It's the first new product to be developed and introduced under Chief Executive Officer Tim Cook's reign, the next chapter in Apple's history.

The Apple Watch sports a flat screen with sapphire glass and has a 'digital crown' with a twisting control that lets the user scroll through different functions. It runs apps, takes dictation and interacts with the iPhone.
"With the Digital Crown, you can scroll, zoom, and navigate Apple Watch without covering the display," Apple said.
The watch has a gyroscope and an accelerometer that measures fitness. Besides, it uses the GPS and Wi-Fi in the users' iPhone to help track the distance.
It comes with colorful wrist bands (pink, blue and white) and styles like hand-crafted gold buckle.
Apple said: "Apple Watch will start at USD 349 and will be available early next year. It works with iPhone 5, 5c, 5s, 6, and 6 Plus."
The smartwatch has three variants -- Apple Watch, Apple Watch Sport, and Apple Watch Edition, which is made from 18-karat gold.

Apple also unveiled two larger iPhones and a mobile payments service on Tuesday.
The iPhone 6 will be priced at USD 199 (16GB), USD 299 (64GB) and USD 399 (128GB) with a two-year contract. The iPhone 6 Plus will be available for USD 299 (16GB), USD 399 (64GB) and USD 499 (128GB) with a two-year contract.
The new handsets will be available in the US, Canada, the UK and six other countries from September 19, while other countries will follow later. The devices can be pre-booked from September 12.
It may still take some time before the latest version of the iPhone makes it to India. Market analysts said the handsets are most likely to hit Indian shores either around Diwali in October end or in November like the previous launches in the country.
