The device has been specifically tailored for divers, allowing it 100 meters of water resistance and even the EN13319 certification standard for diving computers. Given its extreme scuba-prioritized features, the Ultra according to Apple can hit depths as far down as 40 meters, which is the equivalent of 131 feet and 2.8 inches.
The device features a state-of-the-art depth gauge made in partnership with Huish Outdoors, as well as a new Oceanic+ app that integrates all diving necessities into one place. The additional Depth app also gives divers specific readings, such as maximum depth reached, duration underwater, water temperature, current depth, and more.
