Unpairing an Apple Watch is the correct way to erase it before selling, giving it away, sending it for repair, or moving to a new iPhone. It is not the same as a factory reset, and the difference matters: unpairing backs up your data, erases the watch and removes Activation Lock in one process. A factory reset does only the middle part.

Quick answer: how do I unpair an Apple Watch?

  1. Keep the watch and iPhone close together
  2. Open the Watch app on your iPhone
  3. Tap All Watches at the top of the screen
  4. Tap the info button next to your watch
  5. Tap Unpair Apple Watch
  6. On cellular models, choose whether to keep or remove your mobile plan
  7. Enter your Apple Account password to switch off Activation Lock
  8. Wait for it to finish before separating the devices

That password prompt is the step that actually matters. It releases the watch from your account, and skipping it is the most common reason a sold watch cannot be paired by its new owner.

What unpairing actually does

Three things happen in sequence, automatically.

  1. It takes a fresh backup. Before erasing anything, your iPhone syncs a current backup of the watch. This is why unpairing is safer than wiping the watch directly.
  2. It erases the watch. All content and settings are removed and the watch returns to its out-of-box state.
  3. It removes Activation Lock. Entering your Apple Account password releases the watch so somebody else can set it up.

A factory reset performed on the watch itself does only step two. That distinction catches people out constantly.

Unpair, reset or erase: what is the difference?

  • Force restart – erases nothing. For a frozen watch only.
  • Reset settings – returns settings to default but keeps apps and data.
  • Erase all content and settings – wipes the watch but leaves Activation Lock in place. Use when you have no access to the paired iPhone.
  • Unpair – backs up, erases and removes Activation Lock. The right choice in almost every case where you still have the iPhone.

Our guide to resetting an Apple Watch covers the other three methods in detail.

How to unpair without the iPhone

If the paired iPhone has been sold, lost, broken or already wiped, you cannot use the Watch app. You need two separate steps, and doing only one leaves the job half done.

Step one – erase the watch. On the watch, go to Settings, General, Reset, Erase All Content and Settings. Enter the passcode if prompted and confirm.

Step two – remove Activation Lock. On any computer, sign in to iCloud with the Apple Account the watch was paired to. Open Find My, select the watch, and choose Remove This Device.

Without step two the watch is erased but still locked to your account, and nobody else can pair it. This is exactly the situation second-hand buyers most often find themselves in.

How to unpair when the watch screen is broken

You do not need a working watch screen. Unpairing is driven entirely from the iPhone, so a cracked, black or unresponsive display does not prevent it.

Follow the standard steps in the Watch app. As long as the watch powers on and stays within Bluetooth range, the iPhone completes the backup, erase and Activation Lock removal without you touching the watch.

If the watch will not power on, the iPhone cannot reach it. Remove the device through Find My on iCloud instead, which releases Activation Lock even though the watch was never erased. Worth doing before sending a watch for repair or trade-in.

If the screen is the actual problem, we cover Apple Watch screen repair across every generation. A screen lifting at one edge is very often a swollen battery pushing it out rather than glass damage.

Should I keep or remove my cellular plan?

On GPS + Cellular models you are asked this during unpairing, and the right answer depends on what happens next.

  • Keep the plan if you are re-pairing to the same iPhone, sending the watch for repair, or upgrading your phone but keeping the watch and network.
  • Remove the plan if you are selling or giving the watch away, or switching network.

If you remove it and later need it back, you will have to re-add it through your network, which sometimes means a phone call. If in doubt and the watch is staying yours, keep it.

What happens to my data and backups?

Unpairing creates a fresh backup on your iPhone automatically. When you pair a watch again – the same one or a replacement – you are offered the option to restore from it.

What comes back: watch faces, app layout and settings, notification preferences, health and activity data, workout history and general configuration.

What does not: Bluetooth pairings, Apple Pay cards (removed for security and re-added manually), and Messages, which sync from the iPhone rather than the backup.

Health and fitness history lives in the Health app on your iPhone rather than solely on the watch, so it survives independently. The exception is a watch that has not synced recently – open the Watch app and let it sync first, particularly if the watch has been off or out of range.

