During its keynote on September 9, 2025, Apple unveiled three new smartwatch models: the Apple Watch Series 11, the Apple Watch Ultra 3, and the Apple Watch SE 3. We’ve compiled all the important information.

The presentation in Cupertino introduced a range of innovations that significantly expand Apple’s smartwatch portfolio. While the Apple Watch Series 11 features a more robust display glass and enhanced health functions, the Apple Watch Ultra 3 focuses on satellite communication and a larger display. The more affordable Apple Watch SE 3 now includes an always-on display and offers numerous features previously reserved for the more expensive models.

What the Apple Watch Series 11 Can Do

The Apple Watch Series 11 is available in 42 and 46 millimeter sizes and features glass that is twice as robust as its predecessor. Apple uses Ion-X glass and a ceramic coating. Color options include Space Gray, Diamond Black, Rose Gold, Silver, and Titanium variants. New in health is the sleep index, which provides information on recovery based on sleep data.

Additionally, Apple introduces a high blood pressure warning, though it is not medically certified. Both features are also available for older models starting from Series 9. Technically, the Series 11 offers AI-powered features with watchOS 26, such as the Smart Stack and Workout Buddy. It also includes 5G support, which is expected to extend battery life to up to 24 hours.

The Ultra 3 retains the 49-millimeter case but gets a new LTPO3 display with narrower bezels and wide-angle technology. It is the largest display Apple has ever installed in a watch, now allowing the display of a second hand in always-on mode. For athletes, the watch remains water-resistant up to 10 ATM, including a dive mode. The sleep index and high blood pressure warning are also available here.

As a technical highlight, Apple integrates satellite communication for the first time. This allows SOS messages to be sent, locations to be shared, or contacts to be informed. Usage is free for the first two years. Apple states the battery life is up to 42 hours.

After a three-year hiatus, Apple is releasing a new version of its entry-level smartwatch. For the first time, the SE 3 features an always-on display and particularly robust glass. Additionally, the speaker can be used directly for music or podcasts. New is the skin temperature measurement, which helps with cycle tracking, among other things. The sleep index and sleep apnea detection are also integrated.

With the S10 chip from the Apple Watch 10, the SE 3 now supports gesture control and Siri when no internet connection is required. Other new features include 5G in the cellular version, a battery life of up to 18 hours, and fast charging: enough energy for eight hours can be charged in just 15 minutes.

Prices, Availability, and Initial Assessment

All three models have been available for pre-order since September 9, 2025, and will be released on September 19, 2025. Prices start at 449 euros for the Apple Watch Series 11, 899 euros for the Apple Watch Ultra 3, and 269 euros for the Apple Watch SE 3.

COMPUTERBILD author Christian Just was able to personally examine the new smartwatches on-site in Cupertino. His impression: Externally, the watch has changed little, but the new blood pressure warning proves to be extremely practical. While Apple does not display exact values, it reliably informs users as soon as significant deviations upward occur–a sensible compromise.
