Sapphire Crystal Detector?

Guys,

I was in a watch store in Turkey browsing his wears (very gingerly because of all the fakes) and he brought out an electronic device to prove the displays on his watches were sapphire crystal.

I've never seen one before, it was a small handheld device with a metal tip you pressed against the glass with an LED scale showing what I think was the hardness of what it was pressed against.

My Rolex and wife's Tag Heuer were off the scale, as was my wife's engagement ring! :-) He showed me some that weren't sapphire which showed clearly on his tool.

Does anyone know what this tool is called and where I can get one??

Thanks,

Chris

PS I was BLOWN AWAY by some of the Swiss made "replicas" they were selling. It was actually frightening how good the copies were and would have struggled to tell the difference - BE CAREFUL OUT THERE PEOPLE!!

It's the same device used to check authenticity of diamonds.

No need to buy anything.

Everyone has a built in tester, it's called forehead.

Touch the crystal to your forehead and if it's cold to the touch it's sapphire.

Not a joke, try it and you'll feel the difference immediately.

Forgot to mention, it doesn't matter if you're indoors or outside, still the same result.

Try it and report back.

Not really a discussion of Rolex. We're getting close to a discussion of fakes here.....
