Apple has unveiled its long-rumoured smartwatch called the Apple Watch, unveiling multiple models of the device and touting it as an entirely new form factor for the company. However, the device will not be available until 2015.
Powered by a custom designed S1 chip, Apple Watch comes in two different sizes, and three versions called Apple Watch Edition, Apple Watch and Apple Watch Sport.
The watch can be controlled via voice controls or what Apple calls a "digital crown" which reworks the analogue crown traditionally found on watches to translate rotary motion into digital data.
The digital crown allows Apple Watch wearers control the apps on the watch and make zooming possible on a small screen. The crown can also be pushed to activate Apple's virtual assistant Siri or act as the home button like the iPhone.
Below the digital crown sits what Apple calls a "digital touch" button that gives quick access to wearers favourite contacts.
Describing how Apple Watch is controlled Apple's chief executive Tim Cook said: "A breakthrough in user interface was required. What we didn't do is take the iPhone and shrink the user interface and slap it on your wrist."
As such, the watch's apps are displayed in a honeycomb pattern designed to fit apps such as photo and maps apps onto a small screen.
Explaining the design logic behind Apple Watch, Apple's design guru Jonathan Ive said: "You can't determine a boundary between the physical object and the software."
In order to blur these boundaries, Apple Watch provides audio and haptic feedback to alert wearers of incoming notifications.
The sapphire glass Retina display on the watch is also flexible allowing it to tell the difference between a tap and a press. The Apple Watch can be charged through its backplate via inductive charging.
Behind the zirconia back plate sits four infrared and visible light LEDs and photosensors to detect a wearers pulse, which helps give provide biometric data to work with Apple's fitness apps.
Alongside fitness functions, Apple Watch also includes Apple Pay, which allows the smartwatch to be used for making contactless payments.
Cook said that the device was designed to be "incredibly customisable" and as such, features six different straps and allows wearers to change the clock faces to suit their preferences.
Three different editions of Apple Watch will be available, and prices will start at $349, roughly £216. Apple Watch, Apple Watch Sport and Apple Watch Edition will all be available early 2015.
