Good morning Gentleman, I am considering two Pie pan Constellations that are presently on sale locally, and I would like some advice regarding the dials. I do not know much about Omega, and although the new watches do not interest me, I find vintage Constellations very appealing. I think they are both Cal. 505 (number on movement). The white version is double marked with a jewelers name, and the black version is missing the medallion on the back. Hard to tell from pictures but I presume that both have been polished. Here are the pictures, seller pictures so as always not so good. 9 hours left to the sale and I presume that prices will go up with this post! Thanks for you help.
