What resetting a smartwatch means and when to do it

A factory reset erases all your personal data, apps, and settings from your smartwatch and returns it to the state it left the manufacturer. This is different from restarting, which straightforward turns the device off and back on without deleting anything. You should reset your smartwatch if it is running slowly, freezing repeatedly, an app keeps crashing, you are selling or giving it away, or you forgot your PIN and cannot unlock it.

Before you reset, understand that this action cannot be undone. All your saved workouts, downloaded apps, payment information, and personal settings will be gone. If your watch syncs with a phone app—like Wear OS with Google Fit or watchOS with the iPhone Health app—your data may still exist in the cloud, but it will not be on the watch itself after the reset.

Key Takeaways

  • A factory reset removes all personal data and returns your smartwatch to its original state, and this action cannot be reversed.
  • The reset process differs by operating system: Wear OS uses a Settings menu, watchOS requires holding the side button, and Fitbit uses the companion phone app.
  • Charge your smartwatch to at least 50 percent battery before starting a reset to avoid interruption.
  • After a reset completes, you will need to pair the watch with your phone again and sign into your accounts.

Resetting a Wear OS smartwatch

Wear OS smartwatches include devices from Samsung, Fossil, Mobvoi, and others. Open the Settings app on your watch by swiping down from the top of the screen, then swiping left until you see the gear icon. Tap it to enter Settings.

Scroll down and look for "System" or "About phone" (the exact name varies by manufacturer). Tap it, then scroll to find "Reset" or "Factory reset." Tap that option. The watch will ask you to confirm—tap "Yes" or "Confirm." The reset process usually takes two to five minutes. Your watch will restart automatically when it is done.

Resetting an Apple Watch

Apple Watch reset requires access to the physical buttons on the device itself. Hold down the side button (the larger button on the right side of the watch) until you see the power-off slider appear on the screen. Do not release—keep holding. After the slider appears, continue holding the side button for another 10 seconds until you see "Erase all content and settings" appear.

Tap "Erase" on the screen, or if the screen is unresponsive, press the Digital Crown (the rotating dial) and the side button together for about 10 seconds. The watch will begin erasing. This can take several minutes. Once complete, the watch will restart and show the setup screen.

Resetting a Fitbit smartwatch

Fitbit smartwatches (Sense, Versa, and Ionic models) reset through the Fitbit phone app, not through the watch itself. Open the Fitbit app on your phone, tap your profile icon, select your device, and scroll down to find "Clear user data" or "Factory reset." Tap it and confirm.

Some older Fitbit models allow a reset directly on the watch: hold the back button and the bottom button together for 10 to 15 seconds until you see a menu. Select "Clear user data" and confirm. The process takes one to three minutes.

Resetting a Samsung Galaxy Watch

Samsung Galaxy Watches run Wear OS or Tizen, depending on the model year. For newer models running Wear OS, follow the Wear OS instructions above. For older Tizen models, swipe down from the top of the screen and tap Settings. Scroll to "About watch" and tap it. Scroll down to "Reset" and tap it. Confirm by tapping "Yes." The watch will restart after one to three minutes.

Alternatively, you can reset a Samsung Galaxy Watch through the Galaxy Wearable app on your phone. Open the app, tap your device name, scroll down, and select "Reset." This method works for both Wear OS and Tizen models.

What to do after your smartwatch resets

Once the reset is complete, your watch will show the initial setup screen, just as it did when new. Charge it to full battery before proceeding. Then pair it with your phone again by opening the companion app (Google Wear OS, Apple Watch, Fitbit, or Galaxy Wearable) and following the pairing steps.

After pairing, sign into your accounts—Google, Apple ID, or Fitbit—so your watch can sync with the cloud and restore any backed-up data like contacts or calendar events. Reinstall any third-party apps you want. Your workout history and personal stats may reappear if they were saved to the cloud, but this depends on your watch model and whether you were signed into an account before the reset.

Common mistakes to avoid when resetting

Do not unplug or force-restart your watch during a reset. Let it complete fully, even if the screen goes black for a minute or two. Interrupting the process can leave your watch in an unusable state. Charge your watch to at least 50 percent battery before you start—a reset uses significant power, and a dead battery mid-reset can cause problems.

Do not assume your data is gone forever if you were signed into a cloud account. Most smartwatches back up workout data, calendar events, and contacts to the cloud. After you pair and sign in again, some of this data will sync back. However, app settings, downloaded apps, and watch faces will not return—you will need to reinstall and reconfigure those manually.

Frequently Asked Questions

Will resetting my smartwatch remove it from my phone?

Yes. After a reset, your watch and phone are no longer paired. You will need to open the companion app on your phone and pair them again, just as you did when the watch was new. The pairing process usually takes two to five minutes.

Can I reset my smartwatch if I forgot my PIN?

Yes. A factory reset will remove the PIN and all other security settings. Follow the reset steps for your watch model. You will not need to enter the PIN during the reset process itself.

What happens to my workout data after a reset?

Workout data stored on the watch itself will be deleted. However, if your watch was synced with a phone app and your account was active, that data may exist in the cloud. After you reset, pair the watch again and sign into your account—your workout history may reappear, depending on your watch model and the app you use.

How long does a smartwatch reset take?

Most resets complete in two to five minutes. Apple Watch resets can take longer, sometimes up to 10 minutes. Keep your watch plugged in or on the charger during this time to avoid power loss.

Do I need to reset my smartwatch before selling it?

Yes. A factory reset removes all your personal data, accounts, and settings, so the new owner receives a clean device. Always reset before handing over a smartwatch to someone else.
