Dot-To-Dot E-Paper Concept Watch Design via Tokyo Flash
Design concept for a watch that displays time like a Dot-to-Dot puzzle (see animated GIF below)

“The idea for this watch design concept comes from dot to dot drawing. These “coded” images have their own artistic appeal and make an interesting display for a watch.The time is told by numbered dots. This might be confusing at first, because the numbers don’t tell the time directly. One quickly figures out that the dots have to be connected to show the four digits of the time display. If there is not enough time or imagination, there is a button for a quick solution. But why not solve it yourself? You can join the dots with your finger thanks to the touch sensitive e-paper display.
