So I stopped in a Rolex AD again today, and low and behold they actually had a black/SS sub in stock. So I spent some time playing with it. Wow, that thing just does NOT feel like a $4500 watch. Fine with me, though, because now I'm not the least bit tempted to shell out that kind of cash. All the while I'm inspecting this lightweight watch, the guy is staring at my 7753 196 old case too... Finally he says, the sub is going to feel flimsy compared to your "Pan er ray". To which I said "Yea, 'pan er eyes' are real anchors!". He then commented about how the top three popular watch makers right now in terms of resale were Panerai, Rolex, and Patek. So, as it turns out, he was probably one of the more informed AD sales droids I've encountered.
