Claims10
A method for manufacturing an applique, the applique includes an upper surface and a rim intended to be seen by a user, a lower surface for its resting on a dial or a structure of a timepiece and at least one foot protruding from said lower surface, the method comprising:
- producing a base in a metal material, said base having an upper face and a lower face;
- machining the upper surface and the rim of the applique in the base from the upper face, with a predefined depth P;
- washing the machined base;
- depositing a varnish layer on the machined upper face of the base so as to cover the upper face, the upper surface and the rim of the applique;
- drying the varnish layer;
- depositing a glue layer on the upper face of the base, over at least the entire machining depth, said glue layer being superimposed on the varnish layer, and the glue is dried;
- machining the lower surface and the at least one foot of the applique via the lower face of the base to a depth P′, the depth P′ is greater than a total thickness E of the base less the machined depth P of the upper face, wherein a depth of the at least one foot is less than the depth P′;
- plunging the base into a bath of a liquid solution in order to dissolve the glue and release the applique;
- packaging the applique in view of its delivery.
