There may be a problem with the new Apple Watch SE, which some users say overheats after a few hours of use. Several “Apple Watch SE” owners in South Korea have experienced issues, as reported in a Reddit article chronicling the complaints.
There have been six reports from “Apple Watch SE” owners in South Korea who have seen their Apple Watches heat up and malfunction, with a yellow spot appearing in the upper right corner of the watch.
All of the owners who had issues wore the watch when it got hot on the wrist or while charging and then it showed a display issue. As described on Reddit:
The owner received the product on October 8. The owner slept with the watch on his wrist on the evening of October 9. I woke up on October 10th just to find my wrist very hot. The owner quickly removed the watch to find the red wrist due to the heat. No power signal from the watch, but the sound is played well when the watch is searched with the Find My Watch function. The owner traded in the device for a new product on October 16.
There hasn’t been a teardown of the Apple Watch SE, so it’s unclear what might be causing the issue, but as noted on Reddit, if it’s similar in design to previous models, it could be the display connectors near the Taptic Engine.
It is not known why this problem appears to be confined to South Korea, but we have not found any other reports on the issue on the MacRumors forums, Apple support communities, or social media. There may be a specific issue with watches made in a certain region and shipped to South Korea, or it could be a more widespread issue and the reports just haven’t arrived yet.
