A disassembly bench is for unlocking and disassembling a first component and a second component of a watch with secured fastening including handling devices to transmit a relative disassembly movement between this first component and this second component. The bench also includes centrifuging devices and/or pneumatic or hydraulic devices for simultaneous application of a centrifugal force and/or an overpressure or an underpressure to such a watch to press into a position of free passage one or more slides arranged to immobilize this first component and this second component in a locked position. A watchmaking set includes such a disassembly bench and such a watch with secured fastening.

Forearm support for a watchmaker's bench, comprising: a coupling portion, arranged to be coupled to a watchmaker's bench, a first arm linked to the coupling portion, a second arm linked to the first arm, a forearm support pad, linked to the second arm, and arranged to support a forearm of an operator,
characterized in that the forearm support comprises an articulation system comprising at least: a first ball joint, arranged between the coupling portion and the first arm and connecting the coupling portion and the first arm, a second ball joint, arranged between the first arm and the second arm and connecting the first arm and the second arm.

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.

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.

Watchmaker's bench, comprising: a work table arranged to receive timepieces, a frame supporting the work table, defining at least one work face or a work station on the work table for an operator and arranged to rest on a workshop floor, characterized in that the watchmaker's bench comprises at least one mounting rail, particularly arranged below the working table and facing the work face or the work station, and arranged to receive at least one work module to be coupled to the watchmaker's bench in a position that is adjustable along said at least one mounting rail.
