During update my S4 Nike+ 44 mm got stuck on the Apple logo. After several hours I tried to reboot the watch by pressing both buttons until the screen went blank. The logo popped up again. The solution was to keep pressing the two buttons until the logo disappeared the second time, then the screen remained blank. Putting the watch on the charger immediately pops up that irritating white apple again. I called Apple support and they scheduled me for a meeting at Apple Store in Malmö (Sweden) for a repair. I got the first available time which is on Monday, 5 days from now. As I understand they can’t do anything else but sending it away to a repair center. It sounds weird to use the wording repairing an electronic device due to a failing software update.
