Abstract: A wristwatch including a watch case, a bezel mounted to rotate on the watch case, and a dial including at least one luminous index. The luminous index is illuminated through the dial by at least one light source disposed underneath the dial and powered by an electrical energy source. An activation component for activating the light source is housed inside the rotating dial and cooperates with a detection element housed inside the watch case. The activation component, in a determined position of the rotating bezel, detects presence of the activation component by the detection element. The detection element then emits an electrical signal addressed to a microprocessor circuit housed inside the watch case. The microprocessor circuit emits in response to reception of the electrical signal emitted by the detection element an electrical signal that activates lighting of the light source for a determined period of time.

Abstract: A timepiece including a case middle, a bezel, rotatably mounted on the case middle, and an actuation member including a cover capable of adopting a retracted position and a deployed position relative to the case middle, the cover being provided with a bearing surface actuatable by the user's finger, wherein the cover includes a shoulder distinct from the bearing surface, the shoulder being intended to cooperate with the bezel when the cover is in the retracted position.

Abstract: The method makes it possible to produce a decorated element for a timepiece or piece of jewelry. This decorated element may be, for example, a watch dial. The method includes the steps of taking a base substrate, and micromachining on said base substrate a mould or decorative partitions in a programmed pattern, and filling the mould or the decorative partitions with at least one filler material to obtain the decorated element. The filler material may be enamel.

Abstract: A palladium-based alloy including, expressed in weight, between 50 and 55% of palladium, between 45% and 50% of rhodium; a quantity x of silver where 0%?x?5%, and a quantity R of a balance including at least one element selected from among iridium, ruthenium, platinum, titanium, zirconium and rhenium and combinations thereof, where 0%?R?5%. The invention also relates to a A timepiece or piece of jewellery including at least one component made of such an alloy.

Abstract: Clasp for a watch bracelet or for a garment belt comprising at least two unfolding arms articulated to each other; a first unfolding arm comprises a first end attached to a bracelet strand and a second end pivotally articulated to a first end of a second unfolding arm; a second end of the second unfolding arm is traversed by an arbour about which there is articulated a cover provided with first and second flaps and to which another bracelet strand is attached; the clasp also comprises a push button fastening system, characterized in that at least one push button controls a bolt pivotally mounted on the cover; the bolt comprises a first hook devised to cooperate with a second hook fitted to the first unfolding arm and to keep said second hook locked when the push button is not being manually activated, the first hook being kept engaged with the second hook by an elastic means.

Abstract: A clasp for a watch bracelet or for a garment belt includes at least two unfolding arms articulated to each other, a first unfolding arm includes a first end attached to a bracelet strand and a second end pivotally articulated to a first end of a second unfolding arm, a second end of the second unfolding arm is traversed by an arbour about which there is articulated a cover with first and second flaps and to which another bracelet strand is attached. The clasp includes a push button fastening system, including at least one push button that controls a bolt pivotally mounted on the cover, the bolt includes a first hook cooperating with a second hook fitted to the first unfolding arm and keeping the second hook locked when the push button is not manually activated, the first hook being kept engaged with the second hook by an elastic structure.

Abstract: A decorative piece including a support made of a material having no plastic deformation in which at least one hollow is arranged. The hollow is filled with a first material forming a substrate in which at least one housing is arranged, the at least one housing configured so that at least one aesthetic element can be housed therein.

Abstract: A decorative piece includes a support made of a material having no usable plastic deformation in which at least one hollow is arranged. The hollow is filled with a first material forming a substrate in which at least one housing is arranged. The housing is arranged so that at least one aesthetic element is housable therein. The substrate further includes a gripper elastically deforming to retain the aesthetic element in the housing. The gripper further includes at least one setting element. A method for setting an aesthetic element on a support includes taking a support provided with at least one hollow, taking at least one aesthetic element, filling the hollow with a first material, making a setting hole and a gripper in the first material, and setting the aesthetic element by placing it in the hole and by deforming the gripper so as to retain the aesthetic element.
