It’s time to learn a little Moh about sapphire glass. If you’re not a science geek, you may not have caught that pun, so let us break it down for you. 🤦🏼‍♂️ The hardness of a material is measure in Mohs on a scale of 1-10, with a diamond achieving a 10 making it the most scratch resistant material. The Sapphire Glass used in the COROS APEX, APEX Pro and VERTIX is close with a rating of 9 Mohs making it extremely scratch resistant. 👍 This means rubbing up against tree branches, rocks and other common trail elements will have little to no impact on your watch screen. So get out and enjoy your next adventure with even more confidence in your COROS product! #exploreperfection #themohyouknow #mohs #sapphireglass #techtalk #gpswatch #trailrunning
