KC,
The knock-offs and replicas just keep getting better and better. Newer technology is a big help to these guys who can fabricate the perfect case, bracelet, dial and the rest. The only thing left is the movement...no problem!! Good ETA movements can be had for less that 50 bucks!!
So there you go....a superb looking replica that can fool even the experts. Every tiny detail copied and forged to perfection. Combine that with a good ETA 25 jewel movement and....VOILA...you have a super-duper fake!!
Your ONLY SURE bet to avoid all this is.....go AD!!
