Cracked the crystal on my first Apple Watch dropping it on a tile floor. Got this Otterbox case for my new one and it protects the crystal perfectly. It doesn't literally cover the glass, but it's raised edges keep the crystal from hitting any flat surface. The plastic case does decay a bit after a year or so and the rigid plastic frame fell out. But I gladly replaced the case cause it does the job well. It's priced a little high but so is my Apple Watch!
