Happy Days... Incoming 5712!
As some of you would know, I was contemplating getting a 5712 vs a 5167 vs a 5164. I then decided on getting a 5712 and 5167 only to find none were available in Singapore. Thanks to a TRF member (nakedtoes) I was able to get one - double sealed from an AD! People always say, photos don't do this watch justice... Now I know what they mean.

Thoughts on the PAM661
I have an opportunity to purchase a new PAM661, a watch that I think is very striking. I've never owned a Panerai before (I own Rolex and Omega watches), so I was hoping to get some more educated opinions about the watch. Thanks in advance!

Subc Date for 16600
Do you think it's a bad trade to go from 16610ln to a vintage 16600 or do you think once you've had the more modern refinements you can't go back?
