If you too don’t agree with Kopernikus, Swiss designer Matthias Pugin has devised a unique wristwatch named “Dawn” that instead of the sun places the wearer at the center of the universe. But unlike traditional watches, the Dawn works with an OLED display and displays time with the pictograms of the sun and the moon, which revolves around your wrist. As it takes some time to learn how to exactly read the time, the watch also displays time in the traditional way. As soon as you are able to tell the time just by looking at the position of the sun or the moon, you can switch from showing the time to showing the date.
