Do you wear an iWatch to the temple? Concerned with you watch coming on when you raise your hand? There is a simple solution, and you don't involve learning your watch at home.
Set your watch to theater mode by swiping up and tapping on "Theater Mode." Now the watch will only come on when you tap it and notifications are silenced.
Also, create a photo face of the Savior so when you do check the time you also see Him.
