Emergency SOS requires a cellular connection or Wi-Fi Calling with an internet connection from your Apple Watch or nearby iPhone.
Apple Watch SE has a water resistance rating of 50 meters under ISO standard 22810:2010. This means that it may be used for shallow-water activities like swimming in a pool or ocean. However, Apple Watch SE should not be used for scuba diving, waterskiing, or other activities involving high-velocity water or submersion below shallow depth. Water resistance is not a permanent condition and can diminish over time. For additional information see support.apple.com/en-us/HT205000.
The international emergency calling feature requires an Apple Watch Ultra (Cellular), Apple Watch Series 8 (GPS + Cellular), Apple Watch Series 7 (GPS + Cellular), or Apple Watch SE (GPS + Cellular) model. For a list of supported countries and regions, see apple.com/watchos/feature-availability.
Wireless service plan required for cellular service. Contact your service provider for more details. Connection may vary based on network availability. Check apple.com/watch/cellular for participating wireless carriers and eligibility. See support.apple.com/en-us/HT207578 for additional setup instructions.
International roaming coverage is determined by your carrier. Please check with your carrier for details. For a list of supported carriers, see apple.com/watch/cellular.
All-day battery life is based on the following use: 90 time checks, 90 notifications, 45 minutes of app use, and a 60-minute workout with music playback from Apple Watch via Bluetooth, over the course of 18 hours; Apple Watch SE (2nd generation) (GPS) usage includes connection to iPhone via Bluetooth during the entire 18-hour test; Apple Watch SE (2nd generation) (GPS + Cellular) usage includes a total of 4 hours of LTE connection and 14 hours of connection to iPhone via Bluetooth over the course of 18 hours. Testing conducted by Apple in August 2022 using preproduction Apple Watch SE (2nd generation) (GPS) and Apple Watch SE (2nd generation) (GPS + Cellular), each 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.
Results based on the performance of common user tasks. Testing conducted by Apple in August 2021 using preproduction Apple Watch Series 7, and shipping Apple Watch SE, each paired with an iPhone; all devices tested with prerelease software. Results reflect the approximate performance of Apple Watch.
