As much as I will most likely never spend 6 figures on a watch, I greatly appreciate their engineering. Tangential, does anyone know how easy is it to design and build your own movement?

I don't know about the difficulty, but you can look at the complexity of this ETA 6497 movement on GrabCAD [0]. After seeing this a while ago, it made sense to me why small/new brands generally use a Seiko NH35 or something similar that they can buy in bulk.

Thanks a lot! Sounds like reverse engineering a complicated (heh) watch movement could be a fun challenge to start with!
