I think what hurts Breitling in the eyes of Rolex fans is the fact that one can get a Breitling at a big discount. This deep discounting has a negative effect on the brand and is perceived as a sign of lower quality. If you discount that fact (pun intended), you can see that pound for pound (or milligram for milligram) a Breitling is every bit as good as a Rollie any day of the week.
