In spite of my above reply, these, however, may be fake:

They look like Kratt, or something that even predated Kratt. However, a few things seem off to me:
1. Diesel almost never uses a zip fly, which these supposedly have.
2. If those are the Kratt, or one of its predecessors, then they'd have the double "V" back pocket stitching, not the red "D".
3. It wasn't until later, as far as I know, that Diesel started using the top button with the "hole" in the middle, vs. a completely covered button.
4. If you look at the back of the waistband on a pair of genuine Diesels from that era, you'll see stitching about two inches on either side of the center belt loop from where the interior waistband tag was sewn in. This pair doesn't have that, while the genuine pairs below (as well as the pairs of Kulter and Fanker that Yoox has) do.
Compare them to these, which appear to be about the same age, but have the details I typically associate with Diesels of that time period:

However perhaps someone can identify them definitively as genuine based on the pic/description...
Also, compare these (look fake):

to these (look real):

These are also highly suspect (though Yoox doesn't have a nearly identical pair of genuine ones for comparison):

In addition to the characteristics mentioned above (other than the stitching for the inside tag, which is there) look at the stitching at the top corners of the back pockets. Usually it's straight across and appears very well reinforced, whereas this stitching is thinner and diagonal.
