i have no issue with buying from that excellent auction site you mentioned, in fact 95% or more of my watches have come from there and i buy a lot of normal household things as well. a brilliant site as long as you do your research and are careful.
i'm on the lookout for a dual dial/timezone watch. so far the Oris has the nicest look with the Glycine double 24 being a close second, but this would also look nice on the wrist. its a shame you've bought the only one available worldwide
