Apple announced its latest rugged wearable, the Apple Watch Ultra 4, during its "Surprise and Shine" iPhone event on Wednesday. It's joined by the new flagship Apple Watch Series 12, some new AirPods, the new iPhone 18 Pro and Pro Max, and the long-rumored foldable iPhone Duo.
The Apple Watch Ultra 4 will start at $799, the same price as last year's Apple Watch Ultra 3. It also has the same design as its predecessor, but adds faster performance, a longer battery life, and new health and fitness features. Here's a rundown of its upgrades.
The Apple Watch Ultra 4 introduces new Health Sensing System, S11 chip
The Apple Watch Ultra 4 is the latest iteration of Apple's biggest, most durable, and most expensive smartwatch. In a press release, the company called it "the ultimate sports and adventure watch" and "the most comprehensive wearable across health, fitness, and safety."
The Apple Watch Ultra 4 supports a new Health Sensing System that takes more accurate, continuous heart rate readings. That includes more heart rate variability (HRV) measurements to gauge cardiovascular stress and recovery indicators, Apple said. Users will be able to compare their daytime and nighttime HRV measurements.
The Health Sensing System also adds a Readiness fitness score that tells the user how prepared they are for certain workout activities based on past training sessions.
The Apple Watch Ultra 4 will work with iPhones' newly revamped Health app (out later this year), which will have a Longevity tab and use vision-based AI models to analyze users' movements for flexibility, balance, and more.
The Apple Watch Ultra 4 runs on the new S11 chip, which will power new "Audio Intelligence" features (also coming later this year). These include a "Live Rewind" tool that can transcribe 15 seconds of conversations, "Siri Recap" conversation summaries, and "Sound Recognition" alerts for users who are deaf and hard of hearing.
Privacy-wise, Apple said Audio Intelligence features "do not create or store audio recordings," and that raw audio is processed separately from the rest of the system before it's deleted. Apple, on-board apps, and even the user themselves can't access it.
The Health Sensing System, redesigned Health app, and Audio Intelligence features will also be available on the standard Apple Watch Series 12.
The Apple Watch Ultra 4 will offer up to 50 hours of battery life, up from 42 in the previous generation. In low power mode, it maxes out at 84 hours per charge. Apple said its "charging is now faster than ever," with just 15 minutes on an outlet translating to 18 hours of use.
The Apple Watch Ultra 4's case comes in the same standard colors as the Ultra 3 — black titanium and natural titanium — but its Alpine Loop, Trail Loop, and Ocean Band come in new hues. A luxe Apple Watch Hermès Ultra 4 variant will be available with a new extendable Grand H titanium band for $3,149. (It otherwise starts at $1,499.)
The Apple Watch Ultra 4 is set for release on Friday, Sept. 18, and preorders begin today.
