When the Apple Watch first launched, we showed you in detail how to pair and set-up the device with your iPhone. Now, we’re going to show you how to unpair your Apple Watch from your iPhone. There are several reasons one might want to unpair the two devices…

The first step in the unpairing process is to ensure that your Apple Watch and iPhone are close enough together to be connected. Then, you’ll want to open the Apple Watch App on your iPhone.
From there, tap “My Watch” tap at the bottom of the interface, then choose the “Apple Watch” panel, as shown in the screenshots above. Then tap the “Unpair Apple Watch” button. The app will ask you to confirm that you wish to unpair the two devices, which will erase all content and settings from the Watch. Your iPhone, however, will make a backup of your Apple Watch before completing the unpairing process. You’ll later be able to restore that backup to a new Apple Watch if you desire.
If you wish to unpair your Apple Watch from your iPhone directly from your wrist as opposed to using the app, you can do so by heading into the Settings app, then choosing General, Reset, and Erase all Content and Settings.
Once the process is complete, you can pair and setup Apple Watch with your iPhone again using these steps.
