Apple found a bug in WatchOS2 and is NOT releasing the update today

Apple just postponed the release of watchOS 2, the first major update to the Apple Watch's operating system, after discovering an unspecified bug in the software. 

Today's launch of iOS 9 will proceed as planned, but Apple Watch owners will need to wait a bit longer for native third-party apps and other new features included with watchOS 2.

Finally Apple Said, We have discovered a bug in development of watchOS 2 that is taking a bit longer to fix than we expected. We will not release watchOS 2 today but will shortly.
