How to Prepare a Smartwatch for Selling or Giving Away

Why you need to prepare the watch

A smartwatch is a personal device that stores health metrics, message history, contact lists, and often the same payment cards you carry in your wallet. If you sell or give away the watch without clearing it, the next owner may be able to view that data or even use your payment methods. The FTC explains that personal information includes a person's full name, address, phone number, physical location, photos, video and audio recordings, and identifiers that can track activity over time. Much of that data can live on your watch.

There is also a security concern beyond privacy. Most modern smartwatches have an activation lock feature, which ties the device to your account. If you do not remove the lock, the next owner will be greeted with a message asking for your password, and the watch will be unusable to them. Preparing the watch properly is the only way to ensure it is truly ready for its next owner.

Back up your data before wiping

Before you remove anything, consider whether you want to keep the data on the watch. Your health and activity history can often be restored to a new watch if you back it up first. The Apple Watch, for example, lets you back up your watch data to your iPhone automatically, so you can restore it later to a new watch. If you are simply replacing one watch with another on the same phone, check that a backup exists before you unpair.

If you are moving to a different platform, such as from watchOS to Wear OS, your data may not move directly. In that case, export the data you want from the companion app on your phone before resetting the watch. Health data, workout history, and even watch faces can be valuable, so take a few minutes to make sure you have what you need. Once you reset, the data is gone for good.

Unpair the watch from your phone

The first real step is to unpair the watch from your phone. For an Apple Watch, you open the Watch app on your iPhone, tap the watch at the top of the screen, then tap the info button and choose Unpair Apple Watch. This removes the pairing and also creates a fresh backup of your watch data before the reset. The watch will then begin to erase itself.

For Wear OS watches, the process is similar. You open the companion app on your phone (usually the one that manages your watch), find the settings for your watch, and look for an option to disconnect, unpair, or reset. Many Wear OS watches also let you reset from the watch itself by going to Settings, then System, then Disconnect and reset. Unpairing from the phone is important because it breaks the encrypted link between the two devices, so the watch cannot sync your messages, calls, or other data with the phone any longer.

Sign out of your accounts

After unpairing, you should sign out of every account that is logged in on the watch. This includes your primary vendor account (Apple Account, Google Account, Samsung Account, and so on), any email or messaging accounts, and third-party services like music streaming or fitness apps. On Apple Watch, your accounts are managed through the iPhone's Watch app, and unpairing usually removes them. On Wear OS, check the settings on the watch for Accounts or Passwords and remove each one.

Why bother if a factory reset will wipe everything anyway? Because some services keep a device associated with your account even after a reset. For example, your Google Account may list the watch as a trusted device; signing out before resetting removes that association. Also, if you plan to give the watch to a family member who will use the same phone, signing out prevents them from accidentally getting your notifications or your data. If you're selling it, a clean account state is also part of what affects resale value.

Remove payment cards and passes

Payment cards and passes are the most sensitive item on a smartwatch. Both Apple Pay and Google Wallet allow you to store credit and debit cards, transit passes, boarding passes, event tickets, gym memberships, and loyalty cards. According to Google's Wear OS page, Google Wallet on Wear OS can hold boarding passes, event tickets, gym memberships, and loyalty cards. If you leave these on the watch, the next owner may be able to use them.

On Apple Watch, open the Wallet app on the watch, tap a card, and choose Remove. To remove all cards at once, unpair the watch, which also removes all cards and passes. On Wear OS, open Google Wallet on the watch, tap the pass or card you want to remove, then tap Remove. Also check any payment apps that are not from your watch's vendor, such as a banking app, and sign out or remove the card within those apps as well.

For a child's watch or a watch used with a family setup, the process is the same but may involve a parent's approval. If you are giving away a kids' watch, be especially careful to remove any parent-approved contacts and location-sharing settings, since the FTC notes that under COPPA, parents have control over what information companies collect from children, including physical location.

