The Apple Watch is Apple's newest, most personal computer. It comes in two sizes — 38mm and 42mm; and three collections — the aluminum Apple Watch Sport, the stainless steel Apple Watch, and the gold Apple Watch Edition. The Apple Watch Sport starts at $349 while the Apple Watch Edition goes all the way to $17K.
Codenamed gizmo, the Apple Watch project began in 2011, championed by senior vice president of design, Jony Ive and his friend, and now official collaborator, Marc Newson. The device runs Watch OS, a variation iOS headed by vice president Kevin Lynch.
Instead of the traditional springboard home screen filled with super-elipse icons found on iPhone or iPad, the Apple Watch runs a carousel of round icons that change in scale and position. Instead of gestures for navigation, it uses a digital crown to handle scrolling and zooming, and a force press to bring up secondary actions. There's also a button beneath the crown that launches a friend interface or can be double-clicked to go into Apple Pay.
Developers can make apps for the Apple Watch using WatchKit. Currently WatchKit supports looks (notifications), glances (widgets), and WatchKit apps (remote views), with native apps coming later this year.
Apple has also made several other unique apps for the Apple Watch, including Fitness, Activity, and Workout for health and fitness, a remote viewfinder for the iPhone's camera, and more!
