Apple Watch-Smart Watch

The Apple Watch runs a version of iOS that is simpler than its smartphone counterpart. You won't be able to make calls or use Web-based services from the watch without being connected to a compatible device (iPhone 5 and up, running the latest version of iOS 8). The Apple Watch pairs with iPhones via Bluetooth Low Energy and built-in Wi-Fi.
The Apple Watch features a 38mm-wide, 340 x 272-pixel rectangular touch screen (which increases to 48mm, 390 x 312p on larger models). This display is coated with sapphire to protect the device from scratches. Powered by Apple's new S1 chip.The watch is also sweat-resistant, and will juice up via a specially created MagSafe charger that attaches easily to the watch.
The Watch will be available in three collections: Apple Watch, Apple Watch Sport and Apple Watch Edition. The Watch model comes in a polished or space-gray stainless-steel watch case and a selection of straps: sport band, classic buckle, leather loop, modern buckle, Milanese loop and link bracelet. Each of those bands is available in a variety of colors. The Apple Watch Sport comes in either a space gray or silver anodized aluminum finish with a sport band, while the Apple Watch Edition features an 18-karat rose or yellow gold casing and a range of exclusive straps.
