Une lectrice, professionnelle charmante et prudente me demande :
"Je ne connais pas du tout et ne trouve rien sur Mecan Elde (signature). Connaîtriez-vous par hasard svp ?"
It is prohibited to manufacture works in precious metals which include one or more parts in base metal, whether they are welded, screwed or simply connected.
However, the administration has authorized the use of base metal elements essential to the proper functioning or proper use of the works provided that the said elements are not welded and retain their natural color, and provided that the works bear next to the hallmark of
manufacturer the words “METAUX DIVERS” or “M.D.”, or “MECAN” (if it is a mechanism). (Ministerial decisions of September 22, 1896 and May 15, 1916).
