Considering purchasing a Panerai while I'm here in the Caymans...few questions

[kyledrum2002]

I'm on a trip in the Caymans and I'm considering picking up a Panerai. I haven't really ever researched the brand that much other than admiring wrist shots of others wearing them on this sight. Here are a few questions:
1. I have a 6.5" wrist. What models work best for a smaller wrist?
2. As a Rolex owner, I understand the way business is done with Rolex discounts on different models. Is Panerai similar?
3. What is the best bang for your buck in the Panerai lineup?

Thanks,
