Five days ago Apple released iOS 9, the latest major release of their operating system for smartphones and tablets. They also planned to release the first major upgrade to watchOS, their operating system for the Apple Watch. Due to an unspecified bug that couldn't be fixed in time for the planned September 16th launch the release of watchOS 2 was delayed with no specific details about when it would be released other than that it would be soon. Five days later the bug has been fixed, and the update is now rolling out to users around the world.

The watchOS 2 update comes in at 517MB for the 38mm model, while the 42mm model may have a slightly larger update size due to higher resolution bitmaps and other assets. You can view our overview of what's new in watchOS 2 here, as well as on Apple's own watchOS 2 page.

    Only 12.4 MiB for me on my 42mm, but I was already running the latest wOS 2.0 beta. Good to know their system is intelligent enough to not have me DL the full official version.
