Apple's new iOS 11 operating system will be available to download on Sept. 19 for iPhone and iPad users.

More from CNBC:

Since there's no home button, Touch ID no longer exists on the front of the phone. Apple will allow users to unlock the iPhone X with their faces using a new feature called Face ID. Apple uses an infrared camera, a front-camera and other sensors to detect a user's face.

When you look at your iPhone, it will detect your face and will automatically unlock, even in the dark. Apple says it uses neural networks to create a mathematical model of your face and then compares that in real-time, invisibly, to make sure it's actually you. The A11 Bionic chip has a built-in neural engine to process your face, Apple said.

Apple said you can't spoof Face ID with photographs or even professionally made masks, which it said it had folks in Hollywood design to help enhance security. The phone won't unlock if your eyes are closed or if you're looking away.

On the surface, the devices look similar to its predesscor -- the iPhone 8 clocks in at 4.7 inches and iPhone 8 Plus is 5.5 inches. Inside is an A11 "bionic chip" and an improved camera sensor. There are new camera modes, including an expanded Portrait Mode that lets you change lighting effects after you take the shot.

The company also teased some of the new features coming to iOS 11, including augmented reality.

iPhone 8 smartphones, which come with an aluminum band around the edges, will be available in three colors: space gray, gold and silver. The iPhone 8 will start at $699 and the iPhone 8 Plus is $799 for 64 GB models.

Pre-orders start Friday, September 15 and hit stores the following Friday, September 22.

Apple also announced a new cellular Apple Watch, which CEO Tim Cook called the device the best-selling watch in the world. The waterproof Apple Watch has an even greater focus on fitness and health. For example, it flags users when it detects an elevated pulse.

The device was the first product unveiled inside the circular Steve Jobs Theater, part of Apple's brand new multi-billion dollar campus in Cupertino, California.

The event opened with a short inspirational video with featured audio by late Apple founder Steve Jobs.

"It seems only fitting that Steve should open his theater," Cook told attendees. "Steve meant so much to me and so much to all of us. There's not a day that goes by that we don't think about him. Memories especially come rushing back as we prepared for today and this event."

Cook also used his stage time to send thoughts and prayers to those impacted by Hurricanes Harvey and Irma.

The event comes a little more than ten years after Steve Jobs unveiled the very first iPhone on stage in San Francisco. That small rectangle has been responsible for making Apple one of the largest companies in the world. Now, the iPhone accounts for nearly 70% of Apple's revenue. Customers and investors have been waiting for a big iPhone upgrade, which Cook even blamed for slower than usual iPhone sales last year.

The press conference is the first time Apple has held a large event at its new "spaceship" campus, which is expected to be completed later this year.
