The present invention concerns a device for performing operations on timepiece movements including a plate mounted on a stand, said plate including at least one storage area capable of receiving timepiece movement components, characterized in that said plate further includes at least one work support provided with means for holding timepiece movements, the work support being arranged to form an extension so as to facilitate access to said movement.

The invention relates to a photography system and to a method of generating a multi-view picture of a wristwatch.

A method for making and decorating top and bottom surfaces of a transparent timepiece component, the method including: depositing a first decoration on a male pattern; moving the male pattern, covered or not covered by a preform, into an injection chamber and injecting a transparent material therein to coat the male pattern to obtain a compound including the top face with the first decoration, on the bottom face; polymerizing the first compound in the injection chamber and then removing therefrom; depositing another material and/or second decoration in a cavity and held by gravity, and deposited on the top surface via a relative motion in the direction of gravity, to obtain a second compound.

Method for treatment of timepiece components on a rack including the steps consisting in: equipping said rack with grippers made of the same shape memory alloy, and each arranged to return to a reference shape above a martensite finish temperature specific to said alloy; bringing said rack to a temperature higher than said martensite finish temperature; bringing said rack equipped with said grippers to a preparation temperature; loading said rack with a batch of said components to be treated; performing said treatment on said rack loaded with said batch; unloading said rack.

Rack comprising grippers made of shape memory alloy, arranged to return to a reference shape above a martensite finish temperature specific to said alloy.

A method for assembling an insert with a recess of a structure, using a propulsion tool guiding a striker slide pushing a striker, and including a distributor device for controlling the forwards or backwards motion of the striker slide, and a tube guiding the striker and including a head with an internal profile adapted to the insert to be produced, a bar of material is inserted into the tube and heated to a predetermined temperature, a propulsion fluid is injected and a distributor slide is operated to move the striker slide at a predefined speed and to drive the striker to strike the preheated bar, force it into the recess and deform it so that it occupies the volume of the internal profile of the head.

A support frame for a sintering step of a method for producing a part, in particular for watchmaking, from a green body having an initial shape, the body shrinking from the initial shape to a final shape during the sintering step, the support frame having at least one face for supporting the body during the sintering step, wherein the geometry of the supporting face is in relief and configured to support the body from its initial shape into its final shape, so that it retains its shape and proportions in line with a shrinkage coefficient related to the sintering operation. The disclosure further relates to a sintering method using this support frame.
