Watches are the classic counterfeit -- and they are also among the trickiest for even connoisseurs to spot.
Lesser materials and cheap inner workings used to be obvious in a watch that feels lighter and doesn't work as well as the real thing, but "modern technology allows counterfeiters to reproduce watches at a level of detail that's frightening," noted Michael Friedman, watch expert and horological director of Antiquorum auction house.
One of the best ways to make sure a timepiece is legitimate is to examine the box and certificate to see if the serial numbers on the accompanying material match up, Friedman advised.
For the Super Bowl, federal agents prepped for the largest sporting-goods related counterfeit bust ever.