Unpairing before you sell: a checklist

  1. Sync first. Keep the watch near the iPhone so the backup is current.
  2. Unpair through the Watch app rather than resetting the watch itself.
  3. Remove the cellular plan if the watch is leaving you.
  4. Enter your Apple Account password when prompted. Do not skip this.
  5. Check Find My afterwards and confirm the watch has gone from your device list.
  6. Keep your bands if you want them, and clean the contacts.

Step five takes thirty seconds and is the difference between a smooth sale and a buyer who cannot use what they bought.

Unpairing to move to a new iPhone

You usually do not need to unpair at all. If you set up the new iPhone from a backup of the old one, the watch transfers across automatically.

Unpair only if you are setting the new iPhone up as new rather than from a backup, or if the transfer fails. In that case unpair from the old iPhone first if you still have it, then pair to the new one and restore from the backup. If the old iPhone is gone, use the without-the-iPhone method above.

Common problems while unpairing

Unpairing is stuck or spinning. A backup runs first, so several minutes is normal. Keep both devices close and charged and leave it alone. If nothing has changed after 30 minutes, force restart the watch by holding the side button and Digital Crown for 10 seconds, then try again.

The watch is not listed in the Watch app. Check Bluetooth is on and the devices are in range. Restarting both usually restores the connection.

It asks for a password you do not remember. That is your Apple Account password, not the watch passcode. Reset it through Apple account recovery, then try again.

It says unpairing failed. Try again with Wi-Fi on, since Activation Lock removal needs an internet connection to reach Apple’s servers.

The watch still appears in Find My. Remove it manually there. The entry occasionally lingers even when unpairing completed.

What unpairing will not fix

Unpairing is housekeeping, not a repair. If the watch has a hardware fault, erasing it changes nothing:

A reliable rule: if the watch behaves the same after a full erase and fresh setup, the problem is hardware.

Unpairing works identically across every generation, though older models take longer to back up and erase. If you need a repair rather than a reset:

Frequently asked questions

How do I unpair my Apple Watch from my iPhone?

Open the Watch app on your iPhone, tap All Watches, tap the info button beside your watch, then tap Unpair Apple Watch. Enter your Apple Account password when prompted to remove Activation Lock, and keep both devices close until it finishes. This backs up, erases and releases the watch in one process.

Does unpairing an Apple Watch erase everything?

Yes, the watch is wiped completely – but a fresh backup is taken to your iPhone first, so nothing is truly lost. Pairing a watch again lets you restore that backup, bringing back watch faces, settings, health data and workout history.

How do I unpair an Apple Watch without the iPhone?

Erase the watch via Settings, General, Reset, Erase All Content and Settings. Then separately sign in to iCloud on a computer, open Find My, select the watch and choose Remove This Device. Both steps are needed – the first erases it, the second removes Activation Lock.

Can I unpair an Apple Watch with a broken screen?

Yes. Unpairing runs entirely from the iPhone, so a cracked or unresponsive display does not prevent it, provided the watch powers on and stays in Bluetooth range. If it will not power on, remove it through Find My on iCloud instead.

What is the difference between unpairing and resetting an Apple Watch?

Unpairing backs up your data, erases the watch and removes Activation Lock. A factory reset on the watch only erases it – Activation Lock stays, so the watch remains tied to your Apple Account and nobody else can pair it. Always unpair if you still have the iPhone.

Should I keep or remove my cellular plan when unpairing?

Keep it if you are re-pairing to the same iPhone, sending the watch for repair, or upgrading your phone but keeping the watch. Remove it if you are selling or giving the watch away, or changing network. Re-adding a removed plan sometimes requires contacting your network.

Do I need to unpair before getting a new iPhone?

Usually not. If you set up the new iPhone from a backup of the old one, the watch transfers automatically. Only unpair if you are setting the new phone up as new, or if the automatic transfer fails.

Why is my Apple Watch stuck while unpairing?

A backup runs before the erase, so several minutes is normal. Keep both devices close and charged and leave it alone. If nothing changes after 30 minutes, force restart the watch by holding the side button and Digital Crown for 10 seconds, then try again with Wi-Fi enabled.

Does unpairing remove Activation Lock?

Yes, provided you enter your Apple Account password when prompted. Afterwards, check the watch no longer appears in Find My – if it does, remove it there manually.
