The reason I mentioned that its the cocktail watch is that while most of the full sized mens sized watches have very similar movements, nearly all of which are capable of chronometer performance, due to the small size of the Cal 650 everything is very compact and miniaturised and these watches were never chronometers. 4-5 minutes still sounds like a lot, but these watches were designed for beauty and elegance rather than absolute accuracy.
