Switching to a new iPhone, selling your watch, or starting over with a fresh setup can all leave you with the same task: disconnecting the two devices properly.
How to unpair Apple Watch matters because simply erasing the watch is not always the same as fully removing it from your account. Taking the correct route helps avoid backup, Activation Lock, and pairing problems when the watch is set up again.
1. Before You Unpair Your Apple Watch
A little preparation can prevent problems during the reset and make it easier to set the watch up again later.
- Keep the Apple Watch and paired iPhone close together throughout the process.
- Make sure both devices have enough battery to finish unpairing.
- When you unpair through the paired iPhone, Apple creates a backup of the watch, erases it, restores factory settings, and removes Activation Lock after the required Apple Account authentication.
If you plan to sell or give the watch away, unpairing from the paired iPhone is preferable to simply erasing the watch because erasing it directly does not remove Activation Lock.
2. How to Unpair Apple Watch Using Your iPhone (Recommended)
The standard method for how to unpair Apple Watch from iPhone is through the Watch app. Apple recommends keeping the two devices close together while the process completes.
Step 1: Keep Your Apple Watch and iPhone Close Together
Place the Apple Watch next to the iPhone it is currently paired with.
Avoid moving either device away or turning them off until unpairing finishes.
Step 2: Open the Watch App
On your iPhone, open the Apple Watch app and go to the My Watch tab.
Tap All Watches at the top of the screen.
Step 3: Select Your Apple Watch
Find the watch you want to disconnect and tap the info button (i) beside it.
Make sure you choose the correct watch if more than one Apple Watch appears in the app.
Step 4: Tap Unpair Apple Watch
Tap Unpair Apple Watch, then confirm the action.
For a cellular model, Apple may ask whether you want to keep or remove the cellular plan. Keep it if you plan to pair the watch again yourself; remove it if you are selling or giving the watch away.
This is also the preferred approach for how to unpair Apple Watch from old phone when you still have access to that paired iPhone.
Step 5: Enter Your Apple Account Password
Enter the password for the Apple Account associated with the watch when prompted.
This disables Activation Lock as part of the unpairing process, allowing the watch to be paired with another iPhone later.
Step 6: Wait for the Unpairing Process to Finish
Let the iPhone and Apple Watch remain close together until the process completes.
The iPhone creates a current backup of the watch before erasing it. Once finished, the Apple Watch returns to its factory setup state and can be paired again or prepared for a new owner.

3. How to Unpair Apple Watch Without iPhone
If the paired iPhone is lost, unavailable, or no longer accessible, you can erase the watch directly. However, this is an important distinction: erasing the watch without the paired iPhone does not remove Activation Lock.
Erase the Apple Watch from Settings
For how to unpair an Apple Watch when you do not have the paired iPhone:
- Open Settings on the Apple Watch.
- Go to General > Reset.
- Tap Erase All Content and Settings.
- Enter the watch passcode if requested.
- Follow the prompts to complete the reset.
The watch’s data and settings will be erased, but the device remains associated with the Apple Account that previously enabled Activation Lock.
What Happens to Activation Lock?
Activation Lock remains enabled when you erase the watch directly instead of unpairing it through the paired iPhone.
That means the Apple Account credentials associated with the watch may still be required before it can be activated with another iPhone. Apple specifically notes that erasing all content and settings does not remove Activation Lock.
What You’ll Need to Do Before Pairing Again
If the watch still belongs to you, sign in with the Apple Account previously associated with it when prompted during setup.
If you are preparing the watch for another owner and no longer have the old iPhone, remove Activation Lock through your Apple Account before handing it over. Apple provides a web option through Find My for eligible devices.
Simply erasing the watch is therefore enough for a personal reset, but not enough by itself when ownership is changing.
4. What Happens When You Unpair an Apple Watch?
When you unpair through the paired iPhone, several things happen automatically. Your iPhone creates a current Apple Watch backup before erasing the watch, so supported settings and data can be restored later. The watch is then returned to factory settings.
Activation Lock is also removed as part of the proper unpairing process after you provide the required Apple Account password. This is an important difference between unpairing through the Watch app and simply erasing the Apple Watch directly.
Apple explains the backup, erasure, and Activation Lock process in its official unpairing instructions.
5. What to Do If You Can’t Unpair Your Apple Watch
Problems with how to unpair Apple Watch usually depend on whether you still have access to the paired iPhone and Apple Account. Match the problem to the appropriate next step:
- Apple Watch won’t unpair: Keep both devices close together, make sure they have sufficient battery, and restart them before trying again. If the paired iPhone is unavailable, you can erase the watch directly, but this does not remove Activation Lock.
- Forgot your Apple Account password: Reset the password through Apple’s account-recovery options before attempting to remove Activation Lock.
- iPhone is lost or no longer available: Erase the Apple Watch from the watch itself. If you are selling or giving it away, you will also need to remove it from your Apple Account so Activation Lock does not remain attached.
- Activation Lock is still enabled: Sign in with the Apple Account originally associated with the watch and remove the device from your account. Resetting or erasing the watch alone does not bypass Activation Lock.
6. Before You Sell, Trade In, or Give Away Your Apple Watch
Preparing a watch for someone else requires more than simply deleting your personal data. Use this checklist alongside the steps for how to unpair Apple Watch:
- Back up your watch: Unpair through the paired iPhone when possible so it can create a current backup before erasing the device.
- Unpair it from your iPhone: Use the Watch app rather than relying only on a factory reset.
- Remove Activation Lock: Confirm that the watch is no longer locked to your Apple Account before handing it over.
- Erase personal content and settings: Proper unpairing handles this automatically. If you erase manually, remember that Activation Lock can remain.
- Handle the cellular plan: For cellular models, remove or cancel the plan when appropriate. You may need to contact your carrier if you are ending the service.
- Clean the watch and accessories: Follow Apple’s cleaning recommendations and gather any bands, chargers, or accessories you plan to include.
