Apple Watch SE 3 requires iPhone 11 or later with iOS 26 or later.
The Vitals app is for wellness purposes only and not for medical use.
Fast charging is compatible with Apple Watch Series 7 and later, any Apple Watch Ultra model, and Apple Watch SE 3.
Battery life varies by use and configuration. See apple.com/watch/battery for more information.
The temperature sensing feature is not intended for medical use. Temperature sensing is available only on Apple Watch Series 8 and later and all Apple Watch Ultra models.
Sleep apnea notifications are available on Apple Watch Series 9 and later, Ultra 2 and later, and SE 3. The feature is intended to detect signs of moderate to severe sleep apnea for people 18 years old or older without a diagnosis of sleep apnea.
Irregular rhythm notification requires the latest versions 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).
Testing conducted by Apple in July and August 2025 using preproduction Apple Watch SE 3 (GPS + Cellular) and Apple Watch SE 2 (GPS + Cellular), each paired with an iPhone; all devices tested with prerelease software, Apple Watch Magnetic Fast Charger to USB-C Cable (Model A2515), and Apple 20W USB-C Power Adapter (Model A2305). Charge time varies with adapter, region, settings, initial battery levels, usage, and environmental factors; actual results will vary.
Requires an Apple Intelligence–enabled iPhone nearby and Bluetooth headphones with device and Siri language set to English. Apple Intelligence is available in beta. Some features may not be available in all regions or languages. For feature and language availability and system requirements, see support.apple.com/en-us/121115.
Emergency SOS requires a cellular connection or Wi-Fi calling with an internet connection from your Apple Watch or nearby iPhone. You can use cellular models of Apple Watch to make an emergency call in many locations, provided that cellular service is available. Some cellular networks may not accept an emergency call from your Apple Watch if your Apple Watch isn’t activated, if it isn’t compatible with or configured to operate on a particular cellular network, if isn’t set up for cellular service, or if the cellular network does not support emergency calling over IMS.
