Now that you mention it, it was partly the dial. Primarily though, the bezel didn't look right. Too thin? Maybe I am too attached to the original version. The polished center links are another minor thing.The PO is pretty thick.
@Sweden. Good call. I totally agree with BH. I've seen head only pieces list close to 3k USD without B&P. I'm not stuck on papers for older models particularly but the bracelet is pretty important.
Edit: it also depends which serial. As Dino has mentioned previously, SEL bracelets are preferable and they do sell for a bit more.
Under 2k sports watch is where I am looking right now for my next watch. If used is ok, I would look at Longines, Omega and Tudor although they might push your limit slightly over. Several German brands including SInn, Stowa and Junghans can also be found new under 2k.
