Faceless clock makes you think twice about how it works
Neat. I had figured the hour hand had a tiny gearing mechanism in the connection between the two hands. A magnet is a much simpler solution.An old acquaintance of mine designed and sold an awesome wristwatch that used two ballbearings attached by magnets. [1] Not only was it useful for blind people (it was a much better mechanism than the old watches with an openable face, which could get misaligned by touching) but it was also fun to play with, as you could spin the ball bearings around and they could get caught again by the magnet. The video of the person spinning the hour hand reminded me of that.1. https://www.eone-time.com/
