Those itty bitty screws that hold together your watch (or possibly your smartwatch) are infinitely frustrating to grasp, position, and attach to said watch. Now imagine the precision required to make one of those screws. Seeing the process captured gives me anxiety. What if they drop it???

Watching This Machine Fabricate Tiny Screws Makes Me Nervous

All of this happens inside a machine called the SwissNano by Tornos, a fascinating little watch-fabricating unit that can produce about two-thirds of the moving parts in a standard watch. Now if you really want to feel anxious, imagine a person trying to accomplish the same task as this 10-foot-long robot. It's a miracle that we ever really knew what time it was. [Digg]
