Definitions

  • the present invention relates to a waterproof watch case, in particular for a diving watch.
  • the watch case which includes a watch movement or a time-based watch module, must be closed in a well-sealed manner.
  • the watch case includes a back fixed in a sealed manner to a first side of a caseband and a crystal fixed to a second opposite side of the caseband. Sealing gaskets are provided at the assembly of the back, the caseband and the watch crystal.
  • a control or adjustment member for functions of the watch is also mounted in a sealed manner through the caseband of the case in the rest position.
  • Watch cases are generally not configured or assembled to withstand high water pressures for example when diving since the pressure inside the watch case is close to atmospheric pressure. Simple traditional watch gaskets are not sufficient to ensure a good watertightness of the case when diving to very great depths underwater.
  • the patent application can be cited CH 690 870 A5 which describes a watertight watch case.
  • the watch case consists of a crystal fixed on an upper side to a caseband-bezel and a back fixed to the caseband by screwing it to an internal thread of the caseband.
  • the crystal is fixed to the caseband by an annular sealing gasket of toric shape and resting on an edge of the caseband.
  • a sealing gasket is also provided between an outer edge of the case back and a lower surface of the caseband. Since the thread can be damaged under high water pressure, a resistant metal cup is also provided, resting against an inner surface of the case back and against an inner edge of the caseband.
  • this does not guarantee good sealing of the case when diving to very great depths underwater, which is a disadvantage.
  • the patent CH 372 606 describes a watertight watch case, which has a central part or caseband surrounding a back and closed by a crystal. A threaded ring is supported against an inclined outer surface of the backband to retain it, and is screwed to a fixing part connected to the caseband. With such an arrangement presented, this does not allow to guarantee a good watertightness of the case during a dive to very great depths underwater, which constitutes a disadvantage.
  • the patent CH 378 792 describes a waterproof watch case.
  • the crystal is a disk of transparent mineral material (glass, crystal).
  • a soft or malleable metal trim such as gold, platinum, silver, copper, tin, is driven into the periphery of the crystal against an upper edge.
  • This crystal and trim assembly is driven into a cylindrical bore of a support, such as a caseband, but this does not guarantee very good watertightness of the watch case during a deep dive.
  • the patent JP S53 124473 A describes a watch case with a crystal having an outer surface in a cylindrical shape on the top and a conical shape on the bottom to be fixed by means of a gasket in an opening in the cylindrical caseband. Since the surface of the caseband does not have a shape complementary to that of the crystal, the fixing by means of the gasket of the crystal in the caseband cannot ensure very good watertightness during a deep dive.
  • the main aim of the invention is therefore to overcome the drawbacks of the prior art described above by proposing a waterproof watch case suitable for withstanding high water pressure for diving to great depths underwater.
  • the present invention relates to a waterproof watch case, which comprises the features of independent claim 1.
  • An advantage of the waterproof watch case is that the crystal is fixed to the caseband by means of a one-piece metal gasket and with inclined contact surfaces of the caseband and the crystal.
  • the metal fixing gasket has a shape complementary to the fixing surfaces before the operation of fixing the crystal to the caseband.
  • conical support surfaces are provided on the crystal and the caseband, or even on the back mounted on an opposite side of the caseband. In this way, pressure forces on the crystal and the backband are transmitted to the caseband via conical support surfaces and via the one-piece metal gasket.
  • the fixing of the crystal to the caseband via the fixing gasket can be done in particular by hot forming. This makes it possible to avoid stress concentrations, to achieve good holding of the crystal and to achieve very good sealing of the watch case.
  • the heated amorphous metal seal is in a softened state in order to apply well to the contact surface of the crystal and the contact surface of the caseband, filling any gap in the surface condition of each surface. contact.
  • the amorphous metal gasket serves as a stress interface between the caseband and the crystal as the thermal expansion coefficient of the caseband, for example in titanium, is greater than that of the crystal, for example in sapphire.
  • FIGS. 1a and 1b represent an embodiment of a watch case 1, which can be used for a diving watch.
  • the watch case 1 essentially comprises a crystal 3, which can be made of sapphire or mineral glass, fixed on an upper side of a caseband 2, and possibly a back cover 4 mounted on a lower side of the caseband 2.
  • a bezel 7 can also be mounted on the upper side of the caseband 2.
  • a watch movement or module 10 is arranged in the watch case 1 in a casing ring 8, and at least one control member not shown can be mounted in a sealed manner in the rest position on or through the caseband 2 for setting the time, date or other functions of the diving watch.
  • the solid back cover 4 may comprise an annular edge 14 with internal threading to be screwed onto a thread 26 on the lower side of the caseband 2.
  • An annular bearing surface 24 of the back cover 4 comes into contact with an annular inner surface 32 of the caseband 2 of a shape complementary to the bearing surface 24 when the back cover 4 is mounted on the caseband 2.
  • the bearing surfaces 24 and inner surfaces 32 are inclined at a determined angle relative to an axis perpendicular to a plane of the watch case 1.
  • the surfaces 24, 32 are conical in shape and inclined towards the inside of the watch case 1 at a determined angle relative to a central axis of the watch case 1.
  • each cone shape is in the direction of the inside of the caseband 1.
  • watch case 1. The lower side of the caseband 2 further comprises an annular groove 16 housing a toric-shaped sealing gasket 6 in contact with the support surface 24 when the back cover 4 is mounted on the caseband 2.
  • the angle can be of the order of 60° ⁇ 5° relative to the central axis. This allows for a good distribution of stresses between case back 4 and case 2 due to water pressure when diving to great depths underwater.
  • the crystal 3 comprises an annular peripheral surface 13 to be fixed by means of a single-piece metal fixing gasket 5, 5' on an annular inner surface 12 on the upper side of the caseband 2.
  • the annular inner surface 12 is preferably of a shape complementary to the annular peripheral surface 13.
  • the gasket 5, 5', as an interface between the caseband 2 and the crystal 3, can also be produced before the fixing operation with a shape complementary to the contact surfaces of the crystal 3 on the caseband 2.
  • the annular peripheral surface 13 of the crystal 3 is inclined by a defined angle smaller than 90° relative to an axis perpendicular to a plane of the watch case 1.
  • the annular inner surface 12 is inclined generally towards the inside of the watch case 1 by the same angle as the annular peripheral surface 13 relative to a central axis.
  • the peripheral inner surface 13 and the annular inner surface 12 are of conical shape and inclined at a defined angle towards the inside of the watch case. This means that the apex of each cone shape is in the direction of the inside of the watch case 1.
  • the defined angle of inclination of the surfaces 12 and 13 can be of the order of 43° ⁇ 5° relative to the central axis. This makes it possible to have a good distribution of the stresses between the crystal 3 and the caseband 2 due to the pressure of the water during a dive to great depths underwater.
  • the single-piece metal fixing gasket 5, 5' is made of amorphous metal or metallic glass or amorphous metal alloy. It may comprise a first part 5 and a second part 5'.
  • the fixing gasket 5, 5' is of annular shape for the hermetic closure of the crystal 3 on the caseband 2.
  • the first part 5 of the gasket is of conical shape, while the second part 5' is cylindrical.
  • the length of the first part 5 in cross section may be of the order of 5 mm, while the height of the second part of the seal 5, 5' may be of the order of 2.5 mm.
  • the thickness of the seal may be of the order of 0.65 mm.
  • the single-piece metal gasket 5, 5' for fixing in an annular shape is made of an amorphous metal alloy so as to fix the crystal 3 to the caseband 2, for example by hot deformation.
  • the aim is to completely fill the space between the crystal 3 and the caseband 2.
  • the surface condition of the contact surface of the crystal 3 and the contact surface of the caseband 2 is replicated by the gasket softened by the heat. It may therefore be envisaged to have a certain roughness at the annular peripheral surface. 13 of the crystal 3 sufficient to have a better adhesion of the gasket 5, 5' to the crystal 3 and to the caseband 2.
  • the amorphous metal gasket softened by the heat completely matches the surface condition of the crystal 3 and the caseband 2, which guarantees a good hermetic closure.
  • the metal also compensates for any possible angle defect between the conical surface of crystal 3 and the conical surface of caseband 2, and thus ensures perfect support between crystal 3 and caseband 2, which greatly reduces stress concentrations during pressurization. This is very important because crystal 3 is generally made of a fragile material, such as sapphire or mineral glass. Thus, very localized contact of crystal 3 on caseband 2 risks causing breakage during pressurization underwater.
  • the gasket 5, 5' made of amorphous metal serves as an interface between the caseband 2 and the crystal 3.
  • this gasket also serves as a stress accumulation during the cooling operation. This is important because the thermal expansion coefficient of the titanium caseband 2 is greater than the contact surface of the sapphire crystal 3.

