Disconnect your Apple Watch in the Watch app, not on the watch itself
To disconnect an Apple Watch from your iPhone, open the Watch app on your iPhone, tap the All Watches tab at the bottom, find the watch you want to disconnect, tap the info icon (circle with an "i"), and select Unpair. Confirm when prompted. The watch will restart and erase all data synced from your iPhone — apps, settings, and messages will be removed, though the watch itself will still work with its own storage.
You cannot unpair a watch from the watch itself. The iPhone controls the pairing relationship because it holds the account information and decides what data flows to the watch. If you try to disconnect Bluetooth directly on the watch, you will only break the connection temporarily — it will reconnect the next time the watch and iPhone are near each other and both have Bluetooth on.
The unpair process takes a few minutes. Your watch will show a progress wheel, then restart. During this time, do not force-close the Watch app on your iPhone or turn off either device. Once the watch finishes restarting, it will be factory reset and ready to pair with a different iPhone or to be set up fresh on the same one.
Key Takeaways
- Unpairing happens in the Watch app on your iPhone, not on the watch — the iPhone controls the pairing relationship.
- Unpairing erases all synced data from the watch, including apps, settings, and messages, but the watch itself remains functional.
- Breaking the Bluetooth connection on the watch only disconnects it temporarily; it will reconnect automatically when both devices are nearby.
- The unpair process takes a few minutes and the watch will restart — do not interrupt it or close the app while it is running.
- After unpairing, you can set up the watch with a different iPhone or reset it on the same iPhone from scratch.
Why you might want to disconnect your watch
You may need to disconnect your watch if you are selling it, giving it to someone else, switching to a different iPhone, or troubleshooting a connection problem. Unpairing is also the first step if the watch is not responding correctly or if you want to start fresh with a clean setup.
If you are selling or giving away the watch, unpairing removes your personal data and account information from it. This is important for privacy — the new owner will not have access to your messages, health data, or payment information. The watch will still have its own storage, but nothing tied to your iPhone or Apple ID will remain.
If you are switching to a new iPhone, you do not have to unpair the old watch first. You can straightforward pair it with the new iPhone, and the old pairing will break automatically. However, unpairing first gives you more control over the process and ensures a clean start.
What happens to your data when you unpair
Unpairing erases everything that was synced from your iPhone to the watch: apps you installed, settings you changed, messages and notifications, calendar events, and health data that came from your phone. The watch will keep its own storage — any photos or music you downloaded directly to the watch will remain.
Your iPhone keeps all of its data. Unpairing only affects what is on the watch. If you want to back up any watch-specific data before unpairing, take screenshots of important settings or export health data through the Health app on your iPhone before you start the unpair process.
After unpairing, if you pair the watch with the same iPhone again, you can choose to restore from a backup. The Watch app will offer this option during setup. If you pair with a different iPhone, the watch will set up as new and you will not have the option to restore.
The step-by-step unpair process
On your iPhone: Open the Watch app. Tap the All Watches tab at the bottom of the screen. Find the watch you want to unpair and tap the info icon next to its name (a circle with an "i" inside). Scroll down and tap Unpair [Watch Name]. If you have an Apple Watch Ultra or a cellular model, you may see an option to keep or remove the cellular plan — choose based on whether you want to keep paying for that service.
When you tap Unpair, a confirmation message will appear asking if you want to unpair the watch and erase its content. Tap Unpair again to confirm. The process will begin when ready. Your iPhone will show a progress indicator. The watch will display a progress wheel and then restart — this can take 5 to 10 minutes depending on how much data is being erased.
Do not close the Watch app, turn off your iPhone, or turn off the watch during this process. If the unpair is interrupted, you may need to force restart the watch and try again. Once the watch finishes restarting and shows the Apple logo, the unpair is complete.
Troubleshooting if unpair gets stuck
If the unpair process hangs or the watch does not restart after 15 minutes, force restart the watch. For most models, press and hold both the side button and the Digital Crown for 10 seconds until you see the power-off slider, then swipe to power off. Wait 10 seconds and press the side button again to turn it back on. Then try unpairing again from the Watch app.
If you still cannot unpair, make sure your iPhone and watch are both connected to the same Wi-Fi network and that Bluetooth is on for both devices. Sometimes the connection between them is too weak to complete the unpair. Move them closer together and try again.
If unpairing fails repeatedly, you can also unpair by erasing the watch directly. On the watch, go to Settings > General > Reset > Erase All Content and Settings. This will wipe the watch but will not remove it from your iPhone's Watch app — you will need to manually remove it from the app afterward by tapping the info icon and selecting Remove instead of Unpair.
Pairing a watch with a different iPhone after unpairing
Once you have unpaired the watch, it is ready to pair with a different iPhone. Turn on the watch and hold it near the new iPhone. The new iPhone should detect the watch and prompt you to begin setup. Open the Watch app on the new iPhone, tap Start Pairing, and follow the on-screen steps. You will be asked whether to set up as new or restore from a backup — if this is the first time pairing with this iPhone, you will only have the option to set up as new.
If the watch does not appear on the new iPhone automatically, open the Watch app, tap All Watches, and tap the plus icon to add a new watch manually. Make sure both devices have Bluetooth on and are close to each other.
Temporarily disconnecting without unpairing
If you only want to disconnect the watch temporarily — for example, to troubleshoot a connection issue or to use the watch without syncing data for a while — you do not need to unpair. Instead, you can turn off Bluetooth on your iPhone or on the watch itself. This breaks the connection without erasing any data.
To disconnect temporarily on your iPhone, open Settings > Bluetooth and toggle Bluetooth off. On the watch, open Settings > Bluetooth and toggle it off. The watch will show a red Bluetooth icon with a line through it, indicating it is disconnected. When you turn Bluetooth back on, the watch and iPhone will reconnect automatically and all your data will still be there.
Temporary disconnection is useful if you are having syncing problems or if you want the watch to run independently for a while. The watch can still tell time, run apps that are stored on it, and track activity — it just will not receive new messages or sync data with your iPhone until Bluetooth is turned back on.
Frequently Asked Questions
Will unpairing my watch erase everything on it?
Unpairing erases all data synced from your iPhone — apps, settings, messages, and calendar events. However, anything stored directly on the watch, like photos or music you downloaded to it, will remain. Your iPhone keeps all of its data; unpairing only affects the watch.
Can I unpair my watch without my iPhone?
No, you must use the iPhone to unpair. If you do not have access to the iPhone that the watch is paired with, you can erase the watch directly by going to Settings > General > Reset > Erase All Content and Settings on the watch itself. This will wipe the watch but will not remove it from the iPhone's Watch app.
What if I unpair by accident?
If you unpaired by accident, you can pair the watch again when ready. Open the Watch app on your iPhone, tap All Watches, tap the plus icon, and follow the pairing steps. You will be offered the option to restore from a backup if one exists, which will recover most of your settings and data.
Do I need to unpair before selling my watch?
Yes, you should unpair before selling or giving away your watch. Unpairing removes your personal data, account information, and payment details from the watch. The new owner will receive a factory-reset watch ready to pair with their own iPhone.
Can I use my watch without pairing it to an iPhone?
Yes, an unpaired watch can still tell time, run downloaded apps, track activity, and play music or podcasts that are stored on it. However, it will not receive messages, calls, or calendar notifications, and it cannot sync health data with your iPhone. If your watch has cellular, it can make calls and send messages over cellular without being paired to an iPhone.
