I've been really excited to get my first vintage Omega Seamaster, but now as I am able to take a much closer look, it very clearly appears to be a re-dial. That's not necessarily a deal breaker, but I really want to ensure this is the real deal. Couple of observations--no "Swiss Made" at the bottom and the OMEGA appears to have been re-done when zooming in. These are the sellers pictures--I haven't had a chance to open her up. Purchased for about $400. Thoughts?
