Help identifying Datejust (fake?)

[Porollo]

Hi

I found a local listing on a datejust said to be a 2002 model. My experience an knowledge about the Datejust line is very poor. Can someone please help me out. Here are some pictures from the listing.











Does anybody know the ref number on this particular model? Can it be a fake? Does the boxes look too old to be a 2002 model?

Thanks
