Set up and pair Apple Watch with iPhone
To use your Apple Watch Series 1 or later with watchOS 5, you need to pair it with an iPhone 5s or later with iOS 12 or later—Apple Watch models with cellular require an iPhone 6 or later. Setup assistants on your iPhone and Apple Watch work together to help you pair and set up your Apple Watch.
WARNING: To avoid injury, read Important safety information for Apple Watch before using your Apple Watch.
