Had the sticky/stiff Digital Crown thing... did the warm water rinse while turning and pressing crown that Apple recommends in this advisory. As I was drying it, I noticed a bit of black stuff in the gap, so I scraped it out with my fingernail. Out comes a broken O-ring seal! No wonder it was stiff. Booking an appointment with a Genius - is this a fix or a replacement? Will be Watchless for a while?
