Pilot Professional Chronograph - sapphire or mineral crystal?

[WiZARD7]

I've bought a used watch, its paper dates 2009.09.22, its model number is 597.22.114.
The seller said it has sapphire crystal, but I doubt it.

On the outside I'm sure it doesn't have any AR coat...
There are some, very little scratches.
It fails the "water drop test", but I can't decide about its colour. (I'm sure it is not pink, and I have an Omega with sapphire, that is not pink, the colour is greenis/blueish like the Fortis)

here are some pictures: http://wizard.beats.hu/fortis4.jpg http://wizard.beats.hu/fortis10.jpg

Based on its model number I think it should have sapphire.

Can you help me?

if it is mineral crystal, then how much would a sapphire crystal cost?
I don't know wether give it back to the seller, or try to bargain... I really like this watch, and the price was ok.

I've contacted Fortis, they said:

"Since the year 2002 the pilot professional chronograph is equipped with the normal saphire chrystal.

Normally your watch should have a saphire chrystal also.
The watches are equipped with the normal sapphire chrystal. The anti-reflective one is an additional option."

So I don't have any reason to assume it is not sapphire.

I also recall that AR coating was optional on Flieger/Pilot professional models. B-42 are standard equipped with AR coating. Older Flieger models have mostly mineral glass.
