I own both, the 3717 and the Inge.
I now ordered a BP, because I love Pilot watches.
If I have to choose between the IWC out of the box, I'll choose the 3717.
All the IWC I have, I bought from Andrew, and the 3717 is awesome.
But If I have to choose only one rep, I wold choose a DSN PAM, I own 2 (005 and one PVD).
I'm still waiting my BP, GMTIIC and the Chopard XTL.
I think that the GMT is pretty nice.
I love my Tudor Hydronaut (I own a gen) and despite the fact the dial is a little blurred in the Tudor inscription, it is to notch. And love my Patek Nautilus, and my Breitling SA.
Thats it.
