Yea - I'd assumed the hour hand had some sort of dead-reckoning compensating gear on the joint in the middle of the clock similar to a south-pointing chariot[1]

Yea - I'd assumed the hour hand had some sort of dead-reckoning compensating gear on the joint in the middle of the clock similar to a south-pointing chariot[1]. I'm actually a bit disappointed they used magnets since it'd be so easy to mess up the orientation with a bit of otherwise benign interference.

That happens to a fair description of magnetic compasses as well. I suppose that’s why some compasses use a modern version of the south-pointing chariot (gyroscopes).
