Apple will hold an event March 9, the company said Thursday, amid speculation that the launch of the Apple Watch was near.

The invitation said simply "Spring forward." (Clocks spring forward one hour for daylight savings time the day before).

CEO Tim Cook has previously said the Apple Watch would ship sometime in April.

While the company showed off its smartwatch last October, it's expected that the tech giant will give more details about functionalities of the device.

One key thing investors will be looking to find out from the event is how long the battery life is for the device. Some reports have indicated that it could be as short as 2.5 hours, which could potentially affect sales of the smartwatch.

Another thing investors will be anxious to hear more about is what applications will be available on the device at launch.

"I really expect them to talk up third party applications. When the iPhone first launched it didn't have third party applications so it was all about what the phone could do out of the box. But what has happened with the iPhone and iPad is that what the third party developers bring to the table is a huge part of the appeal. And a huge part of what it is used for and why you would want it," said Jan Dawson, founder and chief analyst of Jackdaw Research, to CNBC earlier this month.

Apple has not yet announced full pricing details, but Cook has said that the Sport model would start at about $350. However, some speculate that the higher-end Watch Edition, which features a 18-karat gold casing, could cost as much as $5,000.

Besides the smartwatch, there's also some speculation that the tech giant may reveal a new music streaming service at the event.

Apple is rumored to be launching a Beats-powered subscription service sometime this year and given that the watch would likely have some sort of integration with that streaming product, there's the possibility the company might unveil the new music platform at the event as well.

"The subscription service seems like an obvious bet because the timing seems to be about right," Dawson told CNBC.
