This is the 3d model of omnitrix of the ben 10 cartoon series. OMNITRIX- the Omnitrix, is one of Azmuth's creations and its successor is the Ultimatrix.
The Omnitrix was first mentioned by Azmuth in Map of Infinity. He was planning on giving it to Ben, but it was not complete, and Ben's maturity needed to increase before he would be allowed to use it.
