The Robert (that's my watch in the video).
The movements are the same. There are quite a few people slapping their own dials on these things.

I hope it's ok to link to another forum, but I've just noticed there's a very timely thread developing over on watchuseek on exactly this subject.

I've got one based on this. It keeps very good time - I probably don't wear it for more than two or three days at a time, and over that sort of period, it's accurate to within just a few seconds.
I would however expect the accuracy to be very variable across different watches.
Here's a YouTube video of the tourbillon:
