Here is a Superman digital flashing wristwatch released by Accutime. To view the time, all you have to do is open its lid. When you press the center of the ‘S’ symbol, LEDs light up around the diameter of its face in a counter-clockwise-like rotation.
There are other wristwatches from this company featuring other franchises… but to me it seems to work best with Superman since it’s somehow reminiscent of Jimmy Olsen‘s Signal Watch.
Although the main artwork on the packaging is of the standard classic Superman, the actual watch features the New 52 design.
