“Sigma” dials
In the 1970s, the presence of the two Greek letters “Sigma” on either side of “SWISS” was intended to give a distinctive sign to Swiss-made dials with solid gold hour-indexes. Only members of APRIOR (Association pour la Promotion Industrielle de l’Or) were entitled to use this mark; among them, Patek Philippe, Rolex, Vacheron Constantin, IWC and Omega.
