I'm starting to walk down that path myself...
I'd say top right one. Classic Panerai, w/ a modern sprinkling of a subdial at 9.
Or if you want one that the non-Paneristi can appreciate, middle right.
I don't know the model #s are since I'm a Panerai-noob. I think the second one I recommended is a 023. I only know that one because I just got a 089 and 063, so I happened to look at the other GMTs. I really like the classic looking ones, but I ended up with the 063 because it's still classic looking, but is a little more decorated. My gf thinks it's nice looking, and I think girls are really good judges of appearances. They have no biases, they don't care where the watch is from or its history, or how fast the car is, or anything like that. They just say, "Hey, that looks cute" or "Ugh, that's ugly."
