I know the 7750 has legions of haters, but a few of us respect and actually like the cheap workhorse. I had read that IWC used to modify the 7750 to their requirements, then ETA built it to IWC specs only for IWC.
Is the IWC version of the 7750 the best 7750 version available? Are there others who use a higher-spec or better finished 7750 in their chronograph offerings? Who?
