Hi heuerboys
have just the same constellation autavia at home:
steel hands,MH bezel,cal.11 movement,1163 signed case without V(2239XX) and viceroy dial(1-12 on left subdial)
Seller was a swiss collector who told me that he has bought it new in the seventies and was never touched then,...and if a trustful swissman tells me I will trust him.

Once they worked up the last parts they could find and threw it on the market as complete watches,I think.
Yours had a hard life on the track as the pics show.
cheerio tom
