Thank you so much for the help guys!
It is hard for me right now to see a lot difference in them. I really like the sandwich dial with the second hand at the 9 position. I think I would get one with a strap. I like the idea of changing the look easily with different straps.
BTW I am going to Minneapolis in a few days. Anyone know of a Panerai dealer in that area? It would give me a good chance to check them out again closer. I need to find a good watch dealer while I am there. The dealer that I bought my Omega from is in the Mall of America. They are only Rolex and Omega though.
