WARNING: Sapphire Screen Scratches!

Just a warning to those Apple Watch users that have the sapphire display and expect it to be as unscratchable as typical sapphire watch displays: It's not.

While showing a friend that the sapphire display doesn't scratch today, I took my pocket knife out of my pocket and used the blunt end of the nub that's used to flip the blade out and scraped it across the screen a little bit. Later in the day, I noticed scratches. I've tried everything to remove them, but they're permanent.

This means one of three things are possible:

1) There is a coating on the screens that even goo-gone can't remove (I tried, it didn't help. Scratches remain).

2) The knife that I used has a high-enough carbon rating that it ranks on diamond level and was able to actually scratch the screen. Unlikely since doing the same thing to a citizen watch I own with a sapphire display did not scratch it.

3) I received a Stainless Steel watch that accidentally was given a regular ion-x display.

Or, 4) These displays, while sapphire, aren't as pure as typical sapphire and scratched from something less hard than diamond?

At any rate, I am NOT pleased as you can imagine. Wanted people to know before they tried and scratched their watches too.
