A lathe including a moving headstock designed to rotate and move forward a workpiece to be turned in relation to an axis of translation and rotation. A guide bush is designed to be attached to a frame of the lathe and includes a bush spindle and a clamping mechanism. The guide bush is designed to operate either in bush mode or in grip mode and is designed to be moveable axially in relation to the frame along the axis of translation and rotation. The lathe is arranged to operate in a first mode in which the guide bush is driven axially by the moving headstock, and a second mode in which the axial position of the guide bush is static in relation to the frame.

An ergonomic watchmaker's workstation includes, around a work platform, two forearm supports each at least tiltably adjustable in a vertical plane, and control and storage unit arranged to control motorized adjuster in order to move each of the forearm supports in at least one degree of freedom. The control and storage unit are programmable to trigger, at predefined or random moments, micro movements of the forearm supports of short duration, less than two seconds, and of small angular amplitude, less than 2 and/or of linear amplitude, less than 5 mm. The workstation further includes a user interface connected to the control and storage unit, to trigger other micro movements, and/or to modify the settings.

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.

Ergonomic watchmaker's workstation including, around a work platform, two forearm supports each at least tiltably adjustable in a vertical plane, and control and storage means arranged to control motorised adjustment means in order to move each said forearm support in at least one degree of freedom, and said control and storage means are programmable to trigger, at predefined or random moments, micro movements of the forearm supports of short duration, less than two seconds, and of small angular amplitude, less than 2 and/or of linear amplitude, less than 5 mm, the workstation further including a user interface connected to the control and storage means, to trigger other micro movements, and/or to modify the settings.

A gripper (100) with radial clamping, provided for a timepiece component, including a plurality of jaws (1) distributed about an axis (D), which defines a direction of insertion and/or of extraction for the timepiece component, and connected to a support (2) of the gripper, each jaw including a bearing surface (10) arranged to ensure a radial contact, relative to the axis, with a counter surface of the component and to be able to apply on this counter surface a radial clamping force, at least one the jaw being radially movable, in relation to the axis, and having an essentially radial travel in relation to the axis (D). Each mobile jaw is connected to the support by a radial elastic return member (3) that extends in a general plane (P) perpendicular to the axis and that is arranged between the mobile jaw and the axis (D).
