The watch has tiny white dots that rotate around the face, which was inspired by the painting Starry Night by Vincent Van Gogh. When you shake it or give the watch a slight tap, the dots come together to tell you the time. I think this would be such a cool watch to have. It reminds me of something Philippe Starck might make for Fossil.
Hopefully someone picks up this awesome concept and makes it a reality.
