Apple Watch Ultra debuts as a giant & rugged titanium model

Apple Watch Ultra is made for the most extreme conditions

The Apple Watch Ultra departs from what is offered by the Apple Watch Series 8 in a number of areas. The larger 49mm display, sapphire glass, aerospace titanium, and bright orange Action Button set this device apart.

Everything about the Apple Watch Ultra was built with advanced sensors and equipment to help users in many extreme conditions. For example, there's an additional GPS L5 GPS module for improved triangulation, even where the standard L1 GPS usually fails.

The WR100 rating lets users dive to 100 meters below the surface. When diving, the Apple Watch will begin displaying the depth on the watch face.

Another change is to the side, as the Digital Crown and side button are now placed on a small extended section on one edge. The Digital Crown is slightly sunk into this section, partly to add more protection.

The Action Button is international orange and can be pressed to activate special functions in certain conditions. It can be customized to launch certain apps or functions with a single press.

Users can get up to 36 hours of battery life on a single charge. The new low-power mode extends this battery life to 60 hours.

On the inside, the Apple Watch Ultra uses the new S8 chip. It also has access to the same sensors as the Apple Watch Series 8, like the new temperature sensor.

"Inspired by explorers and athletes from around the world, we created an entirely new category of Apple Watch designed for new and extreme environments — it's the most rugged and capable Apple Watch yet," said Jeff Williams, Apple's chief operating officer. "Apple Watch Ultra is a versatile tool that empowers users to push their boundaries with adventure, endurance, and exploration."

There are three new bands for the Apple Watch Ultra — Trail Loop, Alpine Loop, and Ocean Band. They are custom-made with different extreme activities in mind.

Pre-orders begin later Wednesday, and devices ship on September 23. All Apple Watch Ultra models are $799.
