1. A method for assembling at least a first element and a second element to form, once assembled, an external watch component for a portable device, comprising the steps of:
a) making the first element including a top side, a bottom side, and an edge extending between the top side and the bottom side, the first element being made of a first material;
b) making the second element including a top side, a bottom side, and an edge extending between the top side and the bottom side, the second element being made of a second material that is different than the first material;
c) arranging at least a first groove in the first element and at least a second groove in the second element;
d) placing and holding the first and second element end-to-end with at least a third connecting element which is inserted and locked in the first and second grooves such that the edge of the first element directly contacts the edge of the second element, the third element being an at least partially amorphous metallic material or a material resulting from electroforming.
