The vintage had a no.11 and the new had no.32 on the clasp.The clasp on the vintage locks better and is more secure but is smaller in size than the new.The vintage used screw pins for the links.The new use pins you push out with the right tool.I think the vintage one was made a whole lot better.I am thinking of taking it down the the jeweler I had fix the clasp in my Eterna Kontiki Super and see if he can get some of the heavy nicks and re-brush the clasp.Tried the green pad but the nicks are deep.I also think the Omega logo is better looking on the vintage one.I am thinking of using the vintage bracelet.
