Apple on Thursday sent out invites for a special event to be held on March 9, 2015. The event will be held in San Francisco at the Yerba Buena Center for the Arts, a venue that Apple has used many times before for special events.

It is widely expected that Apple will use the event to give more details about the Apple Watch, which was introduced last September.

There are still many details about the Apple Watch that we don’t know, including pricing of the various configurations that we could find out in March.
