A couple of weeks ago I was looking through a glossy advertising supplement a that featured only ads for high-end wristwatches. Most of the these expensive timepieces were of the classic mechanical variety. The photos had big, extreme close-ups of the watch guts – gears and springs, etc. I honestly could not believe the complexity of these machines. And the parts! They looked so delicate it seemed like a sneeze would bend them. But these parts were not just random pieces of shiny artistic jewelry. No, they had to work, and work perfectly.
How do they make such small delicate parts? It looked like the parts could barely even be touched without bending or breaking.
