Apple's watchOS 10 will officially be available on September 18, the company announced during its iPhone 15 launch event today. The update is simultaneously one of the biggest facelifts ever for watchOS, while also being a throwback to the original "Glances" feature from the original Apple Watch. Instead of focusing on individual apps, WatchOS 10 relies on widgets in every watch face — just turn the Digital Crown and you'll have quick access to things like timers, music, or a podcast episode that you're listening to.
