This is true to scale just like Ben’s alien watch on "Ben 10" that crash landed on Earth in a meteorite. The Omnitrix F/X allows kids to wear it on their wrists and reenact all the action that they see on the series. It features red and green flashing lights and transformation sound effects taken directly from the show. Images of each of the 10 aliens that Ben can initially transform into are also featured on the face of the watch. But be careful, it just may transform kids into those funny alien creatures!
