Hi Ry, thanks for the feedback! Your crystal was actually from another coating lab that I used earlier, these PO crystals have pretty much different AR.
@Rolexman: Rep PO crystal AR is not like gen AR at all if you ask me. It makes the dial blue and that is not the case with a genuine crystal. New genuine crystals have really great AR coating, normally the crystal is just colorless. On the left a genuine crystal on my Franken UPO, on the right my PO crystal. Both have really small reflection so I cannot say sure about the reflection color, it changes easily when captured:
