'How Apple Makes the Watch'

Greg Koenig, writing at Atomic Delights:

This walkthrough is a detailed narration of what we see in Apple's Watch Craftsmanship videos. Of course, we only get to see a mere fraction of the process; I've tried to provide plausible explanations for the likely steps taking place between the processes shown on film, but these are assumptions and are included only to provide a more satisfying and complete narration.

This was a terrific read; I'm fascinated by the manufacturing films Apple made for each metal.
