Another watch, I know, but the dudes at TokyoFlash Japan just impress me that much. This time (please, please, please excuse the pun) the idea behind the watch is not so focussed on the optical illusion, but rather the “night vision” element of the watch face.
The hour is told by the ring running around the outside of the face, and the minutes are read from the digital numbers displayed inside it. Looks pretty confusing at first, but once you’ve seen how it works you can see how it makes telling the time, even in the dark, extremely easy and straightforward.
