Brand: Google
Availability: PreOrder

When upgrading to a new Galaxy Watch, you can transfer most settings, apps, and data from your old watch using the backup and restore feature in Galaxy Wearable.

Watch Faces: Installed faces and configurations
Apps: Third-party apps and their settings
Settings: Display, notifications, gestures, and preferences
Health Data: Synced through Samsung Health cloud
Tiles: Your configured tile arrangement

What Doesn't Transfer

Be aware of these limitations:

One UI Version Differences: Settings from One UI 7 won't transfer to One UI 8 if they no longer exist
Hardware-Specific: Features unique to your old model
Watch-Specific Data: Some app data stays on the device
Payments: Samsung Pay and Google Wallet cards need re-adding

Step 1: Back Up Your Old Watch

Before switching, create a fresh backup.

Open Galaxy Wearable app on your phone
Go to Watch settings Account and backup Back up data
Select Back up now
Wait for backup to complete (may take several minutes)
Note the backup date and time for verification

Verify Backup

Check that the backup timestamp is current. Old backups may be missing recent changes.

Step 2: Pair Your New Watch

Set up your new watch and restore during pairing.

Turn on your new Galaxy Watch
Open Galaxy Wearable on your phone
The app should detect your new watch
Follow the pairing prompts
When asked about data transfer, select Restore from backup
Choose the backup from your old watch

Step 3: Restore from Backup

The restore happens automatically during setup.

Select your backup from the list
Choose what to restore (apps, settings, watch faces)

Your new watch will restart with your settings

Troubleshooting Transfer Issues

If restore fails or data is missing:

Check Account: Ensure same Samsung account on both watches
