I have seen quite a few 168.004 popped up recently including one that has the same dial features shown above: sunburst silver cross hair in good condition, onyx inserts, marker beside date window. All desirable features except for the rounded pipe pan, IMO. Unfortunately most of the cases are soft: facets on lugs and near bezel are pretty much gone. From my observations, EBay prices tend to flirt near 1k usd to 1k euros depending on condition.
