The fastest way to reconnect your watch
When you get a new iPhone, your old Apple Watch will not automatically connect to it. You need to unpair the watch from your old phone first, then pair it fresh to the new one. The whole process takes about ten minutes if you follow the steps in order, and most of the time is just waiting for the watch to restart.
The key thing to know upfront: your watch will erase during unpairing. This sounds worse than it is. Your watch data backs up to iCloud automatically, so when you pair it to the new iPhone, everything restores — your apps, your activity rings, your settings. You do not lose anything permanent.
Key Takeaways
- You must unpair the watch from your old iPhone before pairing it to a new one, even if you no longer have the old phone nearby.
- Unpairing erases the watch, but your data restores from iCloud backup when you pair to the new iPhone.
- If you cannot access your old iPhone, you can unpair remotely through iCloud.com on any computer or phone.
- The pairing process itself happens through the Watch app on your new iPhone, not on the watch itself.
- After pairing completes, your watch will restart and restore your apps and settings automatically over the next few minutes.
Unpair the watch from your old iPhone
Open the Watch app on your old iPhone. Tap the My Watch tab at the bottom, then tap the watch name at the top of the screen. Tap the information icon (the small circle with an "i" in it) next to your watch name. Scroll down and tap Unpair Apple Watch. You will see a warning that this will erase the watch — that is normal and expected. Tap Unpair again to confirm.
The watch will begin erasing. This takes a few minutes. You will see a progress circle on the watch screen. Do not interrupt it or close the Watch app on your phone. Let it finish completely. Once the watch restarts and shows the Apple logo, the unpair is done.
If you no longer have your old iPhone, or it is broken or lost, you can unpair remotely. Go to iCloud.com on any computer or phone, sign in with the Apple ID that was on your old phone, click Find My, then Devices. Select your watch from the list, click Remove, then Remove again. This unpairs it without needing the old phone in your hands.
Prepare your new iPhone for pairing
Turn on your new iPhone and complete the setup process. You can restore from a backup of your old iPhone, or set it up as new — either way works fine for watch pairing. Make sure you sign in with the same Apple ID you used on your old phone. Your watch data is tied to that Apple ID, so using the same account is what lets your watch restore everything when you pair.
Keep your new iPhone and old watch close together — within a few feet — during the pairing process. Bluetooth works best at short range, and the watch needs to connect to your phone's Wi-Fi network too, so proximity matters.
Pair the watch to your new iPhone
Open the Watch app on your new iPhone. Tap Start Pairing. Point your new iPhone's camera at the watch face. The app will scan the watch automatically. If the camera does not pick it up, tap Pair Apple Watch Manually instead and enter your watch model and size by hand.
Once the app recognizes your watch, it will ask which wrist you wear it on and whether you want to use Siri. Choose your settings. Then tap Continue. The app will begin pairing, and you will see a progress circle on both the watch and the phone. This step takes a few minutes. Keep the devices close and do not put them down or move away from each other.
When pairing finishes, the watch will restart. You will see the Apple logo, then the watch face will appear. At this point, pairing is complete, but your apps and settings are still restoring in the background. This can take five to fifteen minutes depending on how many apps you had. You can use the watch while it restores, but some apps may not open until the restore finishes.
What to do if pairing fails or gets stuck
If the pairing process stops or shows an error, the most common fix is to restart both devices. Restart your iPhone by holding the side button and either volume button, then sliding to power off. Wait ten seconds, then turn it back on. On your watch, hold the side button until you see Power Off, swipe right, then hold the side button again until the Apple logo appears.
Once both devices have restarted, open the Watch app again and try pairing from the beginning. If you get the same error a second time, unpair the watch again (using the steps above), restart both devices, and try pairing once more. Most pairing failures clear up after a full restart cycle.
If your watch is very old — more than five or six years — it may not support your new iPhone's version of watchOS. Check Apple's support page for your specific watch model to see the newest iPhone it can pair with. Older watches sometimes cannot pair with much newer iPhones due to software incompatibility.
Restore your apps and settings after pairing
Once the watch finishes restarting, your apps, activity data, and most settings will restore automatically from iCloud. You do not need to do anything — just wait. The Watch app on your iPhone will show a progress indicator while the restore happens. Some apps may take longer than others to read and install.
A few settings do not restore automatically and you may need to set them again: cellular plan information (if your watch has cellular), payment cards in Apple Pay, and passwords for apps that require them. The watch will prompt you for these as you open each app for the first time.
If you had a custom watch face with complications (the small widgets on your face), those restore too. However, if a complication relied on an app that is no longer available in the App Store, that complication will show a blank space instead. You can edit the watch face to remove it or replace it with a different complication.
Verify your watch is working correctly
Once pairing and restore are complete, test a few basic functions to make sure everything connected properly. Raise your wrist and check that the watch face appears. Open the Stocks app or Weather app on the watch — these require an internet connection, so if they load, your watch is connected to your iPhone's network. Try sending a message from the watch to confirm Bluetooth is working.
Check the Watch app on your iPhone and tap My Watch, then General. You should see your watch listed at the top with a green dot next to it, meaning it is connected. If the dot is gray, the watch and phone are not paired yet or the connection dropped. Try unpairing and pairing again.
If you have a cellular watch, test that cellular works by turning off your iPhone's Bluetooth (not airplane mode), then opening an app on the watch that needs internet. If the app loads, your cellular connection is active. If it does not, contact your carrier to confirm your cellular plan is active on the watch.
Frequently Asked Questions
Do I lose my activity data and rings when I unpair?
No. Your activity history, closed rings, and workout data all back up to iCloud automatically. When you pair the watch to your new iPhone, this data restores within a few minutes. You will not see a gap in your activity history.
Can I pair my old watch to a new iPhone without unpairing from the old phone first?
No. The watch can only be paired to one iPhone at a time. If you try to pair without unpairing first, the pairing will fail. You must unpair from the old phone (or unpair remotely through iCloud if you do not have the old phone) before the watch will pair to a new one.
What if my old iPhone is lost or broken?
You can unpair remotely through iCloud.com. Sign in with your Apple ID, go to Find My, select Devices, find your watch, and click Remove. This unpairs the watch without needing the old phone. After that, pair normally to your new iPhone.
How long does the whole process take?
Unpairing takes about five minutes. Pairing takes about three to five minutes. Restoring your apps and data takes five to fifteen minutes depending on how many apps you had. Total time is usually ten to twenty minutes from start to finish.
Will my watch work with my new iPhone right away after pairing?
Yes, the watch works when ready after pairing completes and it restarts. However, some apps may not open until the restore finishes in the background. Give it ten to fifteen minutes for everything to settle before you assume something is wrong.
