I think that it really is tme to get rid of the 7750 inside. I love what IWC does with big 'tool' watches, but having owned the Doppel, it bugged me quite a lot to watch the day and date change 'forever'. It took about 90 mins as I recall, with the day and date going in different directions... anyway, maybe it's a quibble? But these are nice big well executed designs IMO, I just can't lay down the K's anymore on a 7750.
