Apple has published a support document describing what to do if your Apple Watch continues to show time that's off by one hour after daylight savings time changes. "This incorrect time appears only on the Always On display when your wrist is down," says Apple. "When you activate the display by tapping it or raising your wrist, the time changes to the correct hour". To fix the issue, Apple says to switch to another watch face then back again, or to restart your watch.
