Thanks for your contact.
IT's Casio 1 Year Limited Warranty, not Singapore Warranty though. Please refer to the attached file.
We sell only through official prime dealers.
And there is no fake, no imitation.
But sometimes the product has relabel, repackage, renewal.
and there are many package versions.
So It is possible to be different from feature each other in period of changing time .
I fully understand the meaning of your doubt.
For example, some of items we are selling item, there are 3~4 more types of label and Feature.
But all of products are same and genuine.
We sell the items although the world.
And We can't sell fake! We are not a temporary seller.
We always sell only 100% genuine items!
We are proud of this policy!
If US local dealer selling fake, We don't deny all duty.
And We make the US dealler take legal responsibility.
Again, we can guarantee about authentic item.
