I made a simple backplate with a two-color gradient and added some perspective lines.
For this interpretation of the KeyShot watch I applied the blue x-ray material to the body.
Then, some heavy scratch texture to the internal parts.
Lots of post using curves and half-tones.

Just a bit to grungy for my taste, the actual watch render is a bit lost in the effect. On the plus side, it's a unique entry I think!
Cheers!
