Can't adjust the Apple Watch alarm time

My wife figured it out. The cylindrical button on the right side of the watch body rotates.

I love your wife right now. I spent 4 hours trying to find this answer.

Your wife is a genius

Oh, it's called the Digital Crown :)

Are you trying to do it like this? https://help.apple.com/watch/#/apd27ce65478

Select options for an alarm. Open Alarm Clock , then tap the alarm switch to turn it on or off, or tap the alarm time to change its settings. Set repeat, label, and snooze to suit you.

You have to tap the "Change Time" text. Does that not work?
