You paranoid conspiracy fans with your "OMG it's been photoshopped!" comments do crack me up. And I mean that in the nicest possible way. If it is photoshopped, he did a fabulous job changing the reflections, tone and color of the copied "9".
Me, I wonder if I would have noticed it when trying on the watch (probably) and would have still bought it (unlikely). However, if I had noticed it later as did the OP, despite my incredibly OCD nature, I think I might be inclined to keep it because of the uniqueness. And really, I think I can figure out what time it is without the big numbers. My Speedy Sammich for instance, only has indices and I have no trouble telling that I'm late for work.
