That is a straight up gorgeous piece of film making and advertising.
The sights of the aluminum being forged, poured, machined, anodized, and finished are absolutely stunning. Go watch it again before you start looking at the science of what's happening.
We get the full gamut of processing (forging, machining) and materials (metals, alloys, ceramic - zirconia - beads for the finish).
And that doesn't even being to touch on the gold and steel videos that I'm putting after the jump.
All of these are available on Apple's watch craftsmanship webpage along with text and photos of the zirconia chosen for the crystal covers, the ion-x glass for the Sport face (potassium ion soaked to increase strength), or the sapphire facing for the Watch and Watch Edition editions (that sounds incredibly stupid to read).
There is also a webpage from Atomic Delights (a blog with sadly only three posts in two years - better quality than quantity, I guess) that does a far better job breaking down the three videos and speculating on some of the science therein than I ever could.
