After a last minute delay last week due to an unforeseen bug, WatchOS 2 is now available for Apple Watch. The new version brings a lot of must-have upgrades including new watch faces, third-party complications, and support for third-party apps. Basically, this is what the Apple Watch should have been at launch.
To download the new wrist-based OS, pair your watch with an iPhone, head over to the watch app and go to General > Software and then update. That's it.
Now get out there and use that new and improved wristputer of yours, you crazy kids.
