I bought 2 new casios(1 a g-shock) off ebay, both power sellers being in Hong Kong. This was a few months back.
In both of the little accompanying instruction booklet is written:
"This warranty certificate is valid only for service in the country of purchase."
So if I bought it from someone in HK, and I am in Australia, where is the country of purchase?
Also, would a printout of the ebay invoice be sufficient proof of purchase for the warranty?
