This morning, when I took my Apple Watch (original series) off the charger, I noticed that the display was coming off. Naturally I decided not to wear it, and left it home this morning. Now, several hours later, the gap between the body and display has got bigger. I can only conclude that something is pushing the display off from inside the watch. The only thing that can do that is the battery swelling inside the watch body. Yesterday night, when I took the watch off to charge it overnight, there were no signs of anything being wrong with the watch. It has worked perfectly until now, and strangely enough, the watch still works. As the watch is about 2 years old, the warranty has expired. However, I wonder if a defect like this still falls under Apple's responsibility to fix? The watch hasn't been subject to any outside damage, so could this be the case of the battery just getting old and becoming defective? The battery has, however, lasted ~1,5 days in my use between charging, and I haven't noticed any shortening in battery life, so it hasn't appeared to be on its last legs. Photos: A watch in the price range of 42mm SS Apple Watch should last 2 years without defects. Naturally, I'm sending this to Apple Support as well. Has anybody come across a similar incident? To my understanding there has been no widespread issues with the Apple Watch battery.
