If I'm not mistaken, it is a fairly new model. It was posted in one of Puretime threads on RG. Hopefully Angus can get the factory to move on it as it is a stunner. I'd grab one in a sec.
These pics are SIHH 2013 preview pics from IWC. Meaning this watch won't even debut until January, then available to the public sometime in late spring.....My guess is no reps till end of next year.
