The fastest way to change your Apple Watch time
Your Apple Watch syncs its time automatically from your paired iPhone, so the quickest fix is to check that your iPhone's time is correct first. If your watch shows the wrong time and your phone shows the right time, unpair and repair the watch — this forces a fresh sync and usually solves the problem in under a minute.
If you need to set the time manually (for example, if you travel across time zones and want to change it before your phone updates), you can adjust it directly on the watch itself through the Settings app. The process takes about 30 seconds and works the same way on all Apple Watch models.
Key Takeaways
- Apple Watch normally gets its time from your iPhone automatically, so check your phone's time first if the watch is wrong.
- Unpairing and repairing your watch forces a time sync and fixes most time-display problems without manual adjustment.
- You can manually set the time on your watch through Settings > General > Date & Time if you need to change it before your phone updates.
- Turning off automatic time zone detection on your watch lets you set a specific time zone manually for travel.
Check your iPhone's time first
Your Apple Watch pulls its time from your paired iPhone, so if the watch shows the wrong time, your phone probably does too. Open Settings on your iPhone, tap General, then tap Date & Time. Make sure "Set Automatically" is turned on — this uses your phone's location and network to set the correct time.
If "Set Automatically" is already on but the time is still wrong, toggle it off and then back on. This forces your phone to re-sync with the network time server. Wait 10 seconds, then check both devices — they should now match.
Unpair and repair your watch to force a time sync
If your iPhone shows the correct time but your watch does not, unpairing and repairing the watch will force a fresh sync. Open the Watch app on your iPhone, go to the My Watch tab, tap the watch name at the top, then tap the info icon (the small circle with an "i"). Tap "Unpair Apple Watch" and confirm.
Once unpaired, put your watch on your wrist and hold it near your iPhone. The pairing screen should appear on both devices. Follow the on-screen steps to pair them again. During this process, your watch will sync the time from your phone. This usually takes 2 to 5 minutes total.
Manually set the time on your watch
If you want to change the time directly on your watch without waiting for an automatic sync, open the Settings app on your watch (the gear icon on your home screen). Scroll down and tap General, then tap Date & Time.
You will see two options: "Set Automatically" and "Time Zone". If "Set Automatically" is on, your watch will ignore any manual changes you make. Turn it off by tapping the toggle. Once it is off, you can tap the time display and use the digital crown (the rotating dial on the side of your watch) to adjust the hours and minutes. Tap the checkmark when you are done.
Change your time zone for travel
When you travel across time zones, your iPhone and watch normally update automatically based on your location. If you want to set a specific time zone manually — for example, if you are traveling but want to keep your watch on your home time zone — turn off automatic time zone detection on your watch.
Go to Settings > General > Date & Time on your watch and turn off "Set Automatically". Then tap Time Zone and scroll to select the zone you want. Your watch will stay on that time zone even if you move to a different location. To return to automatic updates, turn "Set Automatically" back on.
What to do if your watch still shows the wrong time
If the time is still wrong after unpairing and repairing, restart both your watch and iPhone. On your watch, press and hold the side button until you see the power-off slider, then drag it to turn off the watch. Wait 10 seconds, then press and hold the side button again to turn it back on. On your iPhone, use the standard restart method for your model.
If the problem continues, check whether your iPhone's location services are on — go to Settings > Privacy > Location Services and make sure it is enabled. Your phone uses location to determine the correct time zone. If location services are off, your phone cannot automatically set the correct time. You can also try restarting your router if both devices are on Wi-Fi, since network time sync depends on a working internet connection.
When to restart your watch and iPhone
A restart clears temporary glitches that can cause time sync problems. Restart your watch first: press and hold the side button until the power-off slider appears, then drag it to power down. Wait 10 seconds, then press and hold the side button again until the Apple logo appears.
Then restart your iPhone using the method for your model — for most recent iPhones, press and hold the volume up button and the side button together, then drag the power-off slider. Wait 10 seconds and turn it back on. Once both devices are on, they should sync their time within a few seconds.
Frequently Asked Questions
Why does my Apple Watch time keep changing?
Your watch syncs time from your iPhone every time they connect, so if your phone's time is wrong, your watch will be too. Check that "Set Automatically" is on in your iPhone's Date & Time settings. If your phone keeps changing time zones, location services may be turning on and off — check Settings > Privacy > Location Services.
Can I set a different time on my watch than my iPhone?
You can turn off "Set Automatically" on your watch and set a manual time, but your watch will override it the next time it syncs with your phone. If you want a permanent difference, you would need to turn off automatic sync on your watch and manually update it each time your phone changes time zones.
Does my watch update time automatically when I travel?
Yes, if "Set Automatically" is on in your watch's Date & Time settings and your iPhone has location services enabled. Your watch will detect the new time zone and update within a few minutes of arrival. If you want to keep your watch on your home time zone while traveling, turn off "Set Automatically" and manually select your home time zone.
What if my watch is not paired to an iPhone?
A standalone Apple Watch (Series 3 or later with cellular) can set its own time through Wi-Fi or cellular connection. Go to Settings > General > Date & Time and make sure "Set Automatically" is on. If the time is still wrong, restart the watch and check that Wi-Fi or cellular is connected.
