I did the same mistake one year ago i bought my first Panerai a rose gold 336
then got in to P.com and started following the guys and I got in to the base hype
so i sold my 336 to fund a 000 and a005 plus got on the list for a 386 (witch most likely will never arrive)
and went all the way to Israel to get a conformation that i will get a 382 ( '' '' '' '' '' '' )
all this in the first 3months of me getting to know PANERAI
THAT IS WHAT THIS FORUM DOOS TO YOU
I jump'd and i really regret selling my 336
So my advice is keep the 320 and save up for the next
by the time you're ready there might be something better then the 372
PS: whatever you do with a PAM you're in good hands
