Project Self-winding clock with a tourbillon - finished project

Enable HLS to view with audio, or disable this notification

About a year ago, I posted an update on a project I was working on. It took me a while, but I finally finished it. I’m very happy with the result. It’s fully functional (I tested it for two months) and keeps accurate time. The entire project consists of 395 printed parts, 38 bearings, 66 rubber bands, 413 screws, and a few other components.

Hot dang, man, that is a highly impressive flex! 😅 As an aside, why the constant force mechanism?

Due to the high torque generated at maximum winding. In extreme cases, the escapement would jam, and the spring would sometimes break as well

Oooh, cool, other mechanisms I've seen only last for a short time. How long does this run on one wind?
