Its central stem is an air pressurized tube with three openings at different distances from the clock face and that rotate about the stem at different speeds.
Opposite each opening is a windsock. The opening that rotates fastest, blows into a long, thin windsock, the second hand. The opening that
rotates slowest, blows into a short, thick windsock, the hour hand.
The clock face is concave along its perimeter to direct the flow of air away from the ceiling/wall.

Brilliant - I'd never seen this before, but bonus points to [moom] for the realisation. |
