If the caseback was from 1960's it would say "waterproof", not "water resistant". Case looks period to me, probably just a new back. Gorgeous dial and hands look 50's though. Frankie, is my thought, though a very handsome one I would enjoy wearing, Peter. Very nice.

I may have the answer to the strange case back. My back has the little tang sticking out on it too but it is just about gone and it doesn't allow me to tighten down the back because it slips around and this can wrinkle up the gasket. I thought about buying another watch and trading out the backs but changed my mind and am having a friend with a special welding rig fix it for me when I am ready for him. This could be a quicky fix for that reason and they just didn't get the correct back. IMO
