AppleWatchSE has a water resistance rating of 50metres under ISO standard 22810:2010. This means that it may be used for shallow-water activities like swimming in a pool or ocean. AppleWatchSE should not be used for scuba diving or 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-au/HT205000. Case and band combinations can be made within collections (Apple Watch and Apple Watch Hermès) only.

Charge times are from 0–80 per cent and 0–100 per cent using the included Apple Watch Magnetic Fast Charging USB-C Cable. Testing conducted by Apple in August 2023 using preproduction Apple Watch Ultra 2 (GPS + Cellular) paired with an iPhone; all devices tested with prerelease 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. On-device processing is private and secure, and now Siri can be used to access data from the Health app for health- and fitness-related queries. For example, a user can ask how many hours of sleep they had the previous night, for progress on closing their Activity rings, or about their blood glucose level if they have a connected monitor. Users can also make Siri requests on Apple Watch Series 9 to log health data such as their weight, period, or medications taken. 2 ECG app is available on AppleWatch Series4 and later (not including AppleWatchSE) with the latest version of iOS and watchOS. See apple.com/au/watch for compatibility details. ECG is not intended for use by people under 22years old. With the ECG app, AppleWatch is capable of generating an ECG similar to a single-lead electrocardiogram. Emergency SOS requires a cellular connection or Wi‑Fi calling with an internet connection from your Apple Watch or nearby iPhone. 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.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 preproduction Apple Watch Ultra 2 (GPS + Cellular) paired with an iPhone; all devices tested with prerelease 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. The temperature sensing feature is not a medical device and not intended for use in medical diagnosis, treatment or for any other medicalpurpose. Charge times are from 0–80 per cent and 0–100 per cent using the included Apple Watch Magnetic Fast Charging USB-C Cable. Testing conducted by Apple in August 2023 using preproduction Apple Watch Series 9 (GPS) and Apple Watch Series 9 (GPS + Cellular), each paired with an iPhone; all devices tested with prerelease 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. watchOS 10 will be available for Apple Watch Series 4 and later on Monday, September 18, and requires iPhone X S or later running iOS 17. Not all features are available on all devices and in all regions.

Requires an iPhone and Apple Watch with second-generation Ultra Wideband chip. Ultra Wideband availability varies by region.

Emergency SOS requires Wi‑Fi calling with an internet connection from your Apple Watch or nearby iPhone. Case and strap combinations can be made within collections (Apple Watch and Apple Watch Hermès) only. Apple worked with Nike and Hermès on more environmentally friendly band collections. The Nike Sport Band now contains 32 percent or more recycled fluoroelastomer, including colorful flakes made from excess bands that create a randomized pattern, making each band unique, while the Nike Sport Loop with a space-dye pattern repurposes yarn from previous seasons. 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 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.
