Ben 10 Alien Force Omnitrix! (Simple Version)

This was an Omnitrix I made several years ago. It doesn’t fit my wrist anymore, but it still looks cool.
I figured I should put it on my DeviantArt account, now that I have one.
This Omnitrix has a very simple design, and does not have the detail of the Alien Force Omnitrix. (Hence “Simple Version” in title)

The Omnitrix also comes with a twin: the Albedo version:

I am in the process of making a VERY detailed Omnitrix (AF) out of foam sheets and the face plate will move up and turn. It is close to be being finished, but I don’t work on it too much, so don’t expect to see if very soon.
Also, if anyone can tell me how to make a wrist strap that is fairly seamless that I don’t just slide on and off, I would be grateful; I’m really stumped on that.

I don’t own Ben 10 or Ben 10 Alien Force
