Someone I know buys fake Rolex watches from a maker who shoots detailed videos of the fake watches and emails them to potential customers. The phonies sell for about $450. I'm not a watch expert nor a watch collector, so I can't vouch for the quality of the knock-offs, but the care that goes into the videos is impressive. Anyway, here's a video in which an expert compares a $4,000 Omega Seamaster Diver 300M with an incredibly impressive knock-off costing 1/10th the price. Only when you zoom way in to see the minute details do the differences become apparent.
