  • the present invention relates to a cladding element 1 of a timepiece or watch 100 comprising a frame 2 made of a first material. On this frame 2, at least one cap 3 is fixed. This cap 3 is made of a sheet of a second material. This sheet is shaped to at least partially cover said covering element 1 by marrying its relief.
  • this frame 2 is a watch case 10 like the one visible in the figure 1 .
  • This watch case 10 essentially comprises a middle part 11 also serving as a bezel and also called middle-bezel, a mirror 13 attached to the middle-bezel.
  • the middle-bezel 11 is made of plastic, which leads to a very cheap watch and manufactured in large series. But the feeling of cheap may just disappear if the middle-bezel 11 is dressed by the cap made according to the invention.
  • the "Swatch" watch (registered trademark), known worldwide for its particular shape and its very low price, as well as for its goodness, can constitute the middle-case 11 mentioned above, middle-case 11 that would be covered with a cap 3 giving this watch a new aesthetic appearance without changing its reputation and without significantly altering its cost price.

  • the half bracelets 18, 19 can be replaced by a metal bracelet consisting of links and using a folding clasp system.
  • the ice 13 and the middle-bezel 11 may be made of materials weldable to each other.
  • the middle-bezel can, for example, be manufactured in one of the materials usually designated ABS (acryl butadiene styrene), ASA (acrylstyrene acryl-ester) or SAN (styrene acryl nitrile).
  • the ice is made of a transparent acrylic resin (PMMA) commonly referred to as "plexiglass". Of course, it is possible that the ice 13 is made of sapphire.
  • the second material of the cap 3 is an amorphous metal alloy. It will be understood that the term partially amorphous indicates that for a block of material, the percentage of the amount of material of said block having the amorphous state is sufficient for the block itself to have the specific characteristics of amorphous metals and metal alloys.
  • the second material may also be a totally amorphous metal alloy.
  • the amorphous materials have the advantage of being easily shaped.
  • the precious metal or one of these alloys is included in the list comprising gold, silver, and nickel.
  • the thickness of the sheet was chosen here to 0.3 mm, but other caps 5 with greater or lesser thicknesses could also be suitable.
  • amorphous metal alloys are their hardness properties. Indeed, a conventional crystalline steel used in horological applications has a hardness of the order of 200-300 Vickers. However, for metal glasses, this hardness is about 600 Vickers is 2 to 3 times more than for conventional steels. Therefore, the cap 3 amorphous metal alloy will be more resistant to blows and other shocks that it will undergo a cap of the prior art. Similarly, this hardness allows superior resistance to everyday scratches and thus allows longer to keep the shine of the cap 3.
  • amorphous metal alloys have an ease of shaping. Indeed, the amorphous metals have the particular characteristic of softening while remaining amorphous in a specific temperature range (T x - T g ) specific to each alloy. It is thus possible to shape them under a relatively low stress and a not too high temperature.
  • One method used is the hot forming of an amorphous preform.
  • This preform is obtained by melting the metal elements constituting the amorphous alloy in an oven. This fusion is done under control with the aim of obtaining a contamination of the oxygen alloy as low as possible. Once these elements are melted, they are cast as a semi product and then cooled rapidly to maintain the amorphous state.
  • the hot forming is performed in order to obtain a final piece. This hot forming is performed by pressing between two matrices in a temperature range between T g and T x for a predetermined time to maintain a totally or partially amorphous structure. This is done in order to maintain the characteristic elastic properties of the amorphous metals.
  • This process consists in molding the alloy obtained by melting the metal elements in an oven, in the form of any part such as a bar and that in a crystalline or amorphous state, it does not matter. Then this piece of any form of alloy is melted again to be injected into a mold having the shape of the final piece. Once the mold is filled, it is rapidly cooled to a temperature below T g in order to avoid crystallization of the alloy and thus obtain a cap 3 of amorphous or semi-amorphous metal alloy.
  • cap 3 amorphous metal alloy allows to have a frame 2 having complex shapes without this being a problem for the realization of said cap 3.
  • having a cap 3 amorphous metal alloy also allows to have a cap 3 easily decorated.
  • the shaping facilities of the amorphous metal alloy make it possible to easily decorate said cap 3.
  • An unrepresented example of decoration consists of a structuring of the surface for example to obtain a beaded effect or Cote de Genève or nails. Paris.
  • the replication properties of amorphous metal alloys are used.
  • the negatives of the desired structures are made on the walls of the dies used for hot forming. Therefore, during the hot forming operation, the viscosity of the amorphous metal alloy causes a perfect impression of these structures at the level of the amorphous metal alloy.
  • One advantage is that the operation of producing the cap 3 and the structuring operation of the surface of the cap 3 are done simultaneously.
  • FIG. 2 Another example of visible decoration at the figure 2 consists in crimping one or more decorative or aesthetic elements.
  • These decorative elements 20 are, for example, precious stones such as diamonds or zircons or rubies, but also ceramic or glass elements.
  • a hot crimping operation can be used. For this, the cap 3 is heated locally to the place where said aesthetic element 20 is to be inserted, at a temperature between Tg and Tx. Once the place has been warmed up, the decorative element 20 is pressed into the cap 3 of amorphous metal alloy. During the cooling of the amorphous metal alloy, the aesthetic element is trapped.
