Apple Watch

This is the Apple Watch (1st generation), a smartwatch that was first introduced by Tim Cook at Apple's "Wish we could say more" keynote on 9 March 2015. Internally, the watch is referred to as N27aAP (Watch1,1 - 38mm) or N28aAP (Watch1,2 - 42mm).

Application Processor

This device uses the new Apple S7002 (S1) processor which is based on the ARMv7k (32-bit) architecture.

Specifications

• RAM: 512 MiB
• BCM4334 Wi-Fi chip from Broadcom
• NAND size: 8 GiB; roughly 2 GB are for songs and 75 MB for photos.
• Display: Retina.
• Screen: Sapphire crystal (Apple Watch and Apple Watch Edition) or Strengthened Ion-X glass (Apple Watch Sport)
• Compatibility: iOS 8.2 or later running on an iPhone 5 or newer

Operating System

The Apple Watch runs a slimmed down version of iOS 8. The user interface is managed by "Carousel" (instead of Springboard). Most frameworks are replaced with "Nano" equivalents.

Variations

• Apple Watch
• Apple Watch Sport
• Apple Watch Edition

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".

Announced third-party apps include (but are not limited to):

• American Airlines (B06)
• BMW
• City Mapper (E10)
• Comedy Central (A04)
• Facebook
• HoneyWell (B07)
• Lutron (C07)
