"80% harder" ≠ "invulnerable". Not sure why some people don't make this distinction. As for the "posh" british accent, if you were to actually go to britain you would probably notice a lot of people talking just like that, without necessarily being all that posh.....but the Apple Watch uses a special cold forged SS that's up to 80% harder than ordinary steel! And the person saying it even had a posh british accent!!!
