The fastest way to change your Apple Watch time
Your Apple Watch syncs its time automatically from your paired iPhone, so the simplest fix is to check your iPhone's time first. If your iPhone shows the correct time, your watch should update within a few seconds of being near the phone. If your iPhone time is wrong, fix that first by going to Settings > General > Date & Time on your phone, then toggle on "Set Automatically" — this pulls the correct time from your carrier or Wi-Fi network.
If your watch still shows the wrong time after your iPhone is correct, unpair and repair the devices. On your iPhone, open the Watch app, go to the General tab, tap your watch name at the top, then tap the information icon and select "Unpair Apple Watch." After unpairing, put your watch on and hold it near your iPhone to start the pairing process again. During setup, your watch will sync to your iPhone's time.
For most people, this solves the problem. The watch has no independent time-setting controls — it relies entirely on your iPhone. If you travel across time zones, your watch updates automatically when your iPhone does, as long as "Set Automatically" remains on.
Key Takeaways
- Apple Watch does not have its own time-setting menu — it always syncs from your paired iPhone.
- Check that your iPhone's time is correct and set to "Set Automatically" in Settings > General > Date & Time.
- If your watch time is still wrong after your iPhone is correct, unpair the watch and repair it to force a fresh time sync.
- When you travel across time zones, your watch updates automatically if your iPhone's automatic time setting is on.
Why your Apple Watch time might be wrong
The most common reason is that your iPhone's time is incorrect. Because the watch pulls everything from the phone, a wrong iPhone time means a wrong watch time. The second reason is that your iPhone has "Set Automatically" turned off — this setting is usually on by default, but if someone changed it or if you disabled it to test something, your phone stays stuck on whatever time you set manually.
A third reason is that your watch and iPhone lost their connection. This can happen if you've been away from your iPhone for a long time, if Bluetooth turned off, or if you reset your watch without re-pairing it. In these cases, your watch may show the last time it synced, which could be hours or days old.
Rarely, a software glitch causes the watch to stop updating even when paired. This is why unpairing and repairing fixes most stubborn time problems — it forces the watch to re-sync from scratch rather than relying on a stuck connection.
Checking and fixing your iPhone's time setting
Open Settings on your iPhone and tap General. Scroll down and tap Date & Time. You'll see a toggle for "Set Automatically" — make sure it's turned on (the toggle should be green). When this is on, your iPhone pulls the correct time from your cellular network or Wi-Fi, depending on which one you're connected to.
If "Set Automatically" is already on but your iPhone time is still wrong, your phone may not have a strong connection to the network. Try turning Wi-Fi off and on, or moving to a location with better signal. Wait a minute or two for the time to update. If it doesn't, restart your iPhone by powering it off and back on — this often forces a fresh time sync.
Once your iPhone shows the correct time and "Set Automatically" is on, your watch should update within seconds if it's nearby. If it doesn't, move on to unpairing and repairing.
How to unpair and repair your watch to fix time sync
On your iPhone, open the Watch app (the icon looks like an Apple Watch). Tap the General tab at the bottom, then tap your watch name at the top of the screen. You'll see an information icon (a circle with an "i") — tap it. Scroll down and tap "Unpair Apple Watch," then confirm by tapping again.
Your watch will restart and show the Apple logo. Put the watch on your wrist and hold it close to your iPhone. Your iPhone will show a setup screen with an animation — hold your iPhone's camera over the animation on your watch face until the pairing begins. Follow the on-screen prompts to complete setup. During this process, your watch will sync to your iPhone's time automatically.
This process takes about five to ten minutes. Your watch will restore from a backup if you have one, so your apps and settings will return — only the time sync gets a fresh start. After pairing is complete, check that your watch shows the correct time.
What to do if your watch time is still wrong after repairing
If your watch still shows the wrong time after unpairing and repairing, the problem is almost certainly on your iPhone side. Double-check that your iPhone's "Set Automatically" is on and that your iPhone time is correct. Restart your iPhone again and wait a full minute for the time to sync from the network.
If your iPhone time is correct but your watch is still wrong, try restarting your watch. Press and hold the side button until you see the power-off slider, then drag it to power off. Wait ten seconds, then press and hold the side button again until the Apple logo appears. Let your watch restart fully, then check the time.
If the time is still incorrect after all these steps, contact Apple Support. This points to a hardware issue with your watch or a deeper software problem that requires professional help.
Traveling across time zones with your Apple Watch
When you travel to a different time zone, your watch updates automatically as long as your iPhone's "Set Automatically" setting is on. You don't need to do anything — just let your iPhone connect to the network in the new time zone, and both devices will update within a few minutes.
If you want to manually set a time zone for testing or if you're in a place without network coverage, you can't do it on the watch itself. Instead, change the time zone on your iPhone by going to Settings > General > Date & Time and tapping the Time Zone field. Your watch will sync to whatever time zone your iPhone is set to.
If you turn off "Set Automatically" on your iPhone, both your iPhone and watch will stay on whatever time zone you manually set, even if you travel. This is useful if you're traveling for a short trip and want to keep your home time zone, but remember to turn "Set Automatically" back on when you return home.
Frequently Asked Questions
Can I change the time directly on my Apple Watch?
No. Apple Watch has no time-setting menu. It syncs only from your paired iPhone. If you need to change the time, you must change it on your iPhone first, and your watch will update automatically within seconds.
Why does my watch show a different time than my iPhone?
This usually means your watch and iPhone lost their Bluetooth connection. Move them closer together and wait a few seconds. If the times still don't match, unpair and repair the watch. Occasionally, your iPhone's "Set Automatically" is off — turn it back on in Settings > General > Date & Time.
Does my Apple Watch work if my iPhone is off?
Your watch will continue to show the time it last synced, but it won't update to a new time zone or correct a wrong time until your iPhone is back on and nearby. The watch relies on the iPhone for all time information.
What if I don't have my iPhone with me — can I set the time on my watch?
No, you cannot set the time on your watch without your iPhone. If you're away from your iPhone for an extended period, your watch will keep the last time it synced but won't update. Once you reconnect to your iPhone, it will sync to the correct time automatically.
Will my watch time update if I'm in airplane mode?
No. Airplane mode turns off Bluetooth, so your watch can't sync with your iPhone. Turn off airplane mode to allow the sync. Your watch will update to the correct time within a few seconds of Bluetooth reconnecting.
