Shield your 42mm Apple Watch against scratches and impacts with this X-Doria Defense Edge 62-0883-05-XP case, which features a machined-aluminum exterior and a soft rubber interior to guard your device against damage.
I like that it protects to watch case, but it feels a little sharp on the edges. Once it is on my wrist I don't usually notice it as it doesn't catch on my clothes. Overall I like changing the outside color of my watch and protecting it at the same time.
