The case materials and the band types would be based on your selection

1. Emergency SOS requires a cellular connection or Wi-Fi Calling with an internet connection from your Apple Watch or nearby iPhone.

2. Apple Watch Series 8 is rated IP6X dust resistant.

3. Apple Watch Series 8 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 Series 8 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.

4. 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.

5. 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.

6. 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.

7. 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.

8. 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.

9. 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 Series 8 (GPS) usage includes connection to iPhone via Bluetooth during the entire 18-hour test; Apple Watch Series 8 (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 Series 8 (GPS) and Apple Watch Series 8 (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.

10. A portion of the proceeds from every (PRODUCT)RED purchase goes to the Global Fund to fight AIDS and mitigate the impact of COVID-19 with (RED). See apple.com/product-red for more information.

11. Ultra Wideband availability varies by region.

12. Data accurate as of product launch.

13. Meets California Energy Commission’s Energy Efficiency Standards for Small Battery Charger Systems as outlined in the California Code of Regulations.

14. 100% of virgin wood fiber comes from responsibly managed forests and 90% or more of the packaging is fiber-based.

15. Apple defines its restrictions on harmful substances, including definitions for what Apple considers to be “free of,” in the Apple Regulated Substances Specification. Every Apple product is free of PVC and phthalates with the exception of AC power cords in India, Thailand (for 2-prong AC power cords), and South Korea where we continue to seek government approval for our PVC and phthalates replacement.
