I have a number of watches and my Panny 233 doesn't get lots of wrist time, but the basic Panny is classic and changing straps is like getting a new watch.
Much is made of in-house movements. Nothing automatically better about them, but I'd stick with the p2004 movements or one of the modifications of it if it means a lot to you.
Finally just a comment about the JLC movements in the AP ROOs cited earlier. You'd be hard pressed to buy a new one without the in-house movement (3126/3840) as they made a transition a few years back starting with limited editions. This Montawk Highway LE I picked up last summer certainly has it. I think even the basic rubber clad models have it now too.
