Definitions

  • the present invention relates to a waterproof watch case, according to the preamble of claim 1.
  • the middle part of the bezel has the function of positioning, in the case, the casing circle which, in turn, positions and immobilizes the movement in the box. It has, in addition, the function of receiving the fixing screws of the base and, finally, the exterior surfaces of the middle part of the bezel constitute an important element of the aesthetic appearance of the case. Given these functions and the required stability, these glasses must necessarily be massive. Therefore, made of precious metal, they are necessarily expensive.
  • the watch case described in EP-A-0 150 746 has a middle, designated by outer ring in this document which serves as a protective and decorative element. It is formed of a solid piece of hard material and concentrically receives the casing circle which is designated by inner ring and which also receives the fixing screws of the bottom and of the front plate formed of the glass and, in certain examples , ice and a telescope.
  • the watch case according to EP-A-0 150 746 should be provided with an outer ring (middle) and, in some examples, in addition to a bezel, made entirely of gold so that they can be designated as a gold box.
  • the problem which is the basis of the present invention is to produce a watch case of the aforementioned type very flat, very light and waterproof by a reliable system and which, in particular, allows, compared with the boxes of the prior art , a significant saving of precious metal when it is made as a gold or platinum box while fully respecting the precious metal regulations concerning watch cases.
  • the envelope has practically no forces to absorb. It can therefore be designed with a minimum of material resulting in a significant saving of precious metal of up to 60 to 70% compared to conventional monocoque constructions known until now while retaining all the technical advantages of a screw-down case, including easy access, even to a non-professional, for changing the battery when the box receives a quartz movement.
  • the embodiment according to claim 6 makes it possible to further reduce the thickness of the watch case compared to known constructions with seals stored between the base and the middle part.
  • the waterproof watch case according to each of the two exemplary embodiments represented in the drawing comprises a middle part of the bezel designated as a whole by the reference 1.
  • This middle part of the bezel 1 consists of two concentric annular parts 2 and 3 fitted one into the the other with friction engagement.
  • the inner part of these two parts is a rigid ring 2 which can be made of common metal or plastic.
  • the outer part of the two parts making up the middle part of the bezel 1 is made of precious metal, for example gold or platinum, and forms an envelope 3 covering the periphery of the rigid ring 2.
  • the casing 3 of precious metal is formed on its inner face with a notch 4 on which the underside of a shoulder 5 of the rigid ring 2 rests so as to prevent the latter from sliding axially downward in the casing 3.
  • the lower faces 6 of the rigid ring 2 and 7 of the casing 3 which are planar, are in the same plane and serve to support the bottom 8 of the watch case as will be seen later.
  • a second notch 9 is formed at the upper end of the casing 3 to receive the glass 10 which is stuck thereon so as to seal the upper opening of the middle part-bezel 1 while increasing the rigidity of the glass / envelope assembly.
  • the rigid ring 2 is inserted in the casing 3 before the fixing of the glass 10, thus giving the casing 3 the rigidity necessary to allow the gluing of the glass 10. Due to the presence of the notch 4 and from shoulder 5, insertion of the rigid ring 2 can only be done from the upper opening of the envelope 3.
  • the upper surface 11 of the rigid ring 2, which is visible through the glass 10, can be decorated, for example by a metal deposit where it can be hidden.
  • this part of the rigid ring 2 visible through the glass 10 is hidden by a decorative ring 12 or designed as an hour wheel and placed in an appropriate housing of the middle part.
  • this rigid ring, designated here by 12a is glued to the underside of the glass 10 or come in one piece with it. It can be made of sapphire, ceramic or precious metal.
  • the movement 13 fitted with the dial 14 can be placed in the box through the lower opening of the middle part-bezel 1.
  • the movement 13, 14 is positioned in the box in a known manner using a casing ring 15.
  • two seals are provided in the form of rings 16a and 16b, of different diameter.
  • One of these rings is placed so as to protrude slightly from the lower face 6.7 of the middle part, in a housing formed between the peripheral surface of the rigid ring 2 and a bias 17 of the inner face of the casing 3.
  • the second seal, designated by 16b is placed around a rib 18 at the bottom 8.
  • the seals 16a, 16b put in place, the box can be closed by applying the bottom 8, the diameter of which is such that it exceeds the diameter of the interior opening of the envelope 3.
  • the bottom 8 is fixed to the middle part of the bezel 1 using fixing screws 19, screwed into threads 20 worked in the rigid ring 2. Tightening these fixing screws 19 causes the circle d to be blocked.
  • casing 15 by the action of a bottom surface against a part, here a rib 22, of the casing circle 15 which applies the dial 10 against a support 21 of the rigid ring 2.
  • the casing 3 can be further lightened by providing in its internal surface, recesses 24 which makes it possible to save additional weight and precious metal without affecting the external appearance of the watch case.
  • Another way of saving precious metal while respecting the prescriptions for precious metals would be to replace a bottom 8 made entirely of precious metal by a bottom which, as shown in the example in FIG. 1, is formed from two pieces, namely an outer ring 25 of precious metal in the opening of which is bonded a plate 26 of glass or other non-metallic material.
