With this case, your Apple Watch 4, 5, 6, and SE (40 mm) becomes waterproof and is also resistant to drops and impacts of all kinds. The watch's functions, such as the heart rate monitor, charging at the dock or via cable, and the microphone, can still be used with the case. The slim design of the Apple Watch is maintained, and the buttons as well as the Digital Crown remain fully functional. This allows you to use the watch anywhere, whether in the shower, in the snow, at the beach, or in the woods while downhill biking. Additionally, the case comes with a sturdy NATO nylon band, so you can protect your original watch band, whether it's the sport, leather, or metal band. Not compatible with the Ceramic Model of the Apple Watch 4 and 5.
