separately, i imagine not just leica, but the entire optics industry has answered the question of precision/quality at scale before?
and finally, there're more , right? like mercedes-benz, bmw, lexus, porsche, medical instruments, the aerospace industry... don't all of them have to solve 'quality at scale' problems?
and at smaller scales..parker pens? zippo lighters? swiss army knives?
and then..something like http://www.muji.us/store/ could be good enough as far as the perception of quality goes?
