Hi Detlef,
So it is obviously too long (and heavy) to be a Fob Watch chain. If, as has been suggested, that it is some kind of necklace, why the necessity for the "revolving key"? It does not seem logical to me for the need of this even if something heavy was to be hung on it. I could be quite wrong here but that is just my thoughts.
