An interesting discrepancy came up in a fake busters thread attempting to authenticate a watch.
The image on the left comes from the Omega website, though there is some question whether it is a photo or a CAD rendering. On the right is a photo of the watch in question.
Of particular interest are the lugs, namely how they differ so much in length despite the bezel being almost exactly the same size in both images.
Are there optical distortions or image processing that would explain the differences? Could these be photos of the same watch?
