A method for depositing a rare material in a thin layer at the surface of an horological or jewellery external part includes providing a rough part of rare material, shaping the rough part of rare material so that it is adapted to be used as a target part for a PVD method, depositing material of the target part at the surface of a substrate consisting of an horological or jewellery eternal part by a PVD method so as to cover the external part.

A decorative article has a substrate of which at least part of the surface is configured with Ti or stainless steel; and a coating made of primarily TiC and disposed on the substrate. The coating has at least a first region, and a second region disposed closer to the substrate than the first region. The elastic modulus of the second region is greater than the elastic modulus of the first region.

A wristwatch includes a main unit, a first design belt detachably attached to the main unit, an identifier that identifies the first design belt, a display device that displays the display content, a memory that stores the display content displayed on the display device, and a display control unit that displays the display content corresponding to the first design belt identified by the identifier on the display device.

The method makes it possible to produce a decorated component for a timepiece or piece of jewellery. This component provided with the decoration may be, for example, a watch hand. To produce said component, a base substrate is used and a micromachining operation is performed on or in the base substrate to obtain an upper part of the component, which is provided with the decoration. The decoration is produced through the thickness of the upper part and in a programmed pattern. Thereafter, the upper part is placed on a luminescent or colored substance to obtain the component.

In a crown for a timepiece including a crown body having a recess formed therein and a decorative jewel fixed into the recess, a bonding agent is disposed between the inner side surface of the recess and the decorative jewel, and the depth dimension of the inner side surface is at least 0.5 mm.

The present invention relates to a method for manufacturing a part comprising at least one three-dimensional metallised pattern overlying a local enamel underlayer.

A watch dial includes a substrate, a protruding portion formed on the substrate by laser machining, and a coating layer provided around the protruding portion. At least a portion of an upper surface of the protruding portion is exposed from the coating layer.

A decorative, wearable system includes at least one decorative element mechanically and moveably suspended in a liquid by mechanical fixation elements and actuated by invisible mechanism(s). The liquid shares a substantially similar refraction index as at least one of mechanical fixation elements and/or actuation mechanisms.

A method for producing a three-dimensional element on a timepiece component, in particular on a dial, that includes generating, by means of a control unit, at least one control instruction for a printing device for reproducing a reference digital graphical representation relating to said three-dimensional element, and constructing, by means of the printing device, at least two substantially superimposed or superimposed layers each having at least one particle which is printed on the timepiece component and which forms the three-dimensional element.

An item made from cermet and/or ceramic, and in particular a bezel (1) of a timepiece, produced by a method for injecting at least two materials (2, 3) of distinct compositions, the item including a part (4) where the two materials (2, 3) are superimposed and are interleaved one in the other.