  • the platinum-based amorphous metal alloy may comprise Pt(57.5%), Cu(14.7%), Ni(5.3%) and P(22.5%). It may also be provided to produce the single-piece metal joint 5, 5' in an amorphous metal alloy mainly based on palladium (Pd, which makes it possible to form the joint at a temperature above 300°C.

  • the caseband 2 whose mechanical properties (e.g.
  • the fixing of the crystal 3 to the caseband 2 by means of the gasket 5, 5' is done at a temperature of the order of 380°C by applying a pressure of approximately 10,000 - 80,000 N for 30 - 250 seconds.

  • Another way to reduce the stresses in the crystal 3 after the assembly process, as described above, is to partially or completely crystallize the gasket 5, 5' in amorphous metal. Indeed, the crystallization generates a reduction in the volume of the amorphous metal and therefore of the gasket 5, 5', which slightly separates the caseband-gasket and gasket-crystal contact surfaces.

  • the crystallization of the 5, 5' joint can be done by maintaining the assembly at a prolonged temperature after the forming phase. For example, in the case of a zirconium-based alloy, maintaining it at 480°C for 5 minutes can generate crystallization of the joint. It is also possible to increase the temperature from 20°C to 100°C after the creep phase in order to accelerate the crystallization or to modify its nature (different crystalline phases). It is also possible to reduce the temperature after the creep phase in order to obtain a slower and finer crystallization.
