Yeah, well... Let me put it this way: The Speedmaster Moonwatch is the only watch at this price point where I find plexiglass acceptable.
But if you want something to not have to worry about, by all means, get the Sapphire version.
I just love the way the Hesalite looks and that it's the one they use/used in space because it won't shatter into a million particles if it breaks.
For me, Moonwatch and Hesalite vs. Sapphire is like a Ferrari with a combustion engine vs. a fully electric Ferrari which surely will be faster and more modern than any V8/12 that ever existed. But it just doesn't feel right.
