how to display the watch face

I fixed this. It turns out that pressing the Digital Crown did take me to the watch face, but to a different view of that face, namely, a view that was of calendar items. I swiped left and saw the time.

It sounds as if you have more than one watch face installed. You can switch between them by swiping. If you only want to have one on your watch, open the Watch app on your phone and tap "Edit" to the right of "My Faces". You can then delete the ones you don't want.

Have you tried pushing in the digital crown to go back to the watch face

Failing that have you tried a force reset by holding in the side button and the digital crown for 10 seconds till you see the Apple logo then release
