The problem was that I did not know they have produced 448. If I knew I would take that one. My long time authorized dealer called me and offered 425 and said they had 424 and showed me pictures. I gave it a thought and made my decision, found dealer in Cologne and I was there next day wearing my 424. After getting back home I decided to buy a "family", so I did. I don't regret. What really amazed me is 372, I never saw such a shinning steel case by Panerai. Nice one too, but now I am after 448.
