I've always found a diving watch w/ rotatable bezel to be the perfect watch that represents Panerai, a brand with such a strong association w/ military divers...

Then it came the Bronzo! Believe or not, I actually turned it down initially when I was offered one, as I didn't like the idea of gold coloured watch in Panerai, from my days of PAM289. But boy I was so wrong, when I started to see pictures from fellow owners on their wonderfully aged case...
