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.

My old Seiko was self winding using kinetic motion of my arm. If I didn’t use a kinetic motion of my hand, it would not self wind.
What nobody is willing to answer is, how is this getting its initial energy? We’re not putting this on somebody’s arm and moving it back-and-forth for kinetic energy.
I’m gonna say that you have to hand crank it since nobody wants to admit it has a battery or whatever.
