At first glance I thought they looked great, but as I look closer I find more nits to pick.
I like the overall look, and the use of titanium is a plus. I have always preferred subdials at 6 to the (Power Reserve) subdial at 3 of the BP's we are accustomed to. Thus, these new ones really caught my attention. But I would sure miss watching that big honkin' center second hand sweeping the dial of the BP! I also wonder if the subdial is a bit small compared to the scale of the watch, but would have to see one in the metal before I could be sure of that.
No way I would wear a 55mm watch. Even 48mm would really be pushing the upper limit for me, and again, I would have to actually see one and wear one to know for sure.
I love the way IWC always honors its history and how the DNA is always so clearly visible. Even if there were no name on the watch, there would be no question of its origin!
So I love the concept, not quite as sure of the execution, and will very much look forward to seeing the new pieces in the metal when they arrive on this side of the pond.
