Japanese wristwatch companies try to come up with the weirdest ways to display time. Now Active Reactor offers a wristwatch called Radio Active that displays time in a radiation warning sign.

Like other Japanese wristwatches we reported about reading the time display is not obvious. The time is read by adding the lights. This new crazy Japanese wristwatch measures 3x4cmx1.1cm.
Tokyoflash sells the Active Reactor for $112.67.