Perform a factory reset

The final step is to wipe the watch completely with a factory reset. This restores the watch to the state it was in when it left the factory: no accounts, no data, no personalization, no stored Wi-Fi networks, no watch faces, no apps beyond the defaults.

On Apple Watch, you can do a factory reset from the watch itself: go to Settings, then General, then Reset, then Erase All Content and Settings. If the watch is paired, unpairing from the iPhone does the same thing automatically. On Wear OS, go to Settings, then System, then Disconnect and reset, and confirm. Some watches also offer a reset option in the recovery menu if the watch is not responding normally.

After the reset, the watch will boot to the initial setup screen, showing a language selection and a prompt to pair. If it does not show this, the reset did not complete, and you should repeat the steps. A watch that boots to setup is clean and ready for its next owner. If you're planning to buy a used watch, our buying used checklist can help you verify it's properly reset.

Check that activation lock is off

After the reset, verify that the watch is not still tied to your account. Activation lock is a security feature that prevents anyone else from using your watch if it is lost or stolen. On Apple Watch, Find My is enabled by default, and the watch remains locked to your Apple Account until you remove it from Find My. If you reset the watch without first turning off Find My or unpairing it in the Watch app, the watch will ask for your Apple Account password when the next person tries to pair it.

To remove the activation lock, go to the Find My app on your iPhone, select the Devices tab, choose the watch, and tap Remove This Device. Or, if you still have the watch paired, unpair it in the Watch app, which automatically disables activation lock. On Wear OS, factory resetting from the watch with your Google Account still on it usually removes the lock, but if you are not sure, verify with the vendor's instructions. The next owner should be able to pair the watch without seeing a lock screen. If they do, walk them through the removal process or keep the watch until you resolve it. Our article on activation lock explains the details further.

Clean the watch before handing it over

While you are preparing the watch, take a moment to clean it. Wipe the display and the back sensor with a soft, slightly damp cloth. Remove any visible dust or debris from the speaker holes and the band attachment points. If you are including the original band, clean it as well. A clean watch is more appealing to a buyer and reduces the chance of skin irritation for the next owner.

Do not use harsh chemicals or abrasive cleaners, as they can damage the display coating or the sensors. A dry microfiber cloth is usually enough. If you are selling the watch, also gather the original box, charging cable, and any documents you still have. These items add value and help the new owner set up the watch without hunting for accessories. For more on what affects a watch's long-term appeal, see our guide to smartwatch repairability.

What to pick for your next watch

Questions

Do I need to unpair the watch before selling it?

Yes. Unpairing removes the encrypted connection, disables activation lock, and automatically creates a backup of your data (on Apple Watch). Skipping this step can leave the watch locked to your account or syncing your data to your phone after you hand it over.

Will a factory reset remove all my payment cards?

A factory reset removes all cards and passes stored on the watch, including Apple Pay and Google Wallet. To be safe, open the wallet app on the watch and manually remove cards before resetting, especially if you are not going to do a full wipe right away.

What is activation lock and why does it matter?

Activation lock ties the watch to your account and prevents anyone else from pairing it. If you reset the watch without removing the lock, the next owner will see a prompt for your password and the watch will be unusable. You remove it by unpairing the watch properly or by removing it from Find My.

How do I know if the watch is clean after resetting?

After a successful factory reset, the watch shows the initial setup screen with a language picker and a prompt to pair with a phone. If the watch instead shows a lock screen or asks for a previous account password, the reset did not complete or activation lock is still on.

Can I give my smartwatch to a family member without resetting it?

You should reset it even for a family member. Your health data, messages, and account information are not appropriate to share. A reset also gives the family member a clean start, so their watch face, apps, and settings are their own.

What should I do with my old watch if I am trading it in?

Follow the same steps: unpair, sign out, remove cards, and factory reset. If the trade-in program provides a shipping label or pre-paid box, clean the watch, include any accessories they request, and ship it securely. You should also remove the watch from your account after the trade-in is processed.
