iTunes 10.7 user here (the last version before that crappy redesign). iTunes 10.7 is now 2.5 years old. Since yesterday I cannot access my iTunes account details anymore. App just keeps asking for my password again and again.

Don't expect your watch to have support for more than 2 years.

What if you update it ? Software sometimes requires some crucial back-end changes and can't be supported to infinity.
