Resetting an Apple Watch wipes it back to factory settings — the right move before selling it, handing it on, pairing it with a new iPhone, or clearing a problem a restart won’t fix. There are two ways to do it, and the one you choose affects whether Activation Lock is removed. Here’s exactly how to reset an Apple Watch on watchOS 11, step by step, plus what gets erased versus kept, and the mistakes to avoid.
- Unpairing backs up first — automatically. When you unpair from the iPhone, it makes a fresh backup of the watch before erasing, so you can restore to a new or repaired watch.
- Best method: unpair in the Watch app on your iPhone — it erases the watch and removes Activation Lock.
- On-watch method: Settings > General > Reset > Erase All Content and Settings — handy if the watch isn’t near its iPhone, but it does not remove Activation Lock.
- Erased: all data, settings, and content on the watch. Kept: nothing on the watch itself — but the iPhone backup and your iCloud data are safe.
- Cellular models ask whether to keep or remove the plan — keep it if you’re re-pairing to the same account.
Back up first — this erases the watch. A reset wipes everything on the Apple Watch. The good news: if you unpair through your iPhone, it automatically makes a new backup of the watch right before erasing, which you can restore later. If you erase directly on the watch instead, make sure your iPhone’s own backup is current (iPhone backups include your watch data) so nothing is lost.
The short answer: Open the Watch app on your iPhone, go to My Watch > All Watches, tap the info (i) button next to your watch, and choose Unpair Apple Watch. This backs up, erases, and removes Activation Lock. No iPhone nearby? On the watch, go to Settings > General > Reset > Erase All Content and Settings.
How to reset an Apple Watch: step by step
Use the iPhone method whenever you can — it handles the backup and Activation Lock for you.
- Keep the watch and iPhone close together. Put the two devices near each other and connected so the backup and unpair can complete.
- Open the Watch app on your iPhone. Tap the My Watch tab, then tap All Watches at the top.
- Select your watch. Tap the info (i) button next to the watch you want to reset.
- Tap Unpair Apple Watch. Confirm when asked. For cellular models, choose whether to keep or remove your cellular plan — keep it if you’ll re-pair to the same account.
- Enter your Apple Account password. This turns off Activation Lock. The iPhone then makes a final backup of the watch and erases it. Wait for it to finish.
- (No iPhone available) Erase on the watch. On the watch, open Settings > General > Reset, tap Erase All Content and Settings, and enter your passcode. Note this leaves Activation Lock on.
- Set up or restore. The watch restarts to its pairing screen. Re-pair it to restore from a backup, or leave it ready for a new owner.
| Method | Backs up? | Removes Activation Lock? |
|---|---|---|
| Unpair via iPhone Watch app | Yes, automatically | Yes |
| Erase on the watch (Settings) | No | No — stays locked to your account |
Selling or giving the watch away? Always use the iPhone unpair method so the next owner can set it up.
What this reset does (and what you’ll lose)
A reset returns the Apple Watch to its factory state. Afterward it holds none of your information and must be paired again before it will do anything.
What is erased: all apps and their data, health and activity data stored only on the watch, saved cards in Wallet, messages, custom watch faces, settings, and your passcode. What is kept: nothing stays on the watch — but if you unpaired through the iPhone, the automatic backup restores everything to a new or repaired watch, and health data synced to the iPhone’s Health app and iCloud is safe regardless. The key difference between methods is Activation Lock: unpairing through the iPhone removes it, while erasing on the watch leaves it on, meaning the watch stays tied to your Apple Account and can’t be set up by anyone else.
Common mistakes to avoid
- Erasing on the watch when selling it — this leaves Activation Lock on, so the buyer is locked out. Unpair through the iPhone instead.
- Not confirming the iPhone backup — if you erase directly on the watch, make sure your iPhone backup is current first, or recent watch data may be lost.
- Removing the cellular plan by accident — if you’re re-pairing to the same account, choose “keep” so you don’t have to re-activate the plan with your carrier.
- Moving the devices apart mid-process — keep the watch and iPhone close together until the unpair and backup fully complete.
- Forgetting your Apple Account password — you’ll be stuck at the Activation Lock step. Recover it at account.apple.com beforehand.
Does resetting an Apple Watch remove Activation Lock?
Only if you unpair it through the Watch app on your paired iPhone — that method signs the watch out of your Apple Account and removes Activation Lock. Erasing the watch directly from its own Settings menu wipes the data but leaves Activation Lock in place, so the watch stays tied to your account. Always use the iPhone unpair method before selling or giving the watch away.
How to reset an Apple Watch FAQ
How do I reset an Apple Watch without the paired iPhone?
On the watch, go to Settings > General > Reset > Erase All Content and Settings and enter your passcode. This wipes the watch but leaves Activation Lock on, so you’ll still need your Apple Account credentials to set it up again.
Does unpairing my Apple Watch erase it?
Yes. Unpairing automatically erases the watch and restores it to factory settings — but first your iPhone makes a fresh backup you can restore later.
Will I lose my health and fitness data?
No, as long as it’s synced. Health and activity data lives in the Health app on your iPhone and in iCloud, so it survives the watch reset and reappears when you re-pair.
How do I force restart an Apple Watch instead of resetting it?
Press and hold both the side button and the Digital Crown for about 10 seconds until the Apple logo appears. A force restart fixes many glitches without erasing anything — try it before a full reset.
What happens to my cellular plan when I reset?
Cellular models ask whether to keep or remove the plan. Keep it if you’re re-pairing to the same Apple Account; remove it if you’re giving the watch to someone else.
How often should I reset my Apple Watch?
Rarely. A full reset is for selling, switching iPhones, or fixing serious problems. For everyday slowdowns, a force restart or toggling a setting is usually enough.
Can I restore my watch from a backup after resetting?
Yes. When you re-pair the watch to your iPhone, you’ll be offered the option to restore from a backup, which brings back your apps, faces, and settings.
