No one sane is arguing that an expensive mechanical watch is better at telling the time than a cheap quartz watch. If you want accuracy, don't buy a rolex.
Personally, I think a fancy watch is more comparable to buying an art piece. A painting is not "superior" just because it portraits its subject with more accuracy. Similarly, a watch is not "superior" if it tells the time with more accuracy.
I wear a watch because I like the watch. I like a mechanical watch with an open back so I can look at the gears turning inside. I like the attention to detail in the design. I like how the little hour indicators are polished to a mirror finish. For me, it is a piece of jewelry, that also tells the time.
How do you plan on that happening?
