Blood Oxygen app measurements are not intended for medical use, including self-diagnosis or consultation with a doctor, and are only designed for general fitness and wellness purposes.
ECG app is available on Apple Watch Series 4 and later (excluding Apple Watch SE) and can generate an ECG similar to a single-lead electrocardiogram. Intended for use by people 22 years old and over.
Irregular rhythm notification requires the latest version of watchOS and iOS. It is not intended for use by people under 22 years old or those who have been previously diagnosed with atrial fibrillation (AFib).
The temperature sensing feature is not a medical device and not intended for use in medical diagnosis, treatment, or for any other medical purpose.
Emergency SOS requires a cellular connection or Wi-Fi calling with an internet connection from your Apple Watch or nearby iPhone.
The international emergency calling feature requires an Apple Watch Ultra 2 (Cellular), Apple Watch Series 9 (GPS + Cellular), or Apple Watch SE (GPS + Cellular) model. For a list of supported countries and regions, see apple.com/watchos/feature-availability.
Apple Watch Ultra 2 has a water resistance rating of 100 meters under ISO standard 22810. It may be used for recreational scuba diving (with compatible third-party app from the App Store) to 40 meters and high-speed water sports. Apple Watch Ultra 2 should not be used for diving below 40 meters. Water resistance is not a permanent condition and can diminish over time. All-day battery life is based on the following use: 180 time checks, 180 notifications, 90 minutes of app use, and a 60-minute workout with music playback from Apple Watch via Bluetooth, over the course of 36 hours; Apple Watch Ultra 2 (GPS + Cellular) usage includes a total of 8 hours of LTE connection and 28 hours of connection to iPhone via Bluetooth over the course of 36 hours. Battery life in Low Power Mode is based on the following use: 360 time checks, 360 notifications, 180 minutes of app use, and two 60-minute workouts with music playback from Apple Watch via Bluetooth, over the course of 72 hours; Apple Watch Ultra 2 (GPS + Cellular) usage includes on-demand LTE connection and 60 hours of connection to iPhone via Bluetooth over the course of 72 hours. Testing conducted by Apple in August 2023 using preproduction Apple Watch Ultra 2 (GPS + Cellular) paired with an iPhone; all devices tested with prerelease software. Battery life varies by use, configuration, cellular network, signal strength, and many other factors; actual results will vary.
Apple Watch Ultra 2 is rated IP6X dust resistant.
Tested against subsections for Altitude, High Temperature, Low Temperature, Temperature Shock, Immersion, Freeze/Thaw, Shock, Vibration.
Ultra Wideband availability varies by region.

Apple Watch Ultra 2, Apple Watch Series 9, and Apple Watch SE require iPhone Xs or later with iOS 17 or later.
Features are subject to change. Some features, applications, and services may not be available in all regions or all languages.
