And it is another move away from watchmaking. What if it doesn't catch on? Let's say they make a thousand, when they need repair these will not be repairable.
Or if it is successful and lasts 50 years, what about repairing it in 150 years time?
You can cut shape and profile metal, you can't do this with silicon.
I really dislike silicon in watches.

Yes but every maker will have a different one, and when parts run out you won't be able to get a one off made.
Steel and brass however you can.

dom_, very good points.
If parts supplies shrink sufficiently for conventional movements, we arguably can
resort to fabricating parts (hairspings, staffs, arbors, wheels, etc). The problem is that if repairs require significant fabrication...even if we have the tooling and expertise...the customer-base will likely shrink to the very few who will be willing and able to compensate for the additional time and effort.

I would love to have the capacity to do this: Masters of Time: The World of Swiss Complicated Watches - YouTube , but the market may already be saturated with suppliers.
