Mineral Glass is a watch industry buzz word for heat treated glass.
Sapphire crystal, on ALL watches, regardless, of make is Synthetic. Natural sapphire is far too rare, and not large enough, or pure enough for watch crystals.
If someone tries to sell you a timepiece with "real". or Genuine" Sapphire, rather than synthetic, they are feeding you a sales gimmick of a line. Period!
