In this watch crystal scratch test video, I work out which watch crystal is best for scratch resistance by using a Mohs hardness rating testing kit. Here I test acrylic vs mineral vs sapphire vs Flame Fusion crystal vs Krysterna vs K1 crystal vs Hardlex vs sapphire-coated mineral crystal, to see if any can supplant sapphire as the king of watch glass.
