  1. The temperature sensing feature is not intended for medical use.

  2. ECG app is available on Apple Watch Series 4 and later (excluding Apple Watch SE) and can generate an ECG similar to a single-lead electrocardiogram. Intended for use by people 22 years old and over.

  3. Cycle Tracking app should not be used for birth control or to diagnose a health condition.

  4. 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 (AF).

  5. All‑day battery life is based on the following use: 180 time checks, 180 notifications, 90 minutes of app use and a 60‑minute workout with music playback from Apple Watch via Bluetooth, over the course of 36 hours; Apple Watch Ultra 2 (GPS + Cellular) usage includes a total of 8 hours of 4G LTE connection and 28 hours of connection to iPhone via Bluetooth over the course of 36 hours. Battery life in Low Power Mode is based on the following use: 360 time checks, 360 notifications, 180 minutes of app use and two 60‑minute workouts with music playback from Apple Watch via Bluetooth, over the course of 72 hours; Apple Watch Ultra 2 (GPS + Cellular) usage includes on‑demand 4G LTE connection and 60 hours of connection to iPhone via Bluetooth over the course of 72 hours. Testing conducted by Apple in August 2023 using pre‑production Apple Watch Ultra 2 (GPS + Cellular) paired with an iPhone; all devices tested with pre‑release software. Battery life varies by use, configuration, mobile network, signal strength and many other factors; actual results will vary.

  6. Charge times are from 0–80% and 0–100% using the included Apple Watch Magnetic Fast Charging USB‑C Cable. Testing conducted by Apple in August 2023 using pre‑production Apple Watch Ultra 2 (GPS + Cellular) paired with an iPhone; all devices tested with pre-release software, Apple Watch Magnetic Fast Charging USB‑C Cable (Model A2515) and Apple 20W USB‑C Power Adapter (Model A2305). Charge time varies with region, settings and environmental factors; actual results will vary.

  7. A subscription is required for Oceanic+. Available on the App Store. Always follow diving protocols, and dive with a companion and have a secondary device.

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

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

  10. Apple Watch Ultra 2 has a water resistance rating of 100 metres under ISO standard 22810. It may be used for recreational scuba diving (with compatible third-party app from the App Store) to 40 metres and high-speed water sports. Apple Watch Ultra 2 should not be used for diving below 40 metres. Water resistance is not a permanent condition and can diminish over time. For additional information, see support.apple.com/en-gb/109522.

  11. Apple Watch Ultra 2 is rated IP6X dust resistant.

  12. Wireless service plan required for cellular service. Contact your service provider for more details. Connection may vary based on network availability. Check apple.com/uk/watch/cellular for participating network providers and eligibility. See support.apple.com/en‑gb/HT207578 for additional setup instructions.

  13. Ultra Wideband availability varies by region.

  14. Not all features will be available if the Apple Watch is set up through Family Setup. Wireless service plan required for cellular service. Contact your service provider for more details. Check apple.com/uk/watch/cellular for participating network providers and eligibility.

  15. Data accurate as of product launch. Product statements are based on US configuration of Apple Watch Ultra 2 paired with Alpine Loop.

  16. 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.

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

  18. 50% of all carbon-neutral products by weight are planned, as of product launch, to be shipped via non-air modes of transport over the lifetime of the products.

  19. 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 modelled 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 transport modes (air, rail, sea, land) by product line across three years (fiscal years 2017 to 2019) to best capture the baseline transport emissions of our products.

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

  21. All cobalt claims are on a mass balance allocation.

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

  23. Apple is matching 100% of expected electricity consumption only for carbon-neutral aluminium Apple Watch Series 9, Apple Watch SE and Apple Watch Ultra 2 combinations.

  24. Apple Watch Ultra 2 meets California Energy Commission’s Energy Efficiency Standards for Small Battery Charger Systems as outlined in the California Code of Regulations.

  25. 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 leads in India, Thailand (for two-pin AC power leads) and the Republic of 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.

Apple Watch Ultra 2, Apple Watch Series 9 and Apple Watch SE require iPhone Xs or later with iOS 17 or later.
