To factory reset a Samsung Galaxy Watch, open Settings > General > Reset on the watch (or use the Galaxy Wearable app on your phone), confirm, and let it erase all data and restore factory settings. Before you do, back up your data and remove the screen lock, because on watches signed into a Samsung or Google account a reset can trigger a reactivation lock that requires your password to set the watch up again. This guide walks through the safe order of operations so you don’t lose fitness history or get locked out.
- Back up health and app data through Samsung Health and Galaxy Wearable before resetting
- Remove the screen lock and, on older models, sign out of your Samsung account to avoid a reactivation lock
- After a reset the watch is blank and must be re-paired from scratch
Before you reset: back up and unlock
A factory reset wipes everything on the watch — installed apps, watch faces, Wi-Fi passwords, and locally stored health data. Samsung Health data usually syncs to your phone and the cloud, but confirm the sync completed rather than assuming it did.
- Sync Samsung Health. Open Samsung Health on your paired phone and let it finish syncing. Steps, workouts, heart rate, and sleep records live in the phone app and your Samsung account, so they survive a watch reset when synced.
- Check your backup. In the Galaxy Wearable app, look under settings for a watch backup option. On recent Wear OS-based models (Galaxy Watch4 and later), watch settings and app data can back up to Google. Older Tizen models (Galaxy Watch3, Active2, and earlier) back up through Samsung’s own cloud.
- Note your accounts. Write down the Samsung account and Google account email and password currently signed in on the watch. You may need them to get past the reactivation lock after the reset.
Method 1: Reset from the watch
This is the most reliable method and works even if the watch is no longer paired to a phone.
- Press the Home button and open Settings.
- Scroll to General and tap Reset. On some models the path is Settings > General management > Reset.
- Tap the confirm checkmark or arrow.
- Enter your PIN or pattern if prompted.
- The watch erases all data, restores factory settings, and restarts to the initial pairing screen. This can take a few minutes — keep it on the charger so it doesn’t die mid-process.
Method 2: Reset from the Galaxy Wearable app
If the touchscreen is unresponsive but the watch still connects to your phone, reset it remotely.
- Open the Galaxy Wearable app on your phone.
- Go to the Watch settings tab.
- Tap General (or scroll to the bottom), then choose Reset.
- Confirm. The watch wipes itself and unpairs from the phone.
Method 3: Hardware reset when the screen won’t respond
If the watch is frozen and neither the screen nor the app responds, try a forced restart first: press and hold the Home button (and on two-button models the Back button too) for around 7–10 seconds until it reboots. A forced restart does not erase data. A true factory reset from frozen hardware isn’t guaranteed on every model, so if a forced restart doesn’t restore the screen, contact Samsung support rather than guessing at button combinations that vary by generation.
Reset paths by model family
| Model family | Operating system | Reset path on watch | Backup destination |
|---|---|---|---|
| Galaxy Watch7 / Watch6 / Watch5 / Watch4 | Wear OS (One UI Watch) | Settings > General > Reset | Google account + Samsung Health |
| Galaxy Watch3 / Active2 / Active | Tizen | Settings > General > Reset | Samsung Cloud + Samsung Health |
| Galaxy Watch (2018) / Gear S3 | Tizen | Settings > Reset (or General management) | Samsung Cloud + Samsung Health |
After the reset: re-pair and restore
Once the watch reboots to the welcome screen, it behaves like a brand-new device.
- Open the Galaxy Wearable app and follow the prompts to pair over Bluetooth.
- Sign back into your Google and Samsung accounts when asked — this clears any reactivation lock.
- Choose to restore from your backup if offered, which brings back watch faces, app layout, and settings.
- Reinstall standalone apps and reconnect Wi-Fi. If yours is an LTE model, you may need to re-provision the cellular plan; our guide on whether you need a data plan for a smartwatch covers that.
A clean reset often fixes lingering pairing gremlins. If Bluetooth was the original problem, also see our list of fixes when a smartwatch won’t connect to Bluetooth. And if you reset because the battery drained oddly, our tips to improve smartwatch battery life may help before you assume the hardware is failing.
Frequently asked questions
Will a factory reset delete my step and heart-rate history?
Not if it synced. Samsung Health records that have synced to your phone and Samsung account remain after the watch is wiped. Only unsynced data stored solely on the watch is lost, which is why confirming a sync beforehand matters.
What is Reactivation Lock and how do I turn it off?
Reactivation Lock ties the watch to your Samsung account so a thief can’t reset and reuse it. If it’s on, the watch demands your Samsung account password after a reset. Turn it off — or simply sign out of your accounts and remove the screen lock — before resetting a watch you plan to sell.
How long does a factory reset take?
The erase-and-reboot itself usually takes a few minutes. Re-pairing and restoring a backup afterward can take considerably longer depending on how many apps and how much data you restore.
Do I have to reset to fix a frozen watch?
Usually not. A forced restart (holding the Home button for several seconds) reboots the watch without erasing anything and resolves most freezes and boot loops. Reserve a full factory reset for persistent software problems or preparing the watch for a new owner.
