This Seamaster 15700 ends tonight. The dial is one I haven't seen very often, and looks original to me. There was one posted here a while back but a quick search didn't turn it up. Has an Omega signed flex strap as well. The seller is in India, but not one of the usual suspects. I don't know enough about these to take a punt, but someone else might want to give it a closer look. http://www.ebay.com/itm/Vintage-Omega-Seamaster-Automatic-Cal-552-1960s-/191479765991?
