With a new health-sensing system, a faster S11 chip, a longer battery life, and other features targeted at athletes and outdoor users, Apple has formally unveiled the Apple Watch Ultra 4.
The most recent Ultra model, which comes in black and natural titanium, is priced at $799 in the United States. According to Apple, the watch will go on sale in stores on September 18, 2026.
A Tougher Apple Watch
The Apple Watch Ultra 4 continues Apple’s focus on durability and outdoor use. It’s a watch with a titanium case and a sapphire crystal face, built to stand up to rough conditions.
The Ultra 4 is MIL-STD-810H tested and has an IP6X dust-resistance rating, says Apple. It also features a WR100 water-resistance rating and is designed for recreational scuba diving to a depth of 40 meters.
The watch comes in two finishes: natural titanium and black titanium.
The rugged construction is one of the major reasons to consider the Ultra line for hikers, runners, divers and other outdoor users.
New Health Sensing System
Health Tracking is one of the biggest changes coming to the Apple Watch Ultra 4.
Apple has announced a new Health Sensing System that combines new optical and electrical sensors. The company says the system is the most accurate heart rate sensing it has ever done in a wearable.
During the day the watch can record heart rate every 5 seconds. It also offers more frequent heart rate variability measurements, providing users with more information about fitness, stress and recovery.
Apple has also introduced a new feature called Readiness. It looks at things like recent activity, training load, vital signs and sleep, before giving a daily score out of 10.
The score is accompanied by guidance such as Recover, Pace Yourself, Ready or Go For It, giving users an easier way to get a sense of how ready their body may be for the day ahead.
Up to 50 Hours of Battery Life
Battery life has also been a big thing.
Apple says the Apple Watch Ultra 4 can achieve 50 hours of normal use, and Low Power Mode can stretch that to as much as 84 hours under Apple’s testing conditions.
Now outdoor athletes have new options for longer workouts.
The long lasting workout mode can track outdoor workouts with GPS and heart-rate measurements for up to 25 hours. If you’re doing something longer, Max Extended Workout mode can track outdoor runs, walks and hikes for up to 45 hours.
Quicker charging as well. Apple says that under its testing conditions, a 15-minute charge can provide up to 18 hours of battery life.
Better GPS for Outdoor Adventures
The Ultra experience still heavily relies on navigation.
According to Apple, the Ultra 4 sports watch offers the most precise on-device GPS. Because of this, the watch should be especially helpful for running, trekking, and visiting new places.
Additionally, the watch keeps its satellite communication features, which are intended to keep users secure and connected when they are not near cellular or Wi-Fi service.
The S11 Chip Brings More Intelligence
Apple's latest S11 chip powers the Apple Watch Ultra 4.
In addition to enhancing performance, watchOS 27's new intelligent functions are supported by the chip. With features intended to offer more individualized context and access to a wider range of information, Apple is introducing Siri AI to the watch.
Additionally, the Ultra 4 adds Audio Intelligence features including Live Rewind, Sound Recognition, and Siri Recap. Later in 2026, some of these functions will be available, however they might have geographical, device, and language restrictions.
Who Is the Apple Watch Ultra 4 For?
It's obvious that the Ultra 4 is intended for users who desire features beyond those of a smartwatch.
Its lengthy battery life, GPS capabilities, workout monitoring, and sturdy build are advantageous to runners, hikers, divers, and serious outdoor users. People who desire more specific information regarding training, recuperation, and daily activities will find it intriguing due to the added health features.
However, the Ultra 4's high price and durable build might be too much for someone who primarily needs notifications, texts, and basic fitness tracking.
Apple Watch Ultra 4 Price and Availability
In the US, the Apple Watch Ultra 4 is priced at $799.
Natural and black titanium coatings will be available starting on September 18, 2026, according to Apple. Trail Loop, Alpine Loop, and Ocean Band options are available in a variety of colors.
Final Thoughts
There is more to the Apple Watch Ultra 4 than just a design change. The S11 chip, a new health-sensing system, enhanced GPS, extended battery life, and other smart features are all included in Apple's most recent tough wristwatch.
Its primary attraction is still the same as that of earlier Ultra models: it is intended for users who desire a smartwatch that can withstand strenuous exercise and outdoor excursions.
The Ultra 4 is especially designed for customers who spend a lot of time away from a charger, offering up to 50 hours of normal-use battery life and up to 45 hours of Max Extended Workout monitoring.
