Definitions

  • the present invention relates to a watch case of the type in which the crystal is fixed in a bezel or flange by means of a seal, this bezel or this flange being attached to the middle of the box by screw fixing means.
  • this box As for the bottom of this box, it is press fitted to the middle by means of a notching system.
  • the present invention aims to provide a watch case using an arrangement similar to that described in the aforementioned patent, but allowing advantageously to attach to the middle by screwing, not only the flange, but also the bottom.
  • a watch case comprising a middle part, a crystal mounted in a flange which is attached to said middle part by a plurality of first screw fixing means, and a bottom also attached to said middle part, said case being characterized by that said base is attached to said middle by a plurality of second screw fixing means, each pair of first fixing means and second fixing means having a common axis, and in that each of said pairs of first and second fixing means comprise a single stepped passage centered on said common axis.
  • the watch case according to the first embodiment of the invention comprises a middle part 1 composed of an outer ring of hubcap 2 and an inner ring of reinforcement 3.
  • the hubcap ring 2 comprises a peripheral part 2a and a central veil 2b which preferably serves as the dial of the watch, as well as an interior cavity 2c in which the reinforcement ring 3 is received.
  • hubcap 2 can be made of any suitable material, but advantageously it can be made of wood or a mineral material such as stone, for example.
  • the reinforcing ring 3 is also formed of a peripheral part 3a and of a central veil 3b and it fits in the cavity 2c of the hubcap ring 2 where it can be held in place by an adhesive joint 4 It in turn comprises an internal cavity 3c intended for house movement 5 of the watch. This is held in place by a casing circle 6, as is conventional.
  • the latter On the side of the face of the web 2b opposite the cavity 2c of the ring 2, the latter has an upper cavity 7 in which a flange 8 is fitted.
  • the latter has a shoulder 9 against which a glass 10 which is held in the flange by means of a seal 11. It will be noted that the upper surface 12 of the ring 2 is flush with the upper surface 13 of the flange 9 from which the glass 10 is slightly protruding upwards.
  • the flange 9 On its underside, the flange 9 has a peripheral groove 14 intended to accommodate a seal 15 which is compressed against the web 2b during assembly of the box.
  • the reinforcing ring 3 has a groove 16 for housing a seal 17 which is compressed by a screwed bottom 18 when the box is mounted.
  • the bottom 18 has fixing lugs 19 to allow a strap 20 to be attached to the box.
  • the box comprises several assembly assemblies with screws 21 making it possible to hold together all the constituent parts of the box which have just been described.
  • the passage 22 narrows from the bottom 18 to the flange 8, with d1> d2> d4.
  • the diameter d3 of the hole 27 may be slightly larger than the diameter d2.
  • Each assembly assembly further comprises a first screw 29 of diameter dl intended to fix the bottom 18 on the ring 16, as well as a second screw 30 of diameter d4 for fixing the flange 8 on the rings 2 and 3.
  • the head of the screw 30 bears against the shoulder 26 of the connection part 25c.
  • Figure 3 shows another embodiment in which, relative to the embodiment of Figures 1 and 2, the trim ring 1 and the reinforcement ring 3 have been replaced by a single middle 31 in which is pierced the part corresponding to the single stepped passage 22.
  • a dial 32 is mounted on the middle part 31 and taken between the flange 8 and a radial shoulder 33 of the middle part 31.
  • the middle part 31 has only one single hole 34 of diameter d3 which can be drilled at the same time as the hole 25, the part 25b of diameter d2 present in the embodiment of FIGS. 1 and 2, not being necessary in that of FIG. 3.
