Do ADs stock rolex watches or is it just usually what they have out is what's for sale? I'm getting ready to buy a GMT Master II and I've been to this AD quite a few times to look at and try on the watch. When I asked if that was the one for sale or they had anymore in the back she said that was the only one. Is this common practice for ADs? I examined the watch and it's in pretty good condition. It still has the protective plastic on it and doesn't have any noticeable scratches, the only flaw that I see is there's a little bit of dust built up around the cyclops which shouldn't be a huge issue. What do you guys think? Would you pay retail MSRP for a display model watch?
