Funny how those who appreciate Omega also appreciate IWC. I like Cals 83, 88, 89 a lot, and the excellent cases some of them came in - and if I had just acquired your beautiful watch (love the pics, thanks!), I wouldn't even care about whether I could trade the buckle. Sorry I can't answer your question properly, but I do hope your lovely IWC is soon wearing something "appropriate". Main headline - nice watch, well done!
