I got to play with the 3448 too. Actually I am disappointed that I did not like it more. I love this design for the perpetuals. Extremely clean. however 1 think bugs me..... the case.
The case is very angular with lots of flat surfaces. PP makes many nice curvy case which is my preference generally (of course the perpetual I have is a 5059 and I love it even though it has straight rectangular lugs! Go figures
) The case sort of distracted me from the simple clean dial. It reminded me a little of the straight edges of Lange and Glashutte
MY CONCLUSION FOR MYSELF! Get the older 1526 or 2438 (but of course I am just dreaming!!) ..... and I am sure a newer version of this layout will come out soon and I will be the first in the queue!
