hmm... i always thought that if a watchmaker is serious enough to put in complications like moonphase or pr display, this should be good enough to separate the product from a fashion-brand watch.
to me, a fashion watch relies strongly (or maybe even solely) on a brand name made famous from other line of products (clothings, fashion, etc). And secondly, a fashion watch emphasizes a lot on colour, size, design, bling bling, etc...
Looks like i still got lots more to learn though..
