Question about a crystal on a watch

Recommended Posts

Did a quick Google search, and saw it come up on a couple PAM homages on eBay. I then did a quick search on sapphire, mineral glass and acrylic glass... and acrylic glass has the molecular formula of (C5O2H8)n... my chemistry is VERY rusty, but I think the n indicates a polymer strand, so my guess is that carbo-hydrogen polymer is an unnnecessarily fancypants name that indicates acrylic glass.
