Abstract (en)

[origin: WO2021058213A1] A method for attaching a horn on a middle of a watch, a horn/middle connection device and a horn/middle assembly, the horn comprising a first connector and the middle comprising a second connector having an undercut groove, the first connector interacting with the second connector in order to attach the horn on the middle. The method comprises: ○ placing the first connector of the horn in contact with the second connector of the middle, in such a way that one or more intermediate cavities are formed between the undercut groove and the first connector; ○ melting a part of the first connector of the horn in such a way as to create a molten material; ○ at least partially filling the one or more intermediate cavities by movement of the molten material; and ○ solidifying the molten material so as to rigidly connect the horn and the middle.
