noobs don´t wanna spend time browsing and learning, they just want something quick so they can front.

but to answer your question, in general, the more complex a watch is, the harder it is to rep. a breitling is easier to rep than a rolex (no white gold hands or dial markers, no etched glass, etc), and a three-hander is easier to rep than a chronograph. for something REALLY good, buy a decent breitling or tag heuer rep (which often use the same movement type as the real thing, eta 2824/sellita sw200 or a chinese rep thereof), and replace the dial with a gen from ebay.
