To factory reset an Apple Watch, you can either unpair it from your iPhone or erase it directly from the watch itself. The right method depends on whether you're troubleshooting a problem or handing the watch to someone else, because only unpairing removes Activation Lock.
How to factory reset an Apple Watch: Two methods for different needs
Before you start, understand why you're resetting. If your Apple Watch is acting up, freezing, crashing, or stuck on an update, a direct erase from the watch is usually enough to clear the issue. But if you're selling or giving away the watch, you must unpair it from your iPhone. That's the only way to fully remove Activation Lock, the security feature that ties the watch to your Apple ID. Without removing it, the next owner won't be able to pair the watch to their iPhone, and you'll have a useless device on your hands.
Also note: an Apple Watch does not have a physical SIM slot or a dedicated reset button. The small holes on the side are for sound and water-depth measurement, not for poking with a paperclip. And a "hard reset", pressing and holding the side button and Digital Crown together, only reboots the watch; it does not erase any data. That's a troubleshooting trick, not a factory reset.
Method 1: Unpair from your iPhone (recommended for selling or giving away)
This is the cleanest way to factory reset your Apple Watch because it simultaneously erases all content, restores factory settings, and disables Activation Lock. It also creates a backup of your watch's data on your iPhone before erasing, so you can restore it later if you change your mind.
- Keep your Apple Watch and iPhone close together throughout the process.
- On your iPhone, open the Apple Watch app.
- Go to the "My Watch" tab, then tap "All Watches."
- Tap the info button (the "i" icon) next to the watch you want to unpair.
- Tap "Unpair Apple Watch."
- Tap "Unpair [your Apple Watch name]" to confirm.
- If your watch has a mobile plan, you'll be asked whether to keep or remove it. Choose "Remove" if you're selling or giving away the watch; choose "Keep" if you're re-pairing it with the same iPhone.
- You may need to enter your Apple Account password to disable Activation Lock. Do this when prompted.
Once you confirm, the unpairing process begins. Your iPhone will erase the watch and remove it from your account. When it's done, the watch will restart and show the setup screen, ready for a new owner.
Method 2: Erase directly on your Apple Watch
If you don't have your iPhone nearby, or you're just troubleshooting and plan to keep the watch, you can erase it directly from the watch itself. This method restores the watch to factory settings, but it does not remove Activation Lock. That means the watch will still be tied to your Apple ID until you unpair it from your iPhone later.
- On your Apple Watch, open the Settings app.
- Tap "General."
- Tap "Reset."
- Tap "Erase All Content and Settings."
- Type your passcode if prompted.
- If your watch has a mobile plan, choose whether to keep or remove it.
- Tap "Erase All" to confirm.
The watch will erase itself and restart. After it reboots, you'll see the setup screen. But remember: until you unpair it from your iPhone, Activation Lock remains active. If you're keeping the watch, that's fine. If you're selling it, you'll still need to unpair it from your iPhone afterward to remove the lock.
What to do if you forgot your passcode
If you can't get past the passcode screen, you can still reset the watch, but you'll need to use a different method. Place the watch on its charger, then press and hold the side button until you see the power button appear on the screen. Next, press and hold the Digital Crown until you see "Erase all content and settings" appear. Tap that to wipe the watch. This bypasses the passcode entirely, but it also means you won't get a backup of your data, the erase happens immediately without creating one.
Set up your Apple Watch after the reset
After the reset completes, your Apple Watch will restart and show the setup screen. Before you begin, note that a backup of your watch's contents is automatically created on your paired iPhone before the erase. To set up the watch again, bring it near your iPhone and follow the on-screen pairing prompts. When asked, choose "Set Up as New Apple Watch" if you want a clean slate, or "Restore from Backup" to pull your data back. If you restore, pick the most recent backup from the list and enter your Apple ID password if prompted. The restoration may take a few minutes, so keep both devices close and connected to Wi-Fi until it finishes. Once done, you can customize your watch faces, install apps, and personalize settings as you like.
