I think it cannot be stressed enough how important the source for your rep is. I mean feel-wise, quality reps from quality dealers are generally almost spot on, but it's always the little details that separate them from the gen, e.g. hour markers, lume quality, dial print etc.. Honest dealers disclose these details without hesitation.
Quite honestly, only rep collectors like the lads here would know these inaccuracies anyway. The average guy on the street would simply say "nice watch"..
