Welcome to the club. I got my first a few months back, A 1085. I contemplated that exact Radiomir, but I had to have the iconic crown guard first.
As for straps, go to the Panerai forum, there's a long list of strap makers. But my vote is to go custom, I had Aaron Bespoke make me a blue center pearl stingrays to get the ball rolling, and am expecting a grey cordura from Clover next week. Plus some Etsy makers have some nice stuff.
