..welcome to the forum. It's always nice to have new purist joining and sharing.
The 005 is my first step of Panerai journey. I love to strap my experience with the Logo, therefore my choices were down to 2...the Zero or the Five. I love to see some movement on the dial..so my ultimate choice is the 005. That was my whole story of making decision.
Both are nice. Please keep us update your move.
Cheers
