Some people, not naming names here, who tend to cut things tight have a time-honored tradition of setting their watches ahead by a few minutes. That way, when you glance at your watch and realize that you need to leave, you actually have a few more minutes. You can do this with your Apple Watch, but only on the watch itself. Press the Digital Crown to see your apps, tap Settings, scroll down to and tap Clock, tap the button for Set Watch Face Display Time Ahead, and use the Digital Crown to choose your desired time adjustment. Note that this setting affects only the time you see on the watch face. All alarms and notifications will come in at the correct times.
