If you plan on paying $US350 for the Apple Watch Sport, here’s some good news: it seems nearly impossible to scratch up its screen, as Lewis Hilsenteger of popular YouTube channel Unbox Therapy just discovered.

But the display didn’t budge after it was repeatedly scratched with a knife:
Or a key:
Or steel wool:
