Definitions
- a fluid-tight watch case comprises a back casing and a bezel including a glass connected by screws, a fluidtight packing interposed between the back casing, bezel and glass, and a frame for supporting a watch movement.
- Said screws each have a head countersunk in the bezel and are screwed into a rod having a tapped bore, each rod having means for effecting rotation thereof.
- Each screw and rod passes through and is embedded in the fluid-tight packing and ensures fluidtightness between the glass and the bezel, between the back casing and the bezel and between the back casing and the movement frame.
- This invention relates to watch cases.
- This fluid-tight watch case has a back casing and a bezel including a glass joined together by screws, a fluid-tight packing interposed between this back casing, bezel and glass and a frame intended to support the movement of the watch.
- the main object of the watch case according to the invention is to ensure complete fluidtightness of all the parts of the watch case, the other objects being a new aesthetic shape and particularly easy assembly.
- This fluid-tight watch case is characterised by the fact that the screws each have a head countersunk in the bezel and that each is screwed into a rod with a tapped bore, this rod comprising means for effecting its rotation and each screw and rod being embedded in the fluid-tight packing which ensures fluid-tightness between the glass and the bezel between the back casing and the bezel and between the back casing and the movement frame.
- FIG. 1 is a plan view of a watch case
- FIG. 2 is a cross-section taken along the line lIll of F IG. 1;
- FIG. 3 is a cross-section taken along line llllll of FIG. 1.
- the watch-case shown in the drawing has a back casing 1 provided with lugs or loops 2 for the attachment of a strap or bracelet.
- This back casing 1 includes an annular bearing surface 3 for a fluid-tight packing 4.
- This packing 4 when in a non-compressed state has a generally square-shaped cross-section with a deformable projection at each corner, as indicated in broken lines in FIGS. 2 and 3.
- This watch case also has a bezel 5 which mounts a glass 6, made preferably of a hard inorganic material such as hardened glass or corundum. This mounting is ensured by a ledge 7 in the glass 6 co-operating with the edge ofthe bezel 5.
- Rods 9 with tapped bores 10 threadably receiving screws 8 connect the bezel 5 to the back casing l and ensure compression of the fluid-tight packing 4.
- the screws 8 and 9 pass through and are embedded in the packing 4.
- the screws 8 have a non-circular head 11, embedded in the bezel 5; they are, for example, hexagonal so as not to rotate when the rods 9 are screwed thereon.
- they are provided with a slot 9a to receive a screwdriver.
- any other known means my be provided in the head of the rod 9 to permit its rotation (lmbus or Philips slots for example).
- the fluid-tight packing 4 ensures that the case is completely fluid-tight, since it acts between the bezel 5 and the casing back 1 at A, between the bezel 5 and the glass 6 at B and between the casing back 1 and a casing ring 12 for a watch movement 13 at C.
- the watch case according to the invention can be easily constructed, is effective even at high pressures and has an aesthetic appearance.
- a fluid-tight watch case comprising a back casing and a bezel including a glass connected by screws, a fluid-tight packing interposed between the back casing, bezel and glass, and a frame for supporting a watch movement, said screws each having a head countersunk in the bezel and being screwed into a rod having a tapped bore, each rod having means for effecting rotation thereof, and each screw and rod passing through and being embedded in the fluid-tight packing, said fluid-tight packing forming means for ensuring fluidtightness between the glass-and the bezel, between the back casing and the bezel and between the back casing and the movement frame.
