Wired: Here’s what you need to know about ceramic, the fancy material in Apple’s fanciest watch

God I hate these headlines. But. This is a solid article and ceramic is an interesting new direction for Apple. Lots to learn here:

“Ceramics are much more durable than metals,” says Julia Greer, a materials scientist at Caltech. To understand what she means, consider your MacBook. That anodized aluminum casing provides a handsome sheen, but drop it and you run a good chance of denting a corner. Stick it in your bag unprotected, and your keys almost certainly will scratch it.

And:

The back of each Watch uses zirconia ceramic where the magnetic charger attaches. Ceramics are non-conductive, and don’t interfere with wireless charging.

And:

Ceramics, on the other hand, are virtually scratch-proof. “They deform in an elastic way,” Greer says. “You’ll never see the deformation, until they crack.” Unlike an aluminum or a stainless steel case, a ceramic one can take a licking and keep on ticking. The rub with ceramics is that, while they’re tough to scratch, they’re more prone to cracking compared to metal.

Want the new gorgeous? It’ll cost you. The ceramic Apple Watch is the new high end, selling for $1,249 for the 38mm case and $1,299 for the 42mm case.
