Ultra 4 is a rugged powerhouse

Everything you need to know about the new Apple Watch features

The Apple Watch Ultra 4 houses Series 12 features inside a 49mm titanium fortress. It costs $799 and is built for extreme conditions and outdoor adventurers.

Battery life is genuinely astounding

The Ultra 4 achieved 74 hours of real-world battery life in testing. That's over three days of continuous use without charging.

Faster chip powers snappier Siri

The S11 chip inside delivers rapid Siri AI responses. This generation is noticeably quicker than its predecessor.

Overhauled sensors track your heart

Overhauled sensors track your heart

An upgraded sensor suite enables continuous heart rate tracking. The improvements give you better health insights throughout the day.

Big titanium design feels substantial

The Ultra 4 comes in a single 49mm titanium case in black or natural finish. It's noticeably large and heavy at 2.22 ounces, so it won't suit everyone.

Slightly heavier than Ultra 3

The Ultra 4 weighs 2.22 ounces compared to the Ultra 3's 2.17 ounces. Both share the same 49 by 44 by 12mm dimensions.

Multiple band options available

You can choose from several bands in various materials and colors to customize the look. The tester used a Sand Trail Loop band.

Series 12 remains the safer choice

The $399 Apple Watch Series 12 is still the Editors' Choice for most iPhone users. It offers more size and case options for a wider range of buyers.

Ultra 4 for power users only

The Ultra 4 is in a class of its own for outdoor adventurers and power users demanding ultimate endurance. It's not for casual smartwatch wearers.

Three-day battery changes everything

Going 74 hours without charging means you can wear the Ultra 4 through multi-day trips, camping, or hiking without worrying about power.

Premium price for premium endurance

At $799, the Ultra 4 costs double the Series 12. That premium buys you titanium durability, extreme battery life, and rugged design.

Built for the outdoors, not daily wear

The Ultra 4 keeps the rugged adventuring credentials of its predecessor. It's engineered for extreme conditions, not everyday casual use.

The headline

The Apple Watch Ultra 4 delivers three-plus days of real-world battery life, making it the ultimate smartwatch for people who need endurance over everything else.
