    How to tell sapphire crystal?

    Hi, I bought a Zodiac ZO2300 and have been reviewing threads about its specs, some say sapphire some say hardened mineral for the crystal. I have been looking at it and tapping on the glass for days wondering how to tell what the crystal is made of? The caseback makes no mention. Does anyone know how to tell without scratching the crystal?

    cheers

    I've done the water test. Not always blatantly obvious but there's a difference.

My wife already thinks I'm crazy with this watch fettish, if she seems me doing this she will really have no doubt! watches to her have no meaning, however her shoes............

    I can't see much difference with the water test..not a very obvious test.

    I believe the V-Wolf does have a sapphire crystal but I'm not 1000% sure as I have never owned it but I do plan on getting one. A friend of mine who is a watchmaker can tell the difference just by tapping on the glass and he is right 100% of the time.
