Have it, love it.
Yes it's heavy but in a solid, hefty, strongly built kinda way.
Also feel panerai are born to be on leather and I like the pin buckle over deployant clasp.
Fyi, it comes (or used to) with a 24 - 22 tattooed tapered strap, maybe ask to switch to 24-24 if you want to use the oem buckle on aftermarket straps which mostly don't taper.
Mike...NYC. My collection so far is a 312 and some cool straps.
