Apple Watch (1st generation)



The Apple Watch is a smartwatch that was first introduced by Tim Cook at Apple's "Wish we could say more" keynote on 2015. Internally, the watch is referred to as N27aAP (Watch1,1 - 38mm) or N28aAP (Watch1,2 - 42mm).

Third-party applications
Third-party applications are supported through the WatchKit API. However, in order to save battery and allow a less powerful processor, applications are "run" on the phone and streamed to the Watch over Bluetooth. iOS 8.2 (and up) comes with a dedicated "Watch" app to perform the initial pairing and download third-party "Watch apps".

 * American Airlines (B06)
