The Apple Watch Series 6 has a display that is always on. The Always-On Retina display is now significantly brighter outdoors when your wrist is down. So, you can see all the information on your watch face more easily than ever — without having to raise your wrist to wake your watch. 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.
The ECG app and irregular rhythm notification require the latest version of watchOS and iOS and are not intended for use by people under 22 years old. The ECG app is available on Apple Watch Series 4 or later (not including Apple Watch SE). The irregular rhythm notification is not designed for people who have been previously diagnosed with Afib.
Apple Watch Series 6 has a water resistance rating of 50 meters under ISO standard 22810:2010. This means that they may be used for shallow-water activities like swimming in a pool or ocean. However, they should not be used for scuba diving, waterskiing, or other activities involving high-velocity water or submersion below shallow depth. To use Emergency SOS on an Apple Watch without cellular, your iPhone needs to be nearby. If your iPhone isn’t nearby, your Apple Watch needs to be connected to a known Wi-Fi network and you must set up Wi-Fi Calling.
All-day battery life* is based on 18 hours with 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.
