The fastest way: use your iPhone

Your Apple Watch pulls the time from your paired iPhone automatically. If the time is wrong on your watch, the simplest fix is to check your iPhone first — it may be set to the wrong time zone or have an incorrect time. Open Settings on your iPhone, tap General, then Date & Time. Make sure Set Automatically is turned on. Your watch should update within a few minutes.

If your iPhone time is correct and your watch is still wrong, unpair and repair the watch. Open the Watch app on your iPhone, go to General, scroll to the bottom, and tap Reset. Choose Erase Apple Watch Content and Settings. Then pair the watch again by holding it near your iPhone and following the setup prompts. The watch will sync to your iPhone's time during pairing.

Key Takeaways

  • Apple Watch gets its time from your paired iPhone, so fixing the iPhone's time usually fixes the watch.
  • Turn on Set Automatically in your iPhone's Date & Time settings so both devices stay in sync.
  • If the watch time is still wrong after checking your iPhone, unpairing and repairing the watch forces a fresh time sync.
  • You cannot manually change the time directly on the watch itself — it must come from your iPhone.

When your iPhone time is correct but your watch shows the wrong time

This usually means the watch and iPhone lost their sync. The watch may be stuck on an old time zone or a time from before you last updated your iPhone. Restarting the watch often fixes this without erasing anything. Press and hold the side button (the button on the right edge of the watch) until you see the power-off slider. Drag the slider to turn off the watch, wait 10 seconds, then press and hold the side button again until the Apple logo appears.

After the watch restarts, it will reconnect to your iPhone and pull the correct time. This usually takes less than a minute. If the time is still wrong after restart, check whether your iPhone's time zone setting matches where you actually are. Open Settings on your iPhone, tap General, then Date & Time, and confirm the time zone is correct for your location.

Changing time zones when you travel

Your Apple Watch changes time zones automatically when your iPhone does, as long as Set Automatically is on in your iPhone's Date & Time settings. When you land in a new time zone, your iPhone detects the change through cellular data or Wi-Fi, and your watch updates within a few minutes. You do not need to do anything manually.

If you are in airplane mode or in a location without cell service, your iPhone may not detect the time zone change. In that case, manually change your iPhone's time zone by opening Settings, tapping General, then Date & Time, and selecting the correct time zone from the list. Your watch will sync to the new time once your iPhone updates.

Why your watch might show the wrong time even after syncing

The most common reason is that your iPhone's time is actually wrong, even if it looks right to you. Your iPhone gets its time from your cellular carrier or Wi-Fi network. If you have been in airplane mode for a long time or switched networks without reconnecting, your iPhone's time can drift. Turning off airplane mode or reconnecting to Wi-Fi usually fixes this within seconds.

A second reason is that your watch and iPhone are not paired correctly. If you see a red X or a warning icon in the Watch app on your iPhone, the devices are not communicating. Restart both your iPhone and your watch, then check the Watch app to confirm they are paired. If the pairing is broken, you will need to re-pair them, which will also sync the time.

What to do if restarting does not work

If your watch time is still wrong after restarting both devices and confirming your iPhone's time is correct, the watch may have a software issue. Check whether a watchOS update is available. Open the Watch app on your iPhone, go to General, then Software Update. If an update is available, connect your watch to power and keep it near your iPhone while the update installs. Updates can take 15 to 30 minutes.

After the update completes, restart your watch again by pressing and holding the side button. The time should now sync correctly. If it still does not, your last option is to erase and re-pair the watch. This is the nuclear option and will delete all data on the watch, but it fixes almost every time-sync problem. Back up your watch data first by opening the Watch app, going to General, and noting any important information, then proceed with the reset described in the first section.

Frequently Asked Questions

Can I manually set the time on my Apple Watch?

No. Apple Watch does not have a manual time-setting option. The watch only gets its time from your paired iPhone. If you need to change the time, you must change it on your iPhone first, and the watch will sync automatically.

Why does my watch show a different time than my iPhone?

This usually means the devices are not synced. Restart both your watch and iPhone, then check that your iPhone's time is correct. If the problem persists, unpair and re-pair the watch. The watch should pull the correct time during the pairing process.

Does my Apple Watch change time automatically when I travel?

Yes, if Set Automatically is on in your iPhone's Date & Time settings. Your watch will update to the new time zone within a few minutes of your iPhone detecting the change. If you are in airplane mode, manually change your iPhone's time zone and your watch will follow.

What if my watch is not paired to an iPhone?

An Apple Watch must be paired to an iPhone to function and to set its time. If your watch is not paired, you cannot use it. Pair it to an iPhone by opening the Watch app and following the setup prompts. The watch will sync to your iPhone's time during setup.
