Deep down, I prefer 21 and 203 over 217 and 232, other vintage models are even better, but I don't feel right in paying exorbitant price for many in the Pam family. They are very very pretty in design but lack the technical substance to demand such high prices imho. Don't listen to me, I'm just a poor man lusting after fabulous watches.
Great design + simplicity is the very thing that makes Panerai so attractive.
