Apple Watch

On certain Apple Watch models, you can see summaries of your underwater activities in the Depth app. You can also review the summaries in the Fitness app on your iPhone.

You can log almost any underwater activity, from swimming below the surface at the local pool to going on a scuba adventure, as long as you go deeper than 1 meter for more than 5 seconds. The Depth app is supported on the following:

  • Apple Watch Ultra models to a maximum depth of 40 meters (130 feet)
  • Apple Watch Series 10 and later (excluding Apple Watch SE 3) to a maximum depth of 6 meters (20 feet)

WARNING: The Depth app is not a dive computer and does not provide decompression stop information, gas analysis, or other recreational scuba diving functionality.

Apple Watch Ultra models Apple Watch Series 10 and later
On Apple Watch Ultra, the Depth app showing the current depth, time underwater, water temperature, and the maximum depth of the dive. Markers along the left side indicate the depth in feet from 0 to 130. Markers along the right side indicate the depth in meters from 0 to 40. On an Apple Watch Series model, the Depth app showing the current depth, time underwater, water temperature, and the maximum depth of the dive. Markers along the left side indicate the depth in feet from 0 to 20. Markers along the right side indicate the depth in meters from 0 to 6.

What counts as a dive?

You can log almost any underwater activity. That includes swimming below the surface at the local pool, snorkeling and diving down to explore a reef, or going on a scuba adventure.

Your dive is tracked under the following conditions:

  • You use the Depth app or a third-party app that supports underwater activity tracking.
  • Your depth exceeds 1 meter and you’re submerged for more than 5 seconds.

A logged dive can be a single dive, like a scuba dive, or a series of dives aggregated together. That happens, for example, when you’ve submerged multiple times at the pool to work on your breath control.

Begin your dive

Use one of the following methods:

  • Manually: Before you go into the water, open the Depth app.
  • Action button: (supported on Apple Watch Ultra models) If you’ve set the Action button to Dive, press the Action button.
  • Automatically: If you turned on Auto-Launch, the Depth app starts tracking a dive when your depth exceeds 1 meter and you’re submerged for more than 5 seconds.

When submerged, the screen locks and Water Lock is turned on. In the Depth app, screen taps and Digital Crown presses don’t register. Third-party diving apps may allow you to interact with Apple Watch Ultra while underwater by turning the Digital Crown or pressing the Action button.

End a dive

After you surface, end the dive session and turn off Water Lock (which clears water from the speaker) with one of the following methods:

  • Manually: Press and hold the Digital Crown.
  • Action button: (available on Apple Watch Ultra models for dives longer than 3 minutes) If you’ve set the Action button to Dive, press the Action button to end the dive.
  • Automatically: The dive ends when Apple Watch has been out of the water for 10 minutes.

    Note: If you descend again within 10 minutes, your time underwater is added to the previous time you were submerged and is logged as a single dive.

View your recent dives on your Apple Watch

Apple Watch stores a dive summary for 7 days before automatically deleting it.

  1. Start the Depth app on your Apple Watch.
  2. Tap View Recent Dives.
  3. To see more details, tap a dive.

    You can see the date and time the dive started, the maximum depth, and the amount of time underwater.

View your dive history in the Fitness app on iPhone

Your dive summaries from the Depth app appear alongside those created by third-party dive apps, so you can see them all.

  1. Start the Fitness app on your iPhone.
  2. In the Summary tab, tap Sessions, then tap Dives.
  3. Tap a dive to see such details as maximum depth, underwater time, water temperature, and more.

To delete a dive, swipe left on the dive, then tap Delete.

If something isn’t working right, try restarting your Apple Watch and its paired iPhone.

Restarting your Apple Watch means turning it off and on with the side button, but you can’t restart your Apple Watch while it’s charging. You can also force Apple Watch to restart, and restart the paired iPhone.

Change or turn off your passcode, and choose whether to use a simple four-digit passcode. For added security, you can also set Apple Watch to erase its data after 10 failed unlock attempts.

