TIWE - Cool Concept OLED Watch
This concept TIWE OLED watch is the brainchild of Lv Zhongfang, a product designer based in China.
The white dots appear randomly on the surface of the watch. Shaking the watch or gently tapping its glass surface makes the white dots to align themselves to show the exact time.
You cannot buy one yet, as the designer is still waiting for a manufacturer to turn his concept into reality.
