The most scratch resistant crystal available
The vast majority of watches in this price range will have a mineral crystal (the crystal is the glass situated above the dial). Although it looks fine, it is easily scratched, ruining your watch (it’s 6 out of 10 on the MOHs scale of hardness). The crystal on your Regnum, however, is sapphire – a whopping 9 on the scale. Sapphire crystal is used by all the top brands as it’s the best and most resistant material for crystals. Diamond is rated at 10 – so you get an idea of just how hard sapphire is. Feel secure knowing that you have the best crystal going.
