Crystal/Glass material

I am looking at a Mondaine Sport II Gents Chronograph that dealers list it as having a sapphire crystal, but the Mondaine website show it having a sapphire coated crystal. What does sapphire coated mean?

Hi KILO5 ! Not really sure about this one, but found a link to Watchuseek where they seem to
be talking about the same thing. Sounds like it "might" be a mineral crystal, which won't shatter
like a sapphire, but then uses a sapphire coating to guard against scratching of the mineral crystal.

Again, not really sure about this KILO5. Maybe someone else can help out even more.

Here is that link by the way for you...

Check this link out as well KILO. Looks like #7 might have something to do with your question...

Thanks for the info AtomicTom. It appears that it's a mineral crystal with a sapphire coating.
