Most protective Apple Watch covers I’ve seen are crystal-clear, very simple little snap-over covers to protect your Watch from bumps and scratches. The GHIJKL case for Apple Watch series 2 and 3 is a clear TPU cover that fits over the metal sides of the Watch. It’s made of TPU, so it protects against bumps, just like you’d expect, but it adds a decorative element. It’s a bumper-style case, so it doesn’t cover the crystal itself.
The protective case is etched to make it look like the face is surrounded by cut crystals. The side button has these “diamond” designs, too. All buttons are usable through the cover, and you can charge the Watch without removing the protective case.
The GHIJKL protective case is designed for the 38mm Apple Watch. It’s $7.99 at Amazon.
