To reset and erase an Apple Watch, you have two main options: unpair it from your iPhone (which creates a backup) or erase it directly on the watch itself. This guide walks you through both methods, explains what each one does, and covers common issues like forgotten passcodes and activation locks.
Why You Might Need to Reset
Resetting your Apple Watch is useful in several situations: you’re selling or giving it away, you’ve forgotten your passcode, the watch is behaving erratically, or you want to start fresh with a new iPhone. Unpairing is the preferred method when you still have your iPhone, because it automatically creates a backup of your watch’s data and settings. Erasing directly on the watch is the fallback when you don’t have the paired iPhone available.
Method 1: Unpair from Your iPhone (Recommended)
This is the safest and most complete reset method. It creates a backup, removes Activation Lock, and clears all personal data.
- Keep your Apple Watch and iPhone close together.
- Open the Watch app on your iPhone.
- Tap the “All Watches” tab at the top.
- Tap the info button (i) next to the watch you want to unpair.
- Tap “Unpair Apple Watch.”
- Confirm by tapping “Unpair” again.
If you have a cellular model, you may be asked to keep or remove your cellular plan. After unpairing, the watch will erase itself and return to its setup screen. The backup is stored on your iPhone, so you can restore it later by pairing the watch again.
Method 2: Erase Directly on the Watch
Use this method when you don’t have your iPhone, or if the watch is stuck on the passcode screen. It erases everything without creating a backup.
- Place the watch on its charger.
- Press and hold the side button until you see the Power Off slider.
- Firmly press the slider (or press the Digital Crown) until you see “Erase All Content and Settings.”
- Tap “Erase All Content and Settings” and confirm.
This method also removes Activation Lock, but only if you know your Apple ID and password. If you don’t, the watch will remain locked to your Apple ID until you enter them.
What If You Forgot Your Passcode?
If you can’t enter the passcode, you can’t use the on-watch erase method. Instead, you must first erase the watch through the iPhone Watch app (if it’s still paired) or by putting the watch into recovery mode. To force a factory reset on a passcode-locked watch:
- Place the watch on its charger.
- Press and hold the side button and Digital Crown together for about 10 seconds.
- Release when you see the Apple logo, then wait for the reset to complete.
This method erases the watch without needing the passcode, but it does not remove Activation Lock. You’ll still need your Apple ID and password after the watch restarts.
Activation Lock and Your Apple ID
Activation Lock is a security feature that prevents anyone else from using your watch if it’s lost or stolen. When you unpair via the iPhone, Activation Lock is automatically removed. When you erase directly on the watch, it stays enabled until you sign in with your Apple ID. If you’re selling the watch, you must disable Activation Lock first, or the buyer won’t be able to pair it. To check if Activation Lock is on, go to the Watch app on your iPhone, tap your watch at the top, then tap the info (i) and look for “Activation Lock.”
Common Problems and Solutions
- Watch won’t unpair: Make sure your iPhone is on Wi-Fi or cellular and that Bluetooth is enabled. Restart both devices if needed.
- Erase option not showing: The on-watch erase option only appears when you press and hold the Power Off slider firmly. If it doesn’t appear, try a force restart first.
- Stuck on Apple logo after reset: This can happen if the reset was interrupted. Place the watch on its charger and try a force restart again.
- Activation Lock after erase: You’ll need to enter the Apple ID and password that were used on the watch. If you forgot them, you’ll need to recover your Apple ID through Apple’s website.
- Cellular plan still active: After unpairing, your carrier may keep the plan active. Contact your carrier to remove it if you’re selling the watch.
What Happens to Your Data?
Unpairing creates a backup of your watch’s settings, app layouts, and data (like Activity rings and health data) on your iPhone. Erasing directly on the watch does not create a backup. In both cases, all data on the watch itself is permanently deleted. If you haven’t backed up your iPhone recently, your watch data may be lost. To restore from a backup, pair the watch again and choose “Restore from Backup” when prompted.
When to Use Each Method
- Unpair: Best for selling, trading in, or when you’re moving to a new iPhone. It preserves your data and removes Activation Lock.
- Erase on watch: Use when you don’t have your iPhone, or when the watch is unresponsive. It’s a last resort because it doesn’t back up anything.
- Recovery mode: Only for when you’re locked out by a passcode and can’t use the iPhone method.
Frequently Asked Questions
Will resetting my Apple Watch remove it from my Apple ID?
No, resetting alone does not remove the watch from your Apple ID. You must unpair it via the iPhone (which removes Activation Lock) or sign in with your Apple ID after erasing. If you don’t, the watch remains linked to your account.
Can I reset my Apple Watch without the paired iPhone?
Yes, you can erase it directly on the watch using the side button and Digital Crown method. However, you’ll still need your Apple ID and password to complete the setup if Activation Lock is enabled.
Does unpairing delete my Activity data?
No, unpairing creates a backup that includes your Activity rings, health data, and settings. You can restore this backup when you pair the watch again. If you erase directly on the watch without unpairing, that data is lost unless you have an iPhone backup.
How long does a factory reset take?
Typically 2–5 minutes, depending on the model and how much data is stored. The watch will restart and show the hello screen when done. If it takes longer than 10 minutes, try a force restart.
What should I do before selling my Apple Watch?
Unpair it from your iPhone, remove your cellular plan if applicable, and make sure Activation Lock is off. Then wipe the watch using the on-watch erase method as a final step. This ensures the buyer can pair it without issues.
Can I reset my Apple Watch if I forgot my Apple ID password?
You can erase the watch, but you won’t be able to set it up again without the Apple ID password. You’ll need to recover your Apple ID through Apple’s official password recovery process before the watch becomes usable again.
