$550 is a real bargain, cheapest Autavia I've seen for a long time!

I could live with the bezel whilst looking for a replacement, the only other real black mark is that the case has been polished - losing not only the sharp edges as Stewart mentions, but also the brushed finish on the upper surface. There are a couple of guys here on the forum who get very good results with case refinishing if that bothers you - I don't normally recommend it actually, but when the case is significantly polished to start with I guess it matters less.

Still, at that price, nothing to really worry about.
