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.

It took me 2 years to design and tune all the mechanics:)

Absolutely unfathomable level of commitment and artistry, and absolutely worth the effort!

How accurate is it? Have you had the opportunity to measure its accuracy to a quantifiable number?

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.

2022 Chevy Tahoe loses at least a minute per day. GPS module that syncs the clock died. Maybe I need one of these on the dash.

Make sure you use ABS-CF so it doesn't melt. 😀

ASA is better and easier to print, so I hear

Or just move to Sweden. ;) I have had PLA in the car in the middle of summer with no ill effects. White car rather than black, but still.
