If you see it on a display, it looks bigger than a 44mm Panerai but when you put it on your wrist, the watch shrinks!
It "dresses" like or better than a Moon watch.
And, of course, I love this complication in special after I read an interview with Mr. Richard Habring and I learned that he was the designer of a 7750 based one, when working for IWC.
I don't know if the Omega one carries Mr. Richard Habring design but ... who knows.
Cheers,
