Bench for disassembling a watch with secured fastening

A watchmaking set comprising:

• a disassembly bench for unlocking and disassembling a first component and a second component of a watch with secured fastening comprising at least two slides for immobilising said first component and said second component in a locked position, wherein said disassembly bench comprises:
• handling devices arranged to transmit a relative disassembly movement between said first component and said second component, and
• centrifuging devices for simultaneous application of a centrifugal force to all said slides and pneumatic or hydraulic devices to apply an overpressure or an underpressure to the watch to press all said slides into a position of free passage, wherein an action of said handling devices is only possible when all said slides are in said position of free passage;
• and
• said watch with secured fastening, which has said first component and said second component, which are arranged to be fitted together in a complementary manner respectively through a first surface and a second surface, and indexed in assembly position by at least two pairs comprising first indexing means of said first component and second indexing means of said second component that are complementary to one another or to such a respective slide of said at least two slides within each respective pair of said at least two pairs, and said first indexing means and second indexing means of each respective pair of said at least two pairs are aligned two by two in said assembly position to define a chamber, in which a each respective slide of said at least two slides is movable between said position of free passage and a locked position, in which said slide is arranged to lock said first component and said second component,
• wherein, in said locked position of said first component and said second component, in at least one of said at least two pairs, said first indexing means, the second indexing means, and a respective slide of the at least two slides are inaccessible to any tool,
• wherein said centrifuging devices and said pneumatic or hydraulic devices are arranged for simultaneous application of said centrifugal force and/or said overpressure and said underpressure to each said chamber, and
• wherein only the simultaneous application to each said pair of the at least two pairs belonging to said watch of a centrifugal force by said centrifuging devices or a pressure variation by said pneumatic or hydraulic devices actuates a release movement of each said slide of the at least two slides in each said pair of the at least two pairs belonging to said watch to allow the unlocking of said first component and said second component and to permit a relative movement between said first component and said second component under the action of said handling devices.
