Definitions

  • the present invention relates to a watch provided with a device for lighting its dial comprising at least one electric bulb embedded, at least partially, in a light diffuser intended to distribute the light rays which it produces.
  • This watch is characterized by the fact that said diffuser is constituted by a plastic ring placed at the periphery of the dial, at the level of the space located just above the latter.
  • the invention also relates to a watch comprising a source of electrical energy constituted by a battery.
  • This watch is characterized by the fact that said battery is housed in the bottom of the watch case in which it is held by a ring fixing to the notch at said bottom and which bears on the peripheral part of the latter.
  • Fig. 1 is an axial section of part of a wristwatch.
  • Fig. 2 is a plan view of a detail on a smaller scale.
  • Figs. 3 and 4 are two sections of this detail, on a larger scale, along lines III-III and IV-IV, respectively, of FIG. 2.
  • the watch shown comprises a movement 1 provided with its dial, designated by 2, opposite which the hour hands 3, minutes 4 and seconds 5 move.
  • This movement is housed, with interposition of a casing circle 6, in a box comprising a middle-bezel 7, a window 8 engaged in the middle-bezel 7 with the interposition of a gasket 9, and a bottom 10 fixed to the notch to the middle-bezel 7 with the interposition of a gasket 11.
  • the watch shown comprises a device for lighting its dial comprising an electric bulb 12, of elongated cylindrical shape, partially housed in a notch 13 formed in the casing circle and partially housed in a notch 14 which has a ring 15 surrounding the dial 2 and occupying, in height, the space surmounting the latter, made of plastic material such as artificial glass (Plexiglas, Hesalite, Dlichon [registered trademarks]).
  • the bulb 12 is carried by a crown of insulating material 16 fixed to the casing frame 6, under the latter, and which carries the conductive tracks for supplying the bulb leading to the two conductors, designated by 17 and 18 of that -ci, feeding its filament, designated by 19.
  • the annular plate 16 further carries a conductive tab, not shown, extending radially with respect to the watch, coming into contact with the upper face, designated by 20, of a electric battery 21 for supplying the bulb carried by the bottom 10 of the box with which its opposite face, constituting the second pole, is in contact.
  • This stack 21 is held in place on the bottom 10 by a ring 22, made of plastic, having an inner annular part 22 a engaging on the periphery of said stack.
  • This ring 22 hooks to a notch on an annular rib 10 a which the bottom 10 has internally.
  • the ring 15 forming a diffuser, of cross section in the form of a parallelogram, as shown in FIG. 4, has its outer faces - upper and lateral - designated respectively by 23 and 24, which are matt, while its inner face, slightly conical, designated by 25, is mirror-polished (diamond-coated) as is also the face, designated by 26, of the notch 14.
  • the internal face of the bezel 7, in its part surrounding the bulb 12, is also mirror-polished (diamond-coated).
  • the filament 19 occupies the upper part of the bulb 12, either that it is at the same height as the dial, as in the example described and shown, or that it is located above, at the height free space for the passage of needles.
  • the ring 15 also forms a flange given its position between the dial and the crystal.
