It doesn't mean the buyer is stupid, it means the buyer wants an AT and is prepared to pay for it. Of course there are some people on forums who think that anyone who buys an expensive watch is an idiot especially when they could buy a Seiko
It works the same way with most luxury products be they clothes, cars, etc
Some people even pay for a logo on a polo shirt, not my choice personally, but it doesn't make them stupid.
A friend of mine has just bought a Breitling Heritage chrono, a decent watch, he spent 18 months making the decision over which time the watch in all likelihood increased in price significantly, does that make him stupid? No, he took his time, considered many options and bought his watch. A watch which incidentally he is over the moon with, this is what buying a Swiss watch is about. Too many of the forum dwelling watch cognoscenti look down their noses at people and their reasons for buying a watch, live and let live and don't be so judgemental.
