I got my space gray stainless watch a few weeks ago and love it. To my astonishments I saw something under the left corner of the screen and did not feel any scratches. I made an appointment at the Apple store and they looked at it under their scope and determines that a hair somehow crept up under the Sapphire display. Not sure how this is possible but they said they would remove it and return my watch in 7 days. I don't even have that much arm hair lol. Thought it was worth sharing.
