You do have a valid point with regards to the 7750b movement. I have yet to buy one because the long-term stability of this movement is not yet known. I've heard both positive and (some) negative reports about it.
I have a big wrist, so 44mm & 47mm fit well. I have yet to try a 49mm or larger, but would be curious to see how they look/feel. My initial reaction though is that they'd be too uncomfortable.
Anyone watch the show Studio 60 on the Sunset Strip which airs Monday's on NBC? If so, I'm almost positive that D.L. Hughley's character was sporting an IWC Big Pilot in last night's episode.
