I bought a fake Rolex watch (Oyster Perpectual Explorer) 20+ years ago while travelling through HK. It cost me A$15.00 at the time. I hardly wear it these days but it still works well and hasn't lost any precision - no battery needed too :). I would be just as happy if it were a real Rolex.
Have you bought any fake watch that is almost as good as the real thing for a fraction of the price?
