Some posts on Reddit and on Apple's discussion board talk about how their first-gen Watches' batteries ballooned and displaced the screens like what happened in the image above. It doesn't seem to be a huge issue, and we haven't seen anyone claim that their device exploded or caught fire like Samsung's Galaxy Notes did. Still, it's definitely good to know Apple can help if anything happens to your smartwatch, especially if you bought it when it was first released in 2015.
