Apple has updated the Apple Watch website with more info about this awesome watch. You can apparently customize the different watch faces a lot. You can even add small widgets called “complications” to the watch faces. Hopefully it will be possible for third-party developers to create these complications widgets too.

Apple notes that different watch faces will allow you to toggle between colors with various levels of time including “minutes, seconds, and milliseconds.”
The site also details additional utilities called “complications” that can appear on some watch faces noting that tapping a certain complication will open its specific app so they act as shortcuts.
