I know this us useless without pictures bit this is my initial quick "review"
Just picked up mine today, dial is a beaut, slight silvery hue to it when light plays on the surface.
Strap crap as per usual but not as bad as some I seen before.
Date is centred and not sunken or too deep set compared to the gen pics I have been looking at.
On to the crystal,
well, I have been tapping and comparing the pitch to my other watches and it has the right sound to it. It also feels cool to the touch longer than my plexi glass watches. Have also poked gently with a needle along the bezel rim and it does feel like the needle point will not mark it... obviously I have not applied any significant force but it has a different feel to it compared to the plexis that I own.
The tactile feel, touch, smoothness/friction etc is the only thing that makes me a bit uncertain, it feels somehow more like a plexi but that could just be up to that I don't have any other sapphire crystal watch with this dome shape. Anyway the glass is clear without imperfections.
So my verdict is that if its not Saphire crystal it is at least a plexi of very high quality possibly with a good scratch resistant coating on it.
Winding is smooth, its definitely based on an automatic and probably a Miyota 8205, finishing on the decoration is good, equal to the Aqua Terra 8500 (I have a Deep blue dial version)and the Miyota stutter is not visible on the watch I received.
