Abstract: A wristlet including a first row with at least one central link, a second row and a third row disposed respectively on either side of the first row and each including at least one lateral link, a connecting rod positioned in the three aligned holes of the first, second and third rows. The lateral link is hollow and includes in its hollow an insert delimited by two external lateral walls, the connecting rod including at each end a first banking and a second banking respectively bearing on a portion of the external lateral wall when the lateral link pivots about the connecting rod so as to limit the amplitude of rotation of the central link about the connecting rod.

Abstract: A method is for manufacturing an ornamental part, for example a watch, jewellery or telephone part, in particular a watch crown. The part includes, at least partially, a hard material with a Vickers hardness exceeding 1,000 HV. The method includes the following main steps: producing a precursor from a mixture of at least one powder material with a binder, producing an insert made of a polymer material, the insert having, at least partially, a negative shape of that desired for at least one portion of the part, overmoulding the precursor onto the insert made of a polymer material by injection into a mould to form a green body, and sintering the green body to form a body of the future part from the hard material.

Abstract: A method for manufacturing a sapphire single-crystal, including melting alumina and/or sapphire in a crucible, and bringing the molten alumina and/or sapphire in contact with a monocrystalline sapphire seed to make the molten alumina and/or sapphire crystallise progressively according to a growth direction to form the sapphire single-crystal. The monocrystalline sapphire seed has a rhombohedral crystallographic structure defining three crystallographic axes [A], [C] and [M] perpendicular to each other and respectively perpendicular to the crystallographic planes. The monocrystalline sapphire seed is a plate delimited by two planar faces which extend parallel to and at a distance from each other, is obtained from an initial sapphire single-crystal which is cut so that one of the crystallographic axes of the monocrystalline sapphire plate forms with a normal to the planar faces of the monocrystalline sapphire plate an angle whose value is comprised between 5 and 85°.

Abstract: A method and device for manufacturing a bevelled stone, particularly for a timepiece are disclosed. A precursor is produced from a mixture of at least one material in powder form with a binder. The method includes pressing the precursor so as to form a green body, using a top die and a bottom die comprising a protruding rib, sintering the green body so as to form a body of the future stone in at least one material, the body including a peripheral face and a bottom face provided with a groove, and machining the body including a substep of planning the peripheral face up to the groove, such that an inner wall of the groove forms at least a flared part of the peripheral face of the stone.

Abstract: A method for colouring a part to be treated made of metal, this method including the step of implanting mono- or multi-charged ions in a surface layer of the part to be treated by directing towards this part to be treated a mono- or multi-charged ion beam produced by a source of mono- or multi-charged ions, the part to be treated changing colour under the effect of this ion implantation. A coloured metal can be obtained with the above method.

Abstract: A method is for manufacturing a part including a support made of an electrically non-conductive material, the support being provided with at least one recess filled with an aesthetic element made of an electrically conductive material, and the aesthetic element forms a decoration on a side of the part that is intended to be visible. The method includes inlaying by pressing a preform intended to form the aesthetic element into the at least one recess of the support, and treating the surface of the aesthetic element. The at least one recess opens in one or more places onto a side of the part that is intended to be non-visible, to respectively form one or more contact points for carrying current across the aesthetic element during the surface treatment.
