To my surprise, when I was admiring my newly acquired SBGW231 this morning with my Loupe system, I found few water drops/ marks “trapped” in the edge of the sapphire crystal... I brought the piece to AD and they said it has to go back to factory for repairing... 
Honestly for some reason I had a very high expectation from the Japan manufacturer who supposed to be very reliable especially on their QC.
Maybe it’s just my bad luck.
Now I hope my watch comes back in perfect condition (scratches and marks-free)...
