Have to say the Chrono Monopulsante 1950 Luminors (311, 317, 375) really turn me on. Of course the 317 is mastepiece, but trying on the 311 made me an even bigger fan.
I consider the 311 to a very important piece for Panerai. It is not popular, but should be. It was the first PAM to offer a powerful mix of old and new, providing alot of cues to where Panerai was set to go, as of 2008, when it was first announced. In-house, (P-3000) 8 day manual, with GMT and single push chrono housed in the perfect, understated titanium 44mm 1950 case, with brown sandwich dial, and domed crystal - all make for a genuine classic in my book.
The 311 speaks volumes to me as a seminal piece, than when I tried it on at the NY boutique really helped explain an important chapter in the horological growth of Panerai. I felt as if I was wearing a piece of Panerai history that has not been recorded yet, except perhaps now.
So yes, the 311 (of course 317) and 352 (to me the best Panerai on bracelet ever produced) are what I'd like right now.
