Apple began inviting media to a March 9th event called "Spring Forward," as first reported by The Loop. The name and timing alike both suggest the event will focus on the Apple Watch.

The company will hold the event at the Yerba Buena Center for the Arts in San Francisco, one of Apple's go-to locations for media events.
Apple unveiled the Apple Watch at a September media event, but we don't yet know pricing (it will start at US$349), details about battery life, and many other specifics about how the device will work. Apple CEO Tim Cook said recently that Apple Watch will ship in April.
