop 15.
  • the whole is arranged angularly in such a way that at the moment when the index 9 indicates the maximum running reserve, the stop pin 15 engages one side 16 of the pin 13, this side being in alignment radially with the maximum reading of the scale on the crown 7 and limits further relative movement between the crown 7 and disc 6. If further winding is attempted, thus causing rotation of the crown 7, the stop 15 will push the pin 13 before it and the disc 6 will carry out the same angular movements as the crown wheel, the index remaining opposite the maximum on the said crown wheels scale. There is no longer any relative movement, the differential eifect is momentarily eliminated.
  • the disc 6 with the single index 9 thereon could also consist of a single pointer.
  • a barrel a winding spring disposed within said barrel and operatively connected thereto and movable between unwound and fully wound positions, a winding arbor concentric with the barrel and operatively connected to the spring for winding the latter, and means for rendering a visual indication of the extent to which the spring is wound
  • said means comprising an indicating ring having a circular scale thereon extending through substantially 360 in circumferential extent and provided with a comparatively wide run-down indication and an adjacent sharp maximum wind indication, a disc disposed within said ring and having a pointer thereon designed for cooperation with the scale, said ring and disc being mounted for relative rotation about a common axis, a first gear train operatively connecting the arbor and ring in driving relationship, a second gear train operatively connecting the disc and barrel in driving relationship, a one-way slip clutch interposed in one of said gear trains and permitting said disc to continue to rotate after the spring has been fully wound on said arbor, means on said ring providing an in
