There are many types of watches out there. Some have special functions built-in, some make sounds, and others toy with your mind. The TokyoFlash Optical Illusion Watch makes it a real challenge for your brain to tell the time by making you strain your eyes looking at an optical illusion on the face of the watch.
If you can’t seem to see the time, you can touch one of the four hot zones on the touchscreen to reveal it. There is a mode that will cycle through puzzles every 20 seconds so you never know what to expect when looking at the face. Obviously this is a great conversation starter, as well as a good way to remind you to check the time. It is a rather complex timepiece in comparison with the regular old digital watches, so the $180 price isn’t surprising.
