Apple Watch Series 7 requires an iPhone 6s or later with iOS 15 or later. 

Blood Oxygen app measurements are not intended for medical use, including self-diagnosis or consultation with a doctor, and are only designed for general fitness and wellness purposes.
The ECG app is available on Apple Watch Series 4 and later (not including Apple Watch SE) with the latest versions of iOS and watchOS.

Apple Watch Series 7, Apple Watch SE, and Apple Watch Series 3 have a water resistance rating of 50 meters under ISO standard 22810:2010. This means that they may be used for shallow-water activities like swimming in a pool or ocean.

However, they should not be used for scuba diving, waterskiing, or other activities involving high-velocity water or submersion below shallow depth. Series 7 is also rated IP6X dust resistant.
Irregular rhythm notification requires the latest versions 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).
