It’s a sapphire crystal the salesperson regurgitates dryly… rote info learned at training session. What does that mean? Oh, it’s hard and can’t be scratched! Hard as what? Nails? Diamond tipped saws? Chinese arithmetic? What? Many of you know the skinny on watch crystals, but for those who don’t! Check it out… sapphire good, everything else not so good(period). Sapphire is corundum, it takes second seat only to diamond on the Moh’s hardness scale. The last time you saw this scale was eighth grade science lab and now you are asked to remember it! Nah! forget it! Take it from CTWG, just stick with sapphire and you will be A-Ok. Watches used to be manufactured with mineral crystal (cheap models still are) which ranks 5th on the Moh’s scale, basically hardened glass. Some coat the mineral crystal with a sapphire layer, still no good. Real crystals are grown in very large synthetic tubes and cut to order for watch companies, it should feel cool to the touch and last for years without a blemish. CTWG
