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.
