I love these! I’ve seen them referred to as “hand in hand” clocks and there are a handful of physical manifestations that you can 3d print or make yourself

Cool! I didn't like that the orientation of the clock hands rotated over time, and I made[1] one that maintains the typical analog clock hour/minute hands alignment with 12 o'clock while rotating once per minute on a long second hand.

Scroll down if you don't want to wait for it to finish. Squint, and you might see a 12-ness nested in the epicycles.
