I found this interesting video online and just wanted to get your take on it.
My guess is that it is fake, but it looks rather convincing at a first glance, although the video is only a minute long...
A Neat watch.... Rather easy to replicate and experiment. Let me know your findings.
Good luck.

Its fake but interesting. The magnets have nothing do with anything besides acting as weights.
What is driving the movement is the yarn/string. The way they make string is that they twist other string around more string; apply a weight to to it and suspend it and it will rotate til it un-ravels it self.
Here's a video on the same idea http://youtu.be/3ipomq72X5g
