WatchOS 2, the upgrade of the operating system for the Apple Watch, adds a Time Travel feature. Nope, no Back to the Future or Looper possibilities here. But you can scroll with the Digital Crown to explore events in the future (and past).
Like what, you ask? You can check on upcoming meetings or activities. You can look at info from third-party apps, such as upcoming flight information. You can check what the weather will be a few hours from now. And more.
To use Time Travel, you'll need to use one of the watchOS 2 watch faces that support the feature. They include Chronograph, Solar, Color, Astronomy, Simple, Modular, Utility, and even Mickey Mouse.
If you have one of those watch faces enabled, you just twist the Digital Crown forward or backward to move that direction in time. Your watch face will change the time and show a little blue status icon that says Time Travel above the change in time you’ve enabled. When you’re done, firmly press on the Digital Crown to get back to the actual time.
To obtain watchOS 2, open the Apple Watch app on your iPhone (which must be running iOS 9) and tap through My Watch > General > Software Update. Make sure your watch is in Bluetooth range of your iPhone and connected to its charger.
