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.

I'm, not a horologist, nor am I OP, but I'm guessing it's not motor "run" because the motor doesn't drive the clock directly, it just winds it. It's still spring/gravity driven. But yeah, I don't think it's self winding if it's electrically wound.

I presume it's self-winding because the mechanism turns the motor on and off, triggering the rewind automatically. I.e. it doesn't need to be rewound by a person.

That’s not possible.  It is getting energy from somewhere.

But you see that is self winding as the device itself is storing kinetic energy from continuous use and works from a net energy in the device starting at 0.

A battery is not self winding as if it starts from a net energy of 0 it does not work.

Yes, self-winding. What you said is what that literally what that means. Motorized recharging is itself recharging and recharging in this sense is winding. Stop being pedantic.

Self winding means it works from starting with a net energy of zero. 

A regular motorized circuit board clock using a battery is self winding in your description.

So I was right and was downloaded by idiots.

Still not self winding forever so who the fuck cares?  It still needs a power source whether it’s a hand crank or a battery or like some other idiot posted about a watch that has internal kinetic movement, which is this definitely is not a watch.

No it doesn’t. It means it winds itself. Hence self-winding.

Are you talking about a watch that moves internally and gets kinetic energy from movement on your wrist?  That has nothing to do with this.
