A method for fabrication of a part intended to be welded including a step for forming an oblique wall between two perpendicular surfaces capable of reducing the contact surface of the face to be welded.

Process for manufacturing a hybrid timepiece component, comprising structuring at least one wafer (14) of a first micromachinable material so as to form at least one through-opening (15) within the wafer (14), said structured wafer (14) being intended to form a first part (4) of the hybrid timepiece component; and depositing a metal by electroforming, so that the metal extends through the through-opening (15) and over the two upper and lower faces of the wafer (14) as a single piece resulting from one and the same electroforming step, the electroformed metal being intended to form a second part (8) of the hybrid timepiece component.

The invention relates to a fabrication method including an assembly step for inserting an intermediate part intended to ensure the flatness of the face to be welded.

A display hand intended to equip a timepiece, including a body and a pipe, providing an arbor hole arranged for fitting the display hand onto a drive arbor. The body is made of a composite material, the pipe includes, over all or part of the outer periphery, a surface for connection to the hand body to ensure the adhesion of the composite material to the pipe.

Timepiece display mechanism including a cam driven by a time base, and a pivoting lever including an elastically returned feeler member following the contour of the cam and a first rack meshing with a first angular orientation wheel which drives an indicator plate synchronously or via a differential mechanism, the indicator plate projecting radially with respect to a main axis and being parallel to or coplanar with the first wheel, the display mechanism includes a connecting rod articulated at a first end to a carriage slidably mounted on the indicator plate and carrying a retractable hand, a second end of the connecting rod being pivoted on a fixed pivot or on a movable pivot comprised in an elongation wheel set driven directly or indirectly by the lever.

The invention relates to a timepiece component with a part comprising elastic attachment means and securing means arranged to be welded enabling the attachment of the elastic means to be decoupled from the securing means to ensure the welding of the timepiece component.

A display hand intended to equip a timepiece, including a body and a pipe, providing an arbor hole arranged for fitting the display hand onto a drive arbor. The body is made of a composite material, the pipe includes, over all or part of the outer periphery, a surface for connection to the hand body to ensure the adhesion of the composite material to the pipe.

A pointer device including a rotation body, a pointer shaft provided on the rotation body, a base member which rotatably supports the pointer shaft, and a spiral spring which has a substantially truncated conical shape and is arranged between the rotation body and the base member.

A pointer including a pointer body formed of synthetic resin, and a pointer attachment section formed of a material harder than the synthetic resin and provided in a rotation center portion of the pointer body, in which the pointer attachment section comprises a large-diameter section to which the pointer body is fixed and which includes a positioning section, and a small-diameter section which is provided coaxially with the large-diameter section and to which a pointer shaft is attached.

A pointer hand for a watchmaking part including a body and a cannon configured to be driven onto a cylindrical arbor, the cannon having an internal diameter that is greater than the diameter of the cylindrical arbor. The cannon includes a flat on its internal diameter that is configured to cooperate with the cylindrical arbor, to elastically deform the cannon on both sides of the flat to fix the hand onto the cylindrical arbor.
