Genuine large logo Domino's dials are different than the one pictured above. Legit large logos are still not that large; e.g. the logo should not extend into the center hole of the dial, and the sides of the logo do not sit as close to the 5:00 and 7:00 markers. Rather, the top of the logo should come just short of the hole, like this one on Dowling's site:

Some other things to note: -T SWISS MADE T-, shape/height of the coronet, shape/size of the markers.
