I bought my Panerai 676 Due for the exact reasons in your post. I always liked the Panerai look but not the size, even though my 7 inch wrist can support most Panerai sizes. My model is 42mm and the thinner profile easily fits under a suit jacket and shirt. My everyday office dress.
The Due line brought new customers into Panerai, including me. You will not be disappointed. You will hear from the hard core Panerai fans that complain about its depth rating, lack of heritage, etc. To me, this is not important. Its a beautiful watch that I enjoy wearing in my rotation and have no plans to sell it anytime soon.
