A gold alloy may contain, by weight, between 73% and 77% of gold, between 5% and 11% of silver, between 1% and 7% of palladium, and between 10% and 18% of copper. The gold alloy may include iridium, rhenium, and/or ruthenium in up to 0.05 wt. %. The gold alloy may have an a* value in a range of from 3 to 9, and a b* value in a range of from 12 to 18, in CIELAB color space. A timepiece, piece of jewelry, or gemstone jewelry, may be made of such a gold alloy.

Timepiece, piece of jewellery or gemstone jewellery made of gold

A method for manufacturing a timepiece component. The method includes: providing a timepiece component (1); breaking the timepiece component (1) into a plurality of pieces (10); and depositing the pieces (10) on a support (2) and creating a desired pattern to be reassembled having interstices (1). The support (2) is then transferred into a mould and a preform (3) is placed on the pieces (10). The assembly is then heated to a temperature higher than the vitreous transition temperature of the preform (3) and a force is applied on the preform to fill the interstices (11) and obtain a reassembled timepiece component (1'). The assembly is then cooled below the vitreous transition temperature of the preform (3) to form the reassembled timepiece component (1′) whereupon the timepiece component (1′) is machined to the required dimensions.

Method for manufacturing a timepiece component

A component for the internal parts or the movement for a timepiece or a piece of jewellery including a substrate partially coated with a black layer and decorated with at least one stone, the black layer including carbon nanotubes or aluminium oxide, the substrate being at least devoid of the black layer on the portion facing the stone. It also relates to the method for manufacturing this component for the timepiece or the piece of jewellery.

Black component decorated with stones and manufacturing method thereof

A platinum alloy consisting, by weight, of the following elements: 95.00 to 96.00% of Pt, 1.00 to 4.95% of Ru, 0.05 to 2.00% of Ge, 0 to 2.00% of Au, any impurities with a total content 0.50%.

Platinum alloy

A clasp for a wristlet, the clasp including at least one set of four arms hinged with respect to each other so that the clasp can pass from a first position, referred to as the deployed position, wherein the arms are oriented radially towards the outside of the wristlet, to a second position, referred to as the closed position, wherein the arms are folded against each other so as to be placed under the wristlet, this set of four hinged arms including two sets of compasses formed by two arms joined by a hinge, the free end of the arms being mounted pivotally, on a first and on a second part of the wristlet.

Clasp for wristlet or belt

A dial configured to be mounted in a watch case, includes a plate made of a fragile material, the plate defining a horizontal plane and including at least one housing defining a point of attachment for at least one foot formed of a body and a head arranged to rest inside the at least one housing, the foot includes a circular slot arranged to receive a ring-like element made of a shape memory alloy able to move from a retracted position to an open position in which the foot is mechanically held in the housing.

Dial made of non-conductive material with feet

A setting or mounting includes a ring carrying elements for setting a decorative element, this setting or mounting being arranged to be placed radially inside a hollow provided in a substrate of an item to be decorated. The setting includes a circular slot arranged to receive a ring-like element made of a shape memory alloy which can undergo a reversible transformation. The ring-like element is able to move from a retracted position in which it rests in the slot, to an open position in which the ring-like element at least partially protrudes from the slot to hold the setting in the substrate.

Decorative element made by a setting technique

The invention relates to a decorative part () including several stones () and a device (') for securing the stones () in relation to each other. According to the invention, the securing device (&#x2032;) includes a single electrodeposited base (&#x2032;) whose shape matches one part of the stones, thus allowing all the stones () to be attached in relation to each other without any stress, and the girdles () of the stones () are mounted edge-to-edge in relation to each other so that the single base is concealed. The invention also relates to the method for manufacturing a part () of this type.
