Claim 6:
7. A method for manufacturing a part comprising a support made of an electrically non-conductive material, said support being provided with at least one recess filled with an aesthetic element made of an electrically conductive material, said aesthetic element forming a decoration on a side of the part that is configured to be visible, the method comprising:
providing the support having said at least one recess and providing a preform configured to form the aesthetic element of the part;
inlaying by pressing the preform into said at least one recess in the support; and
electrochemically treating the surface of the aesthetic element, wherein a recess of said at least one recess opens in two or more places onto a side of the part that is configured to be non-visible, to respectively form one or more contact points for carrying current across the aesthetic element during the surface treatment,
wherein the part is a watch case middle forming the support with said at least one recess filled with the aesthetic element forming a portion of the case middle,
wherein the portion of the case middle extends up to a horn of the case middle, and
wherein a recess of said at least one recess communicates with a hole for insertion of a spring bar arranged in the horn of the case middle.