Your Apple Watch passcode can be different from your iPhone passcode, and it’s better to use different passcodes. There’s a catch, though. If you turn off your passcode on your watch, some features won’t be available, such as Apple Pay.

Note: You may be prevented from using a simple passcode or turning off your passcode if your synced iPhone is managed by an organization, such as a company or school. Check with your organization’s administrator.

Change your passcode

  1. Open the Settings app on your Apple Watch.
  2. Tap Passcode, tap Change Passcode, and then follow the onscreen prompts.

    Tip: Your Apple Watch passcode can be different from your iPhone passcode—in fact, it’s better to use different passcodes.

Note: If you turn off your passcode, some features won’t be available. For example, you can’t use Apple Pay or unlock your Mac with Apple Watch.

  1. Open the Settings app on your Apple Watch.
  2. Tap Passcode, then tap Turn Passcode Off.

You can also go to the Apple Watch app on your iPhone, tap My Watch, tap Passcode, then tap Turn Passcode Off.

Erase Apple Watch after 10 unlock attempts

If Apple Watch is lost or stolen, you can protect your information by having Apple Watch erase its data after 10 consecutive attempts to unlock it with the wrong passcode.

  1. Open the Settings app on your Apple Watch.
  2. Tap Passcode, then turn on Erase Data.

  • Erase your Apple Watch. This erases all content and settings from Apple Watch, but leaves it paired with your iPhone. Do this if you plan to keep your Apple Watch, and just need to reset it.

Unpair Apple Watch and remove Activation Lock

  1. Open the Apple Watch app on your iPhone.
  2. Tap My Watch, then tap All Watches.
  3. Tap the Info button next to your watch and tap Unpair Apple Watch.

Your Apple Watch is erased and removed from your Apple account, Activation Lock is removed, and your watch is ready to be set up again.

  1. Open the Settings app on your Apple Watch.
  2. Tap General, then tap Reset.
  3. Tap Erase All Content and Settings. Then enter your passcode.
  4. If you have an Apple Watch with cellular, choose to keep or remove your cellular plan.
    • Keep your plan if you want to pair your Apple Watch and iPhone again.
    • Remove your plan if you want to pair your Apple Watch with another iPhone or intend to cancel your cellular subscription. (Contact your carrier to cancel your subscription.)
  5. When the process finishes, set up your watch again. When asked, restore from a backup.

You can also go to the Apple Watch app on your iPhone, tap My Watch, tap General, tap Reset, then tap Erase Apple Watch Content and Settings.

Note: If you can’t access the Settings app on your Apple Watch because you’ve forgotten your passcode, you must reset it.

You can remove the cellular plan at any time on an Apple Watch with cellular.

  1. Open the Apple Watch app on your iPhone.
  2. Tap My Watch, tap Cellular, and tap the Info button next to your cellular plan.
  3. Tap Remove [carrier] Plan, then confirm your choice.

Your Apple Watch is backed up automatically to your paired iPhone, and you can restore it from a stored backup. Apple Watch backups are included when you back up your iPhone—either to iCloud, or to your Mac or Windows device.

If your backups are stored in iCloud, you can’t view the information in them. But if you get a new Apple Watch, you can restore it from one of those backups.

Back up and restore Apple Watch

  • Back up your Apple Watch: When paired with an iPhone, Apple Watch content is backed up continuously to the iPhone. If you unpair the devices, a backup is performed first.
  • Restore your Apple Watch from a backup: If you pair your Apple Watch with the same iPhone again, or get a new Apple Watch, you can choose Restore from Backup and select a stored backup on your iPhone.

An Apple Watch that’s managed for a family member backs up directly to the family member’s iCloud account when the watch is connected to power and a Wi-Fi network. To disable iCloud backups for that watch, go to the Settings app on the managed Apple Watch, tap [account name], tap iCloud, tap iCloud Backups, then turn off iCloud Backups.

To use your Apple Watch, you need to pair it with your iPhone. Setup assistants on your iPhone and Apple Watch work together to help you pair and set up your watch.

