.....yes
The 3450 is rarer and with the leap year indicator....but one of the things I love so much about the 3448 is the purity of the dial. I find the leap year indicator a distraction from one of the things I love on this genre. Hence, my love is 3448 over 3450....but it is such a personal issue.
Notwithstanding the beauty of so many PP watches, to me the 3448 is king. If i had to keep just one PP, this would be it...plausibly over any other watch i own. I think it may soon be time to discuss this one on the forum more fully!
