The quickest way: use your iPhone
Your Apple Watch gets its time from your paired iPhone automatically. If the time is wrong on your watch, the fastest fix is to open the Watch app on your iPhone, tap the Time section, and toggle Set Automatically off and back on. This forces a sync and usually corrects the time within seconds.
If that does not work, go to Watch app > General > Date & Time and manually set the time there. Your watch will update to match. This method works whether your watch is on WiFi, Bluetooth, or cellular. The iPhone is the source of truth for your watch's time, so any change you make there will push to your watch within moments.
Changing the time directly on your watch
You can also change the time without touching your iPhone. On your watch, swipe up from the bottom to open Control Center, then press and hold the time display at the top. Tap Date & Time, then toggle Set Automatically off. Scroll down and tap the time to adjust it manually.
Once you set it manually, your watch will keep that time until you toggle Set Automatically back on — which will sync it to your iPhone again. Manual time changes do not stick permanently; the next time your watch connects to your iPhone, it will revert to the iPhone's time. This is by design: Apple Watch is built to stay in sync with your phone rather than maintain independent settings.
Why your watch time might be wrong
Apple Watch relies on your iPhone to know the correct time. If your iPhone's time is wrong, your watch will be wrong too. Check your iPhone's time first by going to Settings > General > Date & Time and making sure Set Automatically is on. Your iPhone pulls the correct time from your carrier or WiFi network, so if it is set to automatic, it should always be accurate.
If your watch is not syncing with your iPhone, the connection between them may be loose. Restart your watch by holding the side button until you see the power-off slider, then slide to power off. Wait 10 seconds and hold the side button again to turn it back on. Once it restarts, it should pull the correct time from your iPhone. A restart clears temporary connection issues that prevent sync.
Time zones and traveling
When you travel to a different time zone, your watch automatically updates if Set Automatically is on. Your iPhone detects the new location and sends the correct time to your watch within a few minutes of landing. You do not need to do anything manually — the sync happens in the background as long as your devices are connected.
If you are traveling and your watch does not update, manually toggle Set Automatically off and back on in the Watch app on your iPhone. This forces an when ready sync to your current location's time. If your iPhone's time is still showing your home time zone, change that first in your iPhone settings, and your watch will follow.
Keeping your watch time accurate
Leave Set Automatically turned on in your watch settings unless you have a specific reason to change it manually. This ensures your watch always shows the correct time, even when you cross time zones or your iPhone updates its clock. Automatic sync is the default and the most reliable way to keep your watch accurate over time.
If your watch consistently shows the wrong time even with automatic sync on, restart both your watch and iPhone. If the problem persists, unpair your watch from your iPhone and pair it again. Go to Watch app > General > Reset > Unpair Apple Watch, then set it up fresh. Unpairing clears any corrupted sync data that might be causing the time to drift.

Frequently Asked Questions
Why does my watch time keep changing back?
Your watch syncs to your iPhone's time whenever they connect. If you manually change the time on your watch, it will revert to your iPhone's time the next time they sync. To keep a custom time, you would need to change your iPhone's time instead, but this affects all your devices and is not recommended.
Can I set a different time zone on my watch than my iPhone?
No. Your watch always uses the same time zone as your iPhone. If you need your watch to show a different time, you would have to change your iPhone's time zone, which affects all your iPhone apps and notifications.
What if my watch is not paired to an iPhone?
A watch without a paired iPhone cannot set its time automatically. You can manually set the time by holding the side button, swiping to Settings, and tapping Date & Time. The time will stay as you set it until you pair the watch to an iPhone again.
Does my watch need WiFi or Bluetooth to update the time?
Your watch syncs time through Bluetooth when your iPhone is nearby, or through WiFi if your iPhone is not. If your watch is a cellular model, it can also sync through cellular. As long as one of these connections is active, your watch will update automatically.
How often does my watch check for time updates?
Your watch syncs with your iPhone whenever they connect and periodically throughout the day. The exact timing depends on your settings and how often your devices are in range of each other. Restarting your watch forces an when ready sync if you need the time corrected right away.