Your watch needs watchOS 27, on Apple Watch SE 3, Series 9, Ultra 2, or later, and your iPhone needs iOS 27, on iPhone 11 or later. It’s a good idea to update your iPhone first. Then, if your watch has cellular, you can activate cellular service.

WARNING: To avoid injury, read Important safety information for Apple Watch before using your Apple Watch.

What you need

To set up Apple Watch, you need the following:

  • Apple Watch SE 3, Apple Watch Series 9, Apple Watch Ultra 2, or later with watchOS 27 or later
  • iPhone 11 or later with iOS 27 or later

Before you begin

  • Update your iPhone to the latest version of iOS: Go to the Settings app on your iPhone, tap General, then tap Software Update.
  • Make sure that your iPhone has Bluetooth turned on, and it’s connected to a Wi-Fi or cellular network: To check, swipe down from the top-right corner of the iPhone screen to open Control Center. Make sure that Bluetooth and Wi-Fi (or Cellular) are highlighted.

Step 1: Turn on and pair your Apple Watch

Quick tip: VoiceOver or Zoom can help if you have difficulty seeing your Apple Watch or iPhone, even during setup. See our guide, Set up using VoiceOver, or our article, Use Zoom.

  1. Put your Apple Watch on your wrist. Adjust the band or choose a band size so your Apple Watch fits closely but comfortably.
  2. To turn on your Apple Watch, press and hold the side button until you see the Apple logo.

    If your Apple Watch doesn’t turn on, you might need to charge the battery.

  3. Hold your iPhone near your Apple Watch, wait for the Apple Watch pairing screen to appear on your iPhone. Then tap Continue.

    You can also go to the Apple Watch app on your iPhone, then tap Start Pairing.

  4. Tap Set Up for Myself.
  5. When prompted, position your iPhone so that your Apple Watch appears in the viewfinder in the Apple Watch app. This pairs the two devices.

Step 2: Set up your Apple Watch

  1. If this is your first Apple Watch, tap Set Up Apple Watch and then follow the instructions on your iPhone and Apple Watch to finish setup.

    If you’ve set up another Apple Watch with your current iPhone, a screen appears that says Make This Your New Apple Watch. Tap Apps & Data and Settings to see how Express Setup will configure your new watch, then tap Continue. To choose how your new watch is set up, tap Customize Settings. Next, choose a backup from a previous Apple Watch to restore. Or tap Set Up as New Apple Watch if you want to fully customize your new device’s settings.

  2. Follow the onscreen instructions to set up the following:

    • Sign in to your Apple Account.
    • Create a passcode—either a standard four-digit passcode, or a long passcode, which requires six digits.
    • Customize settings for text size, optionally enter personal information such as date of birth and height that are used for fitness and health, and choose the health notifications you want to receive.

    You can change these settings after you’ve set up your Apple Watch.

Step 3: Activate cellular service

If you have an Apple Watch with cellular, you can activate cellular service during setup. If you’ve set up Apple Watch, you can activate cellular later in the Apple Watch app on your iPhone. See Set up and use cellular service.

Your iPhone and Apple Watch need to use the same cellular carrier. The exception is an Apple Watch you set up for someone in your Family Sharing group, since that watch can use a different cellular carrier from the one on the iPhone you manage it with.

Note: Cellular service isn’t available in all countries or regions.

Step 4: Keep your devices close as they sync

Your Apple Watch shows the watch face when syncing finishes and your watch is ready to use.

To learn more about your Apple Watch while it’s syncing, tap Get to Know Your Watch. You can learn what’s new, view Apple Watch tips, and read this user guide, right on your iPhone. To find this information after your Apple Watch is set up, open the Apple Watch app on your iPhone, then tap Discover.

An iPhone and Apple Watch, side by side. The iPhone screen shows “Apple Watch is Syncing.” The Apple Watch shows syncing progress.

Trouble pairing?

  • If you see a watch face when you’re trying to pair: Your Apple Watch is already paired with an iPhone. You need to first erase all Apple Watch content and reset settings.
  • If the camera doesn’t start the pairing process: Tap Pair Apple Watch Manually at the bottom of the iPhone screen, then follow the onscreen instructions.
