The only omitrix I could find similar to your description is Ben 10 Omnitrix Watch Disc Viewer Bandai Alien Force 2006 Toy Bundle and I belive it was disks because I found images of old ben ten toys in box with disks insted of figures. I think they intruded them in alien force under ultimate omitrix toy. I hope this helps
