A method for manufacturing a timepiece component includes: forming a first processed surface having a predetermined pattern by irradiating a surface of a receiving plate with a femtosecond laser; and forming a second processed surface having a surface roughness smaller than that of the first processed surface by irradiating at least a part of the first processed surface with a nanosecond laser.

Provided is a timepiece including, in addition to a crystal, the following external elements: a back (2), a middle part (1), a dial (3), and two bracelet strands (30), at least one of these external elements includes a body formed of a first portion made of a first opaque material and of a second portion made of a second partially transparent or translucent material. The first material being integral with the second material and the timepiece also includes at least one light source (10) producing light which passes through the second portion made of a partially transparent or translucent ceramic material comprising zirconia.

Horological display mechanism (100) for a timepiece (1000), comprising at least one three-dimensional display support (10), which is arranged for the simultaneous display of at least a first variable on a first three-dimensional display (901) under the action of a first control mechanism, and of a second variable on a second three-dimensional display (902) under the action of a second control mechanism, wherein the first display (901) surrounds the second display (902), or vice-versa, and wherein the first control mechanism and the second control mechanism are capable of being manoeuvred independently of one another, and constitute separate mechanisms, one for controlling the translational motion and the other the rotational motion, or vice-versa.

The present invention relates to a mechanical stop and start system for a function of a timepiece, comprising a mass, mounted so as to be able to move on a frame, between a first and a second end position, these being defined respectively by a first stop and a second stop, said mass moving in a bistable manner, under the effect of gravity, tensioning a spring between the first and second end positions, and relaxing said spring between the second and first end positions.

Horological display mechanism (100) for displaying variables on separate unit display supports (10), each enclosing a display indicator (901; 902) which is a first display (901) capable of moving in translation, or a second display (902) capable of moving in rotation, all of these unit supports (10) comprise indicators (901; 902) of the same kind, which are either first displays (901) for displaying a first variable, or second displays (902) for displaying a second variable, or both first displays (901) and second displays (902), all visible to the user, the display mechanism (100) comprises a control mechanism (300) arranged to drive wheels or rod systems for driving the different display wheel sets and comprises a first carrier (111) for driving, by itself, all of the first displays (901), and/or a second carrier (112) for driving, by itself, all of said second displays (902).

The present invention relates to a timepiece component comprising on at least one part of its surface a coating formed of one or more layers of organic pigments.

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.

A timepiece includes a representation of a non-rectilinear object, the representation particularly including a movable element kinematically connected to a drive mechanism. The representation also includes at least one second movable element, the drive mechanism being arranged such that the movable elements each move, simultaneously and in synchronization, between a first and a second end position, and vice versa, the movable elements forming the representation at a first size and at a second size greater than the first, respectively, when the movable elements are in the first and second end positions thereof.

A minute hand includes an upper surface, a lower surface that is in a front-back relationship with the upper surface, and a first side surface coupling the upper surface and the lower surface, and the first side surface is provided with decoration including a recess and a protrusion.

A timepiece display device including a first display element and a second display element superimposed above a fixed part including a main bearing surface, this second display element is subjected to opposing forces exerted, on the one hand by lower return means which tend to bring the second display element closer to the first display element, and, on the other hand, by upper return mechanism which tends to move the second display element away from the first display element without contact between them or else by mechanical spacing device which includes a bearing surface providing a stop bearing function on a stop surface of the second display element, to limit the travel from the second display element to the first display element.
