CUPERTINO, Calif.—The third and final new Apple Watch introduced at Apple's hardware-reveal event today is the company's first stab at a premium, trail-ready piece for your wrist: the Apple Watch Ultra.

Apple COO Jeff Williams described the new model, which starts at $799 and can be ordered starting today, as an option for "exploration, adventure, and endurance," and its features seem designed for the highest hikes and deepest dives. The Apple Watch Ultra includes deep water resistance (it's EN13319 certified), a siren that can be heard up to 600 feet away, and high-end physical materials. The 49 mm case is composed of "aerospace titanium," while the new "alpine loop" wristband combines titanium with woven fabric.
