I was in Schaffhausen last year to see the IWC factory (but it was closed). Although I wasn't able to see much more than the museum, I was able to meet with a watch repair person and see them fix a watch. In our conversation, they asked me if I was interested in buying an IWC (or if I had already purchased one) and I told them that although I loved the portuguese chronometer, the portofino was more in my price range (before they substantially increased prices).
Interesting thing was, they almost immediately disapproved. They said the portofino was a very common movement that wasn't worth my time (no pun intended I think), and that I should buy either a portuguese chrono or an ingenieur, in steel.
I'm interested in people's thoughts on this, as I still like the design of the portofino, though I don't like the idea of a subpar movement. I know IWC would never put a poorly functioning movement in a watch, but the comment from the repair person was most likely an "honest" opinion from someone very knowledgable on the subject.
