Apple Watch costs $349 to $10,000, pre-orders start April 10

Make calls, read email, control music, manage Instagram photos, keep up with your workout, pay for groceries, open your hotel room door. CEO Tim Cook says you can do it all from your wrist with Apple Watch - for 18 hours a day. That's how long the battery will last. That's so if you factor in charging it while you sleep, but you wouldn't be able to use sleep-tracking apps overnight.

The watch is charged with a magnetic charger that clicks into place when it's near the back of the watch.

The watch will notify a wearer with a "tap" when a new email has arrived, for instance. You can use the watch for phone calls - the watch is connected to your iPhone using Bluetooth. "I have been wanting to this this since I was five years old. The day is finally here," Cook declares.

The watch will start selling on April 24 in the US, Australia, Canada, China, France, Germany, Hong Kong, Japan and the United Kingdom.

Pre-orders start April 10 and the devices will range from $349 to as much as $10,000 for a luxury edition. Industry watchers are eager to see if Apple's version will be the tipping point for the sluggish smartwatch market. There was similar skepticism when Apple released the iPad in 2010, yet the company has successfully sold millions and its popularity has shaken up the PC market.

The stakes are high for a company that just dislodged AT&T as one of the 30 stocks comprising the venerable Dow Jones industrial average. The watch is the first brand-new device Apple has launched without Steve Jobs.

Cook is directing Apple's big event Monday in San Francisco, unveiling a shiny, skinny and silent MacBook weighing in at just two pounds that the company says is the world's most energy-efficient laptop. Apple also has unveiled a new deal between Apple TV and HBO, touted growth in iPhone sales and Apple Pay adoption, and announced a set of tools called ResearchKit to help hospitals and research centers develop apps for patients.

It cut the price of Apple TV by $30 to $69 and is partnering with HBO to offer its stand-alone streaming service, HBO Go, on Apple devices in time for the "Game of Thrones" premiere April 12. It will cost $14.99 monthly. Cook said 2,500 banks are now signed up with Apple Pay, which is available in 700,000 retail locations nationwide.
