Since the switch to winter time, the dimmed screen on some Apple Watches has been running an hour fast
Apple acknowledges the bug in a support document and offers two quick fixes; anyone who does nothing will see the problem disappear on its own after midnight.
A week after Belgium and the rest of Europe put their clocks back an hour on 25 October, Apple has acknowledged a bug in the Apple Watch. In a support document dated 30 October, the company writes that after a time change the Always On display can keep showing the wrong hour while the wrist is down. Tapping the screen or raising the wrist does show the correct time. According to Apple, alarms work normally.
The first reports came on 26 October, when a few users in the United Kingdom and central Europe running watchOS 27 said on the MacRumors forum that their watch was still on summer time while at rest, Android Headlines wrote. The problem also appeared in StandBy mode. Which models and which watchOS versions are affected was not clear at the time. In most American states the clocks went back on Sunday 1 November, so users there may now see the bug too.
Apple recommends two fixes, iClarified sums up: temporarily choose a different watch face and then switch back to the usual one, or restart the watch using the side button. If you do nothing, Apple says the problem disappears on its own at midnight after the time change. The company also asks users to keep watchOS up to date, but has not yet announced a specific update.
