To move a watch to a new iPhone, use the transfer prompt when setting up the new phone; if that fails, unpair from the old iPhone to create a watch backup before pairing again. If the old iPhone is unavailable, you can erase the watch, but Activation Lock still requires the Apple Account previously used with it.
Check compatibility and get ready
Apple Watch requires an iPhone; it cannot pair with an iPad, Mac, or Android phone. Requirements vary by watch model, so identify your watch and check Apple’s Apple Watch and iPhone compatibility table before troubleshooting. For example, Series 11, SE 3, and Ultra 3 require an iPhone 11 or later with iOS 26 or later. Apple’s setup guide is the reference for current setup requirements.
| Watch models | Minimum iPhone and iOS |
|---|---|
| Series 11, SE 3, Ultra 3 | iPhone 11 or later; iOS 26 or later |
| Series 10 | iPhone XS or later; iOS 18 or later |
| Series 9, Ultra 2 | iPhone XS or later; iOS 17 or later |
| Older models | Requirements vary; check Apple’s compatibility table |
Install the newest software available for both devices before starting. To identify a watch, open the Watch app on a paired iPhone and go to My Watch > General > About; Apple also explains how to identify your Apple Watch.
- Have the Apple Account email or phone number and password. For an existing watch, know its passcode too.
- Enable Bluetooth and connect the iPhone to Wi-Fi or cellular.
- Keep the devices nearby. For a transfer to a new iPhone, Apple recommends at least 50% charge on both devices.
- Allow time for software updates and syncing to finish.
Pair an Apple Watch for the first time
- Turn on the watch by holding its side button until the Apple logo appears.
- Unlock the iPhone and bring it close to the watch. Tap Continue when the setup prompt appears, then tap Set Up for Myself.
- Center the animation on the watch in the iPhone camera viewfinder.
- Choose Set Up as New Apple Watch or restore a backup if one is available, then follow the prompts for wrist, Apple Account, passcode, health and safety settings, and other options.
- Keep the devices close while setup and syncing finish.
You can skip setting a passcode, but Apple Pay requires one. If the prompt does not appear, open the Watch app and tap All Watches > Add Watch. If the camera cannot read the animation, choose Pair Apple Watch Manually and enter the code shown on the watch. See Apple’s setup instructions.

Move an existing Apple Watch to a new iPhone
The easiest option is to transfer the watch as part of setting up the new iPhone. Update the old iPhone and watch, make a current iPhone backup, then set up the new iPhone from that backup or use the normal iPhone transfer process. When prompted to use the watch, keep it unlocked and on your wrist near the new iPhone, then continue. Follow Apple’s new-iPhone transfer guide.
- Before migration, check that Health is enabled in iCloud: Settings > [your name] > iCloud > See All > Health.
- Make a current iPhone backup. If backing up to a computer, use an encrypted backup to preserve Health and Activity data.
- Set up the new iPhone from the backup or by using device transfer, then accept the prompt to transfer the watch.
- If transfer is incomplete, open the Watch app on the new iPhone, go to My Watch > All Watches, and tap Pairing Not Complete or Finish Pairing if shown.
If the new iPhone shows Start Pairing instead, the watch may still be associated with the old iPhone. If you can access it, unpair there first, then pair on the new iPhone and select the newest watch backup. Apple provides transfer troubleshooting steps.
Manual unpair and restore
Use this route if automatic transfer fails or the new iPhone is already set up. Unpairing from the old iPhone erases the watch, removes Activation Lock, and creates a watch backup first.
- On the old iPhone, open the Watch app and tap My Watch > All Watches.
- Tap the information button next to the watch, then Unpair Apple Watch and confirm. Enter the Apple Account password when asked.
- For a cellular watch you will keep using, choose to keep the plan. Remove it only if you are selling or giving away the watch or canceling service.
- On the new iPhone, open the Watch app and tap All Watches > Add Watch. Pair the watch and choose the latest backup offered.

If the old iPhone is unavailable
- On the watch, open Settings > General > Reset > Erase All Content and Settings.
- Pair the erased watch with the new iPhone and restore a backup if offered; otherwise choose Set Up as New Apple Watch.
- Enter the Apple Account credentials previously used with the watch if Activation Lock appears.
Erasing directly does not remove Activation Lock. Without a usable backup, set up as new; Apple says Health and Activity content cannot be recovered if no usable backup or sync exists. See Apple’s pairing troubleshooting guide.
What transfers in an Apple Watch backup?
Watch data is backed up automatically to the paired iPhone when the devices are near each other. An iPhone iCloud or computer backup includes Apple Watch data, and unpairing creates a current watch backup before erasing. Health and Fitness data requires iCloud syncing or an encrypted computer backup. Apple details what Apple Watch backups include.
| Generally included | Not included in the watch backup |
|---|---|
| App settings, watch-face settings and order, app layout, notifications, brightness, sound, haptics, and time zone | Bluetooth pairings, Apple Pay cards, and the watch passcode |
| Health and Fitness data, history, awards, calibration data, and user-entered data, when backed up appropriately | Information already synced to iCloud, such as Voice Memos, and Messages |
| Synced music and the selected photo album | Some third-party app data, depending on how the app stores or syncs it |
Apple Pay cards and Bluetooth accessories need to be set up again. Health and Activity data may take time to reappear after signing in to the same Apple Account. Activity Sharing data is not stored in iCloud. If the old iPhone is gone and no usable backup exists, that data may be unrecoverable.
Activation Lock, used watches, and cellular plans
Activation Lock links a watch to the Apple Account used with Find My. A used watch must be unpaired by its previous owner and removed from that account; erasing it alone is not enough. If setup requests the previous owner’s account, ask them to remove the lock. There is no legitimate setup workaround. Read Apple’s Activation Lock guidance and what to do before buying or selling a watch.

Cellular service depends on the watch model, carrier, account, and region. For a personal watch, the iPhone and watch generally need the same carrier, and some prepaid, corporate, or older plans may not be eligible. To activate later, use Watch app > My Watch > Cellular > Set Up Cellular. Removing a plan may not cancel the carrier subscription. See Apple’s cellular setup guide.

FAQ
Can I pair an Apple Watch with Android?
No. Apple Watch pairs with a compatible iPhone, not an Android phone, iPad, or Mac.
Can I pair a watch without the old iPhone?
Yes. Erase it from Settings > General > Reset, then pair it with the new iPhone. You still need the Apple Account credentials tied to Activation Lock, and a backup is needed to restore prior watch data.
Will unpairing erase my Health and Activity history?
Unpairing creates a watch backup first. Health and Activity data is preserved when iCloud Health syncing is enabled or the iPhone backup is encrypted. If the old iPhone is unavailable and no usable backup exists, the data may not be recoverable.
Do Apple Pay cards and Bluetooth accessories transfer?
No. Add Apple Pay cards and pair Bluetooth accessories again after setup.
Crashes, No Sound, or Screen Glitches?
