Apple Watch expected to be launched at the company's March 9 event

San Francisco: Apple sent out invitations for a media event in San Francisco on March 9, about one month before the much-anticipated launch of the new Apple Watch.

The world's largest technology company did not specify what the event will be about in the invitation which reads simply "Spring Forward," a word play on the resetting of watches for daylight saving time.

Chief Executive Tim Cook said last month that the company plans to launch the smartwatch in April. The watch, which will let consumers check their email, pay for goods at retail stores and monitor personal health information, represents Apple's first major new product introduction since the 2010 launch of the iPad.

Shares of Apple were up 88 cents at $129.67 on Thursday.
