The post on Reddit reads, “The owner received the product on October 8. The owner slept with the watch on the wrist on October 9 night. Woke up on October 10 just to find the wrist is very hot. The owner quickly took off the watch to find the red wrist due to heat. No power signals from the watch, but the sound plays well when the watch is searched with the Find my Watch feature. The owner exchanged the device with a new product on October 16.”
What’s interesting is that the overheating mostly seems to be in the same place, at the top right corner of the display near the digital crown. It is unclear what is causing the overheating as there is no teardown of the device yet, but it has been speculated it could be due to the display connectors located near the Taptic Engine.
So far the problem seems to be limited to South Korea, but it is possible that it could be happening to other users in other markets that haven’t been reported yet. We’re not sure how Apple plans to respond to this, but this is actually not the first time we’ve heard about the Apple Watch overheating and burning the wearer, although thankfully this is a pretty rare occurrence.
