There's a good chance you've recognized something 'clockish' about this trick, and you're correct. This is however a very original variation and Astor is a brilliant thinker, so it's a good one. He teaches an original deck stack that makes the trick almost completely self-working. The wheel prop is neat idea, interesting in appearance which is always good, and comes with a nice plastic sleeve to keep and transport it in. Provide your own deck. His accent is strong and some parts I had to listen hard to understand. It helped that I knew the 'clock' principle so if you're interested in this, maybe do an online research of the principle first, which will make understanding the dvd easier. 5-stars for Astor originality of a classic principle.
