How do I tell if my crystal has AR coating?

I have an IWC Mark XV that I purchased from Trusty and I have no idea if it has any AR coating on it.

I would like to get in on Chieftang's next AR run.

I'm not familiar with that watch. But if it has a black dial, then AR is very easy to notice. At certain angles, when you catch some light in the crystal, you will just see a bluish tint. On white dial watches, the AR color (not the lack of reflections) is harder to notice. Try reflecting some flourescent light off your cystal if it has a white dial, and look at the color of the reflection. It'll be more subtle, but you should see a slight blue in the reflection.

It may also look purple-ish
