Claim:
1. A method for manufacturing an electroformed structural timepiece component, the method comprising: selecting a first alloy including a first metal to make both inserts and an electroformed shell; making said inserts; forming a sacrificial electroforming substrate having a complementary profile to an inner profile of said timepiece component of a sacrificial material; forming housings on said sacrificial electroforming substrate; inserting said inserts into said housings made on said sacrificial electroforming substrate to form an equipped sacrificial substrate, arranging resists on said equipped sacrificial substrate; depositing an electroformed shell made of said first alloy on said equipped sacrificial substrate, which acts as an electroforming core to form said electroformed shell, such that the electroformed shell is deposited on each accessible surface of each insert to secure the insert to said electroformed shell and to obtain a bare electroformed component through an electroforming process; removing the resists; and destroying said equipped sacrificial substrate.
