The original hardlex crystal, 4mm thick.
Now after the operation I realised, there isn't much to shout about, in fact I was quite disappointed.

Taken at K2 during the dial operation.
After pictures, taken today.
I concluded that the sapphire crystal offers very little differences over the hardlex crystal as they are both domed and the usual blue tinge from anti reflective coating isn't very obvious.
It's a nice to have mod if you just want that additional scratch protection for the crystal.
