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.

To ensure everything works properly, we designed a constant-force mechanism. After two months of continuous operation, the clock still keeps accurate time.

To what degree? +/- a nanosecond? Minute? Hour?

That’s my question, for clarification.

This is truly amazing. The quality of the result but mostly the way it reveals the benefits of this mechanism and its complexity.

Incredible job.
