  1. 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).

  2. 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.

  3. Charge times are from 0–80% and 0–100% using the included Apple Watch Magnetic Charging Cable. 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, Apple Watch Magnetic Charging USB-C Cable (Model A2652), and Apple 20W USB-C Power Adapter (Model A2305). Charge time varies with settings and environmental factors; actual results will vary.

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

  5. Requires Apple Watch: Series 7, SE, Ultra, or later. For a list of supported countries and regions, see apple.com/watchos/feature-availability.

  6. 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. 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.

  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/HT207578 for additional setup instructions.

  8. Not all features will be available if the Apple Watch is set up through Apple Watch For Your Kids. Wireless service plan required for cellular service. Contact your service provider for more details. Check apple.com/watch/cellular for participating wireless carriers and eligibility.

  9. 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.

  10. Data accurate as of product launch. Product statements are based on U.S. configuration of Apple Watch SE paired with Sport Loop.

  11. Carbon neutral combinations of this product include Apple Watch SE paired with Sport Loop, Milanese Loop, Braided Solo Loop, and Pride Edition Braided Solo Loop.

  12. Product recycled or renewable content is the mass of certified recycled material relative to the overall mass of the device, not including packaging or in-box accessories.

  13. Our manufacturing electricity is sourced from clean electricity, including a mix of supplier and Apple clean energy projects.

  14. 50% of all carbon neutral products by weight are planned, as of product launch, to be shipped via non-air modes of transportation over the lifetime of the products.

  15. Carbon reductions are calculated against a baseline scenario: 1) No use of clean electricity for manufacturing or product use, beyond what is already available on the latest modeled grid (based on regional emissions factors). 2) Apple’s carbon intensity of key materials as of 2015 (our baseline year for our 2030 product carbon neutrality goal). Carbon intensity of materials reflects use of recycled content and production technology. 3) Apple’s average mix of transportation modes (air, rail, ocean, ground) by product line across three years (fiscal years 2017 to 2019) to best capture the baseline transportation emissions of our products.

  16. For more information about our use of carbon credits, please see the Product Environmental Report.

  17. Based on retail packaging as shipped by Apple. Breakdown of U.S. retail packaging by weight. Adhesives, inks, and coatings are excluded from our calculations of plastic content and packaging weight.

  18. Apple is matching 100% of expected electricity consumption only for carbon neutral aluminum Apple Watch Series 10, Apple Watch SE, and Apple Watch Ultra 2 combinations.

  19. Apple Watch SE meets California Energy Commission’s Energy Efficiency Standards for Small Battery Charger Systems as outlined in the California Code of Regulations.

  20. Apple’s Regulated Substances Specification describes Apple’s restrictions on the use of certain chemical substances in materials in Apple products, accessories, manufacturing processes, and packaging used for shipping products to Apple’s end-customers. Restrictions are derived from international laws or directives, regulatory agencies, eco-label requirements, environmental standards, and Apple policies. Every Apple product is free of PVC and phthalates except for AC power cords in India, Thailand (for two-prong AC power cords), and South Korea, where we continue to seek government approval for our PVC and phthalates replacement. Apple products comply with the European Union Directive 2011/65/EU and its amendments, including exemptions for the use of lead such as high-temperature solder. Apple is working to phase out the use of these exempted substances for new products where technically possible.

The ability to measure blood oxygen is no longer available on Apple Watch units sold by Apple in the United States beginning January 18, 2024. These are indicated with part numbers ending in LW/A. Learn how to identify your Apple Watch.

Apple Watch Ultra 2, Apple Watch Series 10, and Apple Watch SE require iPhone Xs or later with iOS 18 or later.