  • the decorative element is heated to a temperature greater than Tg and then pressed into the cap 3.
  • the heat released by the decorative element 20 locally heats the cap 3 to a temperature above Tg facilitating insertion.
  • the aesthetic element is trapped.
  • each material is characterized by its Young's modulus E also called modulus of elasticity (generally expressed in GPa), characterizing its resistance to deformation.
  • each material is also characterized by its elastic limit ⁇ e (generally expressed in GPa) which represents the stress beyond which the material plastically deforms.
  • the crystalline materials as used in the prior art for example, the Cu-Be alloy, whose Young's modulus E is equal to 130 GPa and having a yield strength ⁇ e typically equal to 1 GPa, gives a low ⁇ e / E ratio, that is to say the order of 0.007.
  • These crystalline alloy caps have, therefore, limited elastic deformation.
  • the ratio ⁇ e / E is increased by raising the elastic limit ⁇ e.
  • the material sees the stress, beyond which it does not return to its original shape, increase. This improvement of the ratio ⁇ e / E then allows a larger deformation.
  • fixing means 30 arranged at the level of the covering element 1.
  • These fixing means 30 comprise at least one flexible blade 31 extending from the cap 3 and having at its end a free hook 32.
  • This hook 32 is arranged to cooperate with a groove 33 located on the frame 2.
  • the fastening means 30 comprise two flexible blades 31 each cooperating with a groove 33 of the frame 2.
  • the fastening means 30 are in the form of rivets 37.
  • the fastening means 30 are arranged so that the armature 2 is provided with at least one riveting recess 35 and preferably at least two riveting recesses.
  • the cap 3 is made so as to have pins 36 or surplus material serving as rivets 37. These pins 36 are arranged on the outer surface of the cap 3. These pins 36 are arranged on the cap 3 so that when it is placed on the frame 2, the locations of the pins 36 and riveting recesses 35 are combined. It is understood that the number of pins 36 is identical to the number of riveting recesses 35.
  • hot forming is used and visible to Figures 5a to 5c .
  • This operation consists in locally heating the pins 36 of amorphous metal alloy with a tool 200 to a temperature between T g and T x so that the amorphous metal of the nipples 36 soften and become viscous. Then, it is sufficient to exert pressure on the nipples 36 with a tool 300 so that the amorphous metal alloy is inserted into the riveting recesses 35. After cooling, the amorphous metal alloy in the riveting recesses 35 solidifies while maintaining an amorphous state and the cap 3 is then attached to said frame 2.
  • An advantage of this alternative is that it is invisible to the user of the trim element 1, the attachment is not visible.
  • the frame 2 comprises several caps 3 as visible in the figure 6 it is preferably provided at least two pins 36 per cap 3.
  • the riveting recesses 25 can extend in different directions. Indeed, depending on the nature of the cap 3, if the riveting recesses 35 extend in the same direction, there is a risk that the cap 3 can be removed easily from the frame 2. With 35 riveting recesses extending in different directions, for example diverging, a retaining of the cap 3 is automatic. Likewise, complex shapes for the riveting recesses 35 may allow a better grip of the cap 3 on the frame 2.
  • the covering element 2 is a telescope 41 of a rotating bezel system 40 of a timepiece.
  • a system 40 actually comprises a telescope 41 which serves as a frame 2 and which is mounted on the periphery of the lens 13.
  • An indexing device 42 using a notched element 43 and a spring element 44 allows the bezel 41 to to be mobile, that is to say to be able to rotate.
  • a rotating bezel system 40 includes an annular rotating bezel 41 having an upper face and a lower face, the upper face being the face visible by the user.
  • This bezel 41 comprises, on its lower surface, a notch or toothing 44.
  • the rotating bezel system 40 further comprises a spring means 43.
  • This spring means 43 is inserted between the bezel 40 and the middle part 11 of the timepiece 100 when the bezel 41 is mounted forcibly on the middle part 11.
  • This spring means 43 is in the form of a flat ring comprising, on its face facing the notch 44 of the bezel 41, lamellae. These slats are arranged to have an inclination between 0 and 90 ° relative to the plane of the flat ring.
  • These slats have a certain elasticity so that the spring means 43 act on the bezel 41 to exert a vertical force which tends to push the bezel 41 out of the middle part 11 of the timepiece 100. These slats also serve to cooperate with the notching of the bezel 41.
  • the upper face of the bezel 41 serving as a frame 2 may be provided with a cap 3 giving a more rewarding appearance.
  • the cap 3 may cover the entire upper face of the bezel 41 as visible in FIG. figure 7 .
  • the covering element 2 is a bracelet composed of a multitude of links 50 hinged together.
  • This bracelet comprises two parts each consisting of a plurality of links. The two parts are interconnected by a folding clasp system and each comprise a terminal link 50.
  • This terminal link 50 is used to fix said strap part to the box 10 of the timepiece 100.
  • Each link 50 is then composed of a plate 51 acting as reinforcement.
  • This plate is rectangular and has a first face 52 extending in the direction of the length and a second face 53, parallel to the first face.
