I searched around & contacted a lot of sellers to find a pair of these that actually move. There are several of these out there that while cheaper, do not have the dial movement.

I bought these from  The Purple Armadillo.  They were quick to respond to emails & fast ship.

There are many on Amazon that will move only if you push the dials and then stop. On this one, if you move the cuff links or wind them up, the dials will stay in motion for a while.

My hubby was thrilled with these and everyone in his IT office were in love with them.  They were called the ultimate in "techno geek" attire.

Yes, they are a bit more pricy than some of the others out there, but you will get the quality from these.
