It would not figure in the fine models class but the one that made me think long and hard was shown at I think Olimpia in the 90s ! It was an anniversary of the BHI I seem to think.

It was a clock that as the day went on showed the right time, I came back several times to check, but it only had 2 hands on a plain spindle. There was no visible mechanism to move the hands or keep them in step. I have my own ideas as to how it might have been done BUT does anyone remember this item or know how it worked ? Noel

I remember that and I think there are pictures on the internet and some for sale. Possibly also plans for sale.

Two methods used. One is by balance using a watch mechanism in the hand and one using hands painted on a clear plastic disc that is rotated by a mechanism in the encircling frame.

Nice example of the latter form here

Robert-Houdin Triple Mystery Clock – Jacques Nève (horloger.net)

And a typical example of the former.

Not exactly a clock, but this video of Adam Savage looking at a fake Perpetual Motion machine at the Royal Society is interesting.

No I don't know how it works!
