How Do You Reset an Apple Watch, With or Without the Passcode?

This article summarizes general guidance based on Apple's official support documentation for informational purposes. Always back up anything you want to keep before resetting, since the process erases your watch's content and settings.

Key Takeaways

There are two distinct Apple Watch reset scenarios: resetting a watch you can currently unlock (to sell it, fix a software issue, or start fresh), and resetting one where you've forgotten the passcode and need to regain access.
The recommended method when you still have your paired iPhone is unpairing through the Watch app — this both erases the Apple Watch and automatically removes Activation Lock, something a reset done directly on the watch alone does not do.
If you've forgotten your passcode, the watch must be placed on its charger before resetting; the process can't be completed with the Apple Watch running on battery alone.
Erasing an Apple Watch enables Activation Lock by default when done through a paired iPhone, meaning your Apple Account password will be required afterward before anyone — including you, on a different device — can pair, use, or turn off Find My on that watch again.
If Erase Data is turned on in your watch's passcode settings, entering the wrong passcode 10 times will automatically erase the watch's data as a security measure, separate from any manual reset you initiate yourself.

Know which situation you're actually in first

Before following any specific steps, it's worth identifying which of two genuinely different situations applies to you, since the right method depends on it. If you can currently unlock your Apple Watch — you're selling it, giving it away, or just want to wipe it and start fresh — you have your passcode and your paired iPhone (ideally) available, which gives you the most straightforward and complete reset path. If your watch is locked and you've forgotten the passcode, or it's shown "Too Many Passcode Attempts," you're dealing with a more constrained scenario that requires a full reset regardless, since there's no way to recover or bypass a forgotten Apple Watch passcode directly.

Method 1: Resetting through your paired iPhone (recommended)

If you still have the iPhone that's paired with your Apple Watch, this is Apple's recommended approach, because unpairing through the Watch app does two things at once: it erases the Apple Watch completely, and it automatically removes Activation Lock — a security feature that otherwise remains active and can block the watch from being paired with any other iPhone later, even after a direct, on-watch reset.

Keep your Apple Watch and iPhone close together for the entire process.
Open the Apple Watch app on your iPhone, then go to the My Watch tab.
Tap the (i) icon next to your Apple Watch, then tap Unpair Apple Watch.
Confirm by tapping Unpair [Your Name]'s Apple Watch.
You may be asked to enter your Apple Account password to complete the process.
If your watch has a cellular plan, choose whether to keep it (if you'll pair the watch again later) or remove it (if you won't).

A backup of your Apple Watch's contents is automatically created on your iPhone before the erase completes, which makes restoring your data straightforward if you're setting the same watch back up afterward rather than giving it to someone else.

Method 2: Resetting directly on the Apple Watch

If you don't have your paired iPhone available, or simply prefer to reset from the watch itself, you can do this directly through the Settings app on the watch:

On your Apple Watch, open Settings.
Scroll down and tap General, then tap Reset.
Tap Erase All Content and Settings.
Enter your passcode if prompted, then confirm.

It's important to understand the key limitation of this method: a direct, on-watch reset does not create a backup, and if you don't have the iPhone that's paired with the watch, Activation Lock remains active afterward even though the watch itself is erased — meaning a future attempt to pair it with a different iPhone will still require the original Apple Account credentials.

Method 3: Resetting when you've forgotten your passcode

If you're locked out because you can't remember your passcode, the process is slightly different and requires the watch to be actively charging throughout:

Put your Apple Watch on its charger and keep it there for the entire process — this step is mandatory, not optional, for a passcode-forgotten reset.
Press and hold the side button until the power button appears in the upper-right corner of the display.
Press and hold the Digital Crown until you see the Erase all content and settings option appear.
Tap Reset, then tap it again to confirm.
Wait for the process to finish completely before removing the watch from its charger.

Once the reset finishes, you'll need to set up your Apple Watch again as if it were new, and restore from a backup if one exists and you want your previous data back. One important related detail: if "Erase Data" is enabled in your watch's security settings, 10 consecutive incorrect passcode attempts will trigger an automatic erase on its own — a built-in anti-tampering measure that's separate from, and can happen before, any manual reset you initiate yourself.

Understanding Activation Lock after a reset

Activation Lock is worth understanding clearly, since it affects what happens immediately after any reset method. When an Apple Watch is erased through a paired iPhone (the unpair method), Activation Lock is automatically removed as part of that process. When it's erased directly on the watch without the paired iPhone present, Activation Lock typically remains active, which means your Apple Account and password will be required before the watch can be unpaired from its previous owner's account, paired with a new iPhone, or have Find My turned off — a security feature specifically designed to make a lost or stolen Apple Watch useless to anyone other than its original owner.

If you're selling or giving away your Apple Watch, this distinction matters practically: completing the reset through the paired iPhone's Unpair function, rather than resetting directly on the watch, avoids leaving Activation Lock active and prevents the new owner from running into an unexpected lock screen they can't get past.

What this means if you're resetting your Apple Watch right now

If you still have your paired iPhone and are resetting for a normal reason — selling the watch, fixing a glitch, starting fresh — use the Unpair method through the Watch app. It's the only method that both creates a backup and automatically clears Activation Lock in one step.
If you've forgotten your passcode, make sure the watch is actively on its charger before starting. This isn't a minor suggestion; the forgotten-passcode reset process specifically requires charging power throughout and won't reliably complete on battery alone.
If you're giving your Apple Watch to someone else, always reset it through your iPhone rather than directly on the watch, specifically to avoid leaving Activation Lock active and causing problems for the new owner during their own setup.
Either way, know your Apple Account password before you begin. Both the Unpair method and recovering a watch with Activation Lock enabled require it, and not having it on hand will stop the process partway through.

Frequently Asked Questions

What's the difference between resetting my Apple Watch and unpairing it? Unpairing (done through the paired iPhone's Watch app) both erases the watch and removes Activation Lock automatically. A direct, on-watch reset also erases the watch's content and settings, but doesn't create a backup and typically leaves Activation Lock active if the paired iPhone isn't used to complete the process.

Can I reset my Apple Watch if I don't have the paired iPhone anymore? Yes — you can reset directly through the watch's own Settings app under General, then Reset. However, Activation Lock will likely remain active afterward, requiring the original Apple Account password before the watch can be paired with a different iPhone later.

What happens if I enter the wrong passcode too many times? If "Erase Data" is enabled in your watch's security settings, 10 consecutive incorrect passcode attempts will automatically erase all data on the watch as a security measure — separate from, and potentially happening before, any manual reset you'd otherwise perform yourself.

Do I need to charge my Apple Watch to reset it? For a forgotten-passcode reset specifically, yes — the watch must be on its charger throughout the entire process. For a standard reset where you can still unlock the watch normally, charging isn't a strict requirement, though having sufficient battery before starting is generally a good precaution.
