Definitions

  • the present invention relates to a timepiece, and it relates more particularly to new developments relating to transparent and visible elements from the outside of the part, such as for example glass.
  • Document EP-A 0 066 538 describes a watch in which the crystal is welded to the middle part by means of a layer of low-melting solder, which adheres to the crystal by means of a coating serving both a bonding layer and a solder masking layer.
  • the object of the present invention is to propose a timepiece of which a transparent element visible from the outside can be subjected to another element by a high temperature welding, and in which the transparent element is capable of receiving an outer decorative layer of hard material, as well as its manufacturing process.
  • the invention makes it possible to reach breaking loads when the coating is torn off greater than 147 x 106 N / m 2 (15 kg / m m 2 ) which become comparable to the tensile strength of the sapphire itself. even, which is between 186 and 490 x 10 6 N / m 2 (19 and 50 kg / mm 2 ) depending on the direction of the tensile force.
  • FIG. 1 there is shown a partial section of a sapphire crystal or mineral glass 1 forming a component of a timepiece according to the invention.
  • This glass 1 comprises in particular an adherent coating 2 ensuring the attachment of an outer decorative layer 3, and an adherent coating 4 ensuring the attachment of a layer of high temperature solder material 5.
  • the decorative layer 3 is made of a hard material, for example metallic, of the carbide or titanium nitride type which, in addition to their high hardness which allows them to retain a shiny appearance due to their non-scratchability, have shades very close to those of gold.
  • a hard material for example metallic, of the carbide or titanium nitride type which, in addition to their high hardness which allows them to retain a shiny appearance due to their non-scratchability, have shades very close to those of gold.
  • other materials could be used, and in particular carbides, borides or nitrides of metals such as tantalum, tungsten, chromium or other compounds having an adequate appearance and hardness.
  • the adherent coating 2 it may comprise a single layer adhering to the glass and ensuring a good bond with the decorative layer 3 or several layers 6, 7 having good cohesion between them, the bottom layer 6 adhering to the glass 1 and the outer layer 7 adhering to the decoration layer 3.
  • the layer 6 can be formed of aluminum oxide AI2 0 3 , the layer 7 being a layer of chromium and the decorative layer 3 being formed of titanium nitride.
  • the adherent coating may be formed of titanium oxide Ti0 2 , which is subsequently coated with nitride or titanium carbide TiN or TiC.
  • the adherent coating 4 may consist of one or more layers (8, 9, 10) superimposed on different materials.
  • the layer 8 ensuring the attachment of the coating on the ice 1 is constituted by aluminum oxide AI2 0 3
  • the layer 10 ensuring the attachment of the solder layer 5 is a layer of tungsten carbide
  • an intermediate layer 9 of tungsten provides the connection between the two layers 8 and 10.
  • oxides for the layer in contact with the ice has proved to be particularly advantageous.
  • high temperature solder material forming the layer 5 is meant a filler material capable of being applied in the solid state between the coating 4 and another element of the timepiece, then brought to melting at a temperature of the order of 550 ° C to 600 ° C or more, depending on the nature of the elements to be combined, so as to form a permanent bond between these elements after cooling.
  • Such materials are widely used and used for example for welding steel parts. Their breaking load is much higher than that of welding materials at low temperature, and most often greater than 588 x 10 6 N / m 2 (60 kg / mm 2 ). Their resistance to oxidation under normal conditions of use of a timepiece is also much higher.
  • FIG 2 there is shown in partial section a watch case 11 provided with a crystal 12 on which have been fixed an outer decorative layer 13 and an annular middle part 14 welded to the crystal 12 by means of a solder layer 15.
  • the glass has been prepared in accordance with the preceding explanations to allow the attachment of layers 13 and 15.
  • a base 16 is removably mounted under the middle 14 by means of screws 17.
  • the fixing by welding of the middle part 14 on the glass 12 can be obtained, after the production of the adherent coatings on this glass, by placing the welding material 15, which for example forms a frame of suitable dimensions, between the two parts to be assembled, then by placing the assembly thus formed in an induction furnace.
  • Figures 3 and 4 showing a coated glass according to the invention in top view, and they illustrate the cases where a decorative layer forms either an annular frame 18, or false bezel, on the periphery of the glass, which can be bevelled as in FIG. 1, either fancy patterns 19 intended, for example, to hide the elements for fixing the glass of FIGS. 5 and 6.
  • FIGS 5 and 6 there is shown respectively in partial section and in top view a watch case in which the crystal 28 is removably attached to a middle part 29 by means of fasteners 30, four in number for example, welded at high temperature under the crystal, and which have hooking surfaces 31 collaborating elastically with protuberances 32 of the inner surface of the middle part 29 to maintain the assembly.
