Definitions

  • the present invention relates to a watch case comprising a middle part and a plurality of components together defining a housing intended to receive a watch movement and display means, in which the components comprise a crystal and a back and in which the middle part has a recess opening towards the inside of the box, a first bearing surface cooperating with the glass and a second bearing surface cooperating with the bottom.
  • Document CH-A-66541 already describes a hollowed-out caseband enclosing a watch movement.
  • This middle part also has a first bearing surface cooperating with a crystal and a second bearing surface cooperating with a bottom. These first and second bearing surfaces are however not cylindrical but conical since the crystal and the bottom are adjusted to the notch on the middle. Furthermore, the movement is held in place in the middle without the help of studs which would take place in the recess of the middle as will appear in the present invention.
  • the watch case according to the invention in addition to having the characteristics given above in the first paragraph, is characterized in that the first and second bearing surfaces are cylindrical and define openings in which the glass and the bottom are respectively engaged and by the fact that at least three studs integral with the middle part are arranged in the space defined by said recess and are shaped to position axially at least one of said components.
  • the watch case comprises a middle part 1 and a plurality of components comprising a crystal 2 and a base 3.
  • This box is intended to receive a watch movement 17 and means for displaying the time of which only the dial 14 appears here.
  • the middle part 1 has a recess 4 opening towards the inside of the case, a first bearing surface 5 which cooperates with the glass 2 and a second bearing surface 6 which cooperates with the bottom 3.
  • the first and second bearing surface 5 and 6 are cylindrical in this sense that they are directed in the direction of the axis of the box. These bearing surfaces thus define openings in which the glass and the bottom are respectively engaged.
  • each of these studs 7 is shaped to position axially at least one of the components comprising the glass and the bottom.
  • FIG. 2 is an enlargement of the zone II visible in FIG. 1. It recognizes in particular a portion of the middle part 1 and one of the three studs 7 confined inside the recess 4.
  • the stud can be welded into the bottom of the recess, any other means, such as bonding, which can however be envisaged .
  • the watch case presented as an example in FIG. 1 has a round middle and the recess 4 is in the shape of a vault 10 as is clearly seen in FIGS. 2 to 5.
  • This way of doing things is particularly well suited to boxes whose middle is in gold, because it contributes to very significantly decrease the weight of gold and consequently decrease the cost of the watch.
  • the invention could, however, be applied to a form watch with the same advantages indicated above. It will also be noted that the arch-shaped recess contributes to stiffening the middle, more than if it was made without recess.
  • the box is sealed by fittings.
  • the studs 7 were shaped to position axially at least one of the components comprising the glass and the bottom.
  • the stud 7 carries a projection 11 beyond the recess 4 and extending in the direction of movement 17.
  • the axial positioning of the glass 2 is achieved by to an upper batt 12 presented by the projection 11.
  • On this upper batt 12 rests a flange 15 against which the glass 2 rests, the flange serving to ensure a well-defined distance between the dial 14 and the underside of the glass 2 and thus leaving a free space for needles (not shown).
  • the middle part 1 is provided with its pads 7, which pads are preferably arranged at 11 o'clock, at 3 o'clock and at 7 o'clock.
  • the flange 15 is introduced from the top which will come to rest on the upper flaps 12 of the projections 11 of the studs.
  • the annular lining 8 is then introduced and the ice 2 is expelled inside the lining until said ice press the flange, the latter in turn pressing the projection 11.
  • the edge of the ice compresses the gasket 8 against the bearing surface 5 to ensure the watertightness of the watch.
  • the projection 11 of the stud 7 carries a lower battue 13 on which rests a casing circle 16 against which the bottom 3 rests.
  • the casing circle is shaped to hold in place the movement 17, this movement resting in known manner in a housing formed in the casing circle.
  • the movement is fixed to the casing circle by flanges, just as the dial 14 is fixed to the movement by feet of the dial.
  • the movement 17 is introduced with its adjoining circle 16 from the underside of the middle part 1, until the circle 16 comes to rest on the bottom battue 13 of the projection 11.
  • the embodiment shown shows a bottom 3 which is an assembly formed by a ring 20 and a closure plate 21.
  • Ring and plate can be made in one piece or even be attached one on the other by means of glue for example. If the middle part is gold, the plate will also be gold. However, as shown in FIGS. 3 to 5, in order to reduce the weight of gold as much as possible, the plate can be a second lens attached to the ring. The result is a cheap gold box whose precious metal weight can be less than four grams. In this case the goldsmith's punch will be affixed to the middle.
  • the middle 1 carries attachment means 22 of a bracelet held in place by means of pins passing through holes 23.
  • These horns can be made in one piece with the middle or attached afterwards by welding for example.
  • the box provides an opening 18 continued by a hole 19 passing through both the stud 7 and the casing ring 16, which allows the establishment of a setting rod hour, rod which is very conventionally placed in its housing by means of a tube and a seal.
  • the studs 7 are at least three in number to ensure a suitable seat for the components to be assembled. We will preferably choose an opening 10 ° for the stud coinciding with the entry of the rod and 5 ° for the other two.
