Apple has already sent out invitations for a media event in San Francisco on March 9.

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.

Apple Inc has asked its Asian suppliers to make 5-6 million units of its three Apple Watch models for the first-quarter, the Wall Street Journal reported, citing people familiar with the matter.

Meanwhile, several big Asian phone companies launched new high-end smartphones and other wireless gizmos, hoping to challenge Apple in a big year for wireless gadgets.
