How can the Japanese keep doing this to us????? They always come out with the most ingenious and impractical watches to own. I do admit yes it would be awesome to show this off at a party or at school but it is a real strain on the eyes to keep looking at. It is indeed intriguing that they found a way to relay the time to people via optical illusion and all but I seriously think that this will take up too much time to even bother with. For those of you however looking for a watch to boggle the mind, impress your friends, and be the center of the party go check out the optical illusion watch.
