The link below has a 756 diapal which I've negotiated a deal and have two days to accept. Should I? Anyone see any red flags? The seller appears established as a good watch vendor; he's outside the US but that's common with Sinn. The box and papers are not included which is a strike.
Photos look good to me, but I'm no expert.
Good find or beware?
