I own the 372 and have really come to enjoy the plexi crystal, even as it has acquired hairlines (something new for me, to see marks on a watch glass). It is more appropriate for the watch, IMO.
I believe I previously commented about the PR indicator on the movement as well. I generally like it; I think it looks terrific as executed, but I do not understand it on what is otherwise a very traditional and historical looking model. I think it would be more appropriate the contemporary pieces.
