Dust resistance: Apple Watch Series 8, Apple Watch Ultra and Apple Watch Series 7 are rated IP6x dust-resistant.
MIL-STD: Tested against subsections for Altitude, High Temperature, Low Temperature, Temperature Shock, Immersion, Freeze/Thaw, Shock and Vibration.
Water Resistance: Apple Watch Series 8 and Apple Watch SE (2nd generation) have a water-resistance rating of 50 metres under ISO standard 22810:2010. This means that they may be used for shallow-water activities like swimming in a pool or ocean. However, Apple Watch Series 8 and Apple Watch SE (2nd generation) 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-ca/HT205000. Apple Watch Ultra 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 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-ca/HT205000.
Oceanic+ App: 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.

ECG App: The ECG app is available on Apple Watch Series 4 and later (not including Apple Watch SE) with the latest version of iOS and watchOS. See apple.com/ca/watch for compatibility details. ECG is not intended for use by people under 22 years old. With the ECG app, Apple Watch is capable of generating an ECG similar to a single-lead electrocardiogram.
IRN (irregular rhythm notification): 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).

Cycle Tracking: The Cycle Tracking app is not intended for use in medical diagnosis, treatment, or any other medical purpose, including as a form of birth control or to support conception.
Emergency SOS + Crash Detection: Apple Watch Series 4 and later can use a cellular connection for Emergency SOS.
