The Digital Crown worked fine this morning when I put it on. Then a couple of hours later, I went to change the color on my face and the crown wouldn't turn. I got it to turn a little and next thing I know, there's a rubber ring hanging out of it. I made an apple genius appointment. Soonest I can get there is Friday. The crown is as smooth as butter now. Is there any danger in using the watch until my appointment? Is this something that they'll fix? My son didn't get apple care.
