Thats true..
Many sellers on ebay are selling Copy Casio Edifice...
They say it as Imported, that means imported from China or Hongkong...
After buying the watch you can just walk into the Casio service center and just ask them to check if this watch is original or not..
Dont mention the price of the watch at service center and just ask them to check it for its authenticity...
These copies are exactly same as that of the original but the inside machine or some sensors differ..
We also sell Casio edifice watches, but they are all Authentic...
I guess there is no solution to these problem as you cant recognize its authenticity by its physical looks or any kind of logos( all are point to point exactly same )
