Hey guys, I'm considering this Seamaster Calendar 503(?). But I have doubts about it, specifically the Omega font (doesn't look as crisp as other examples?) and the number markers looking a little wonky. Im also not sure about the lugs and case, if they've been polished. Everything seems original except for the strap, right? Seller is asking for approx USD 680. Looking forward to hearing from our members. Thanks!
