Why Is the Time Wrong on My Z40 Smart Watch?
Before diving into the fix, it helps to understand why your Z40 might be showing the wrong time. Most smart watches, including the Z40, rely on synchronization with a smartphone to keep accurate time. If that connection is broken—or if settings get changed—your watch can fall out of sync.

Common reasons include:
- Bluetooth disconnection: If your watch isn’t connected to your phone, it can’t receive time updates.
- Time zone mismatch: Traveling without updating your phone’s time zone can throw off your watch.
- Daylight saving time changes: Some devices don’t auto-adjust unless properly configured.
- App or firmware glitches: Outdated software can cause syncing errors.
- Manual override: If someone (or you) changed the time manually and forgot to switch back to auto-sync.
Understanding these causes helps you choose the right solution—and avoid repeating the problem.
Method 1: Sync Time Automatically via Bluetooth
The easiest and most reliable way to ensure your Z40 shows the correct time is by syncing it with your smartphone. This method uses Bluetooth to pull the current time and date from your phone, which is usually set to update automatically via network time servers.
Step 1: Ensure Bluetooth is Enabled
First, check that Bluetooth is turned on both on your phone and your Z40 watch. On your phone, go to Settings > Bluetooth and make sure it’s switched on. On the Z40, swipe down from the top of the watch screen to access quick settings and tap the Bluetooth icon to confirm it’s connected.
Step 2: Open the Companion App
The Z40 smart watch typically works with apps like Da Fit, H Band, or Amazfit, depending on the model and region. Download the correct app from the Google Play Store or Apple App Store if you haven’t already.
Once installed, open the app and log in or create an account if required. Then, follow the on-screen instructions to pair your Z40 with your phone. This usually involves scanning for nearby devices and confirming a pairing code.
Step 3: Enable Auto Time Sync
After pairing, go to the app’s main dashboard and look for a section labeled Device, My Watch, or Settings. Tap on your Z40 device name to access its settings.
Look for an option like “Sync Time”, “Automatic Time”, or “Use Phone Time”. Toggle this setting to On. This tells the watch to regularly check your phone’s time and update itself accordingly.
Step 4: Force a Sync
To make sure the change takes effect immediately, force a sync. In the app, look for a “Sync Now” button—usually found in the device settings or main screen. Tap it, and wait a few seconds. You should see a confirmation message or a spinning icon indicating the sync is in progress.
Once complete, check your Z40’s watch face. The time should now match your phone’s time.
Pro Tip: Keep Your Phone’s Time Accurate
For this method to work, your phone must have the correct time. On Android, go to Settings > System > Date & Time and enable “Automatic date & time”. On iPhone, go to Settings > General > Date & Time and turn on “Set Automatically”.
Method 2: Change Time Manually on the Z40 Watch
Sometimes, automatic syncing doesn’t work—maybe you’re in an area with poor signal, or your phone is off. In these cases, you can manually set the time directly on your Z40.
Step 1: Access the Settings Menu
On your Z40, swipe left or right from the watch face to navigate to the app menu. Look for a gear or wrench icon labeled “Settings”. Tap it to open.
Step 2: Find the Time or Date & Time Option
Scroll through the settings menu until you find “Time”, “Date & Time”, or “Clock”. Tap to enter this section.
Step 3: Disable Automatic Time (If Enabled)
If there’s a toggle for “Automatic Time” or “Sync with Phone”, turn it off. This allows you to manually adjust the time without the watch overriding your changes.
Step 4: Set the Time Manually
You’ll now see options to adjust the hour, minute, and possibly AM/PM (if using 12-hour format). Use the on-screen controls—usually up and down arrows or a scroll wheel—to set the correct time.
Some Z40 models may require you to tap each field (hour, minute) individually. Take your time to ensure accuracy.
Step 5: Confirm and Save
Once the time is correct, look for a “Save”, “OK”, or “Confirm” button. Tap it to apply the changes. The watch face should update immediately.
Bonus: Adjust Date and Time Zone
While in the same menu, you can also set the correct date and time zone. This is especially useful after traveling. Select your current time zone from the list to ensure daylight saving and regional time changes are applied correctly.
Method 3: Use the Companion App to Set Time Remotely
Many Z40 users don’t realize they can adjust the time directly from their phone using the companion app. This is especially handy if the watch screen is hard to navigate or if you’re setting it up for someone else.
Step 1: Open the App and Connect
Launch the app (e.g., Da Fit) and ensure your Z40 is connected via Bluetooth. You should see your device listed and marked as “Connected.”
Step 2: Navigate to Device Settings
Tap on your Z40’s name or icon to open its settings. Look for a section like “General”, “System”, or “Time Settings”.
Step 3: Adjust Time and Date
Some apps allow you to manually input the time and date. If available, tap on the time field and enter the correct values. You may also be able to select your time zone from a dropdown menu.
Step 4: Sync the Changes
After making adjustments, tap “Save” or “Apply”. Then, use the “Sync Now” feature to send the updated settings to your watch. Wait a few moments for the sync to complete.
Note: App Limitations
Not all Z40 models or apps support remote time setting. If you don’t see these options, stick to manual or automatic sync methods.
Troubleshooting Common Time Issues
Even with the right steps, things can go wrong. Here’s how to fix the most common problems when changing the time on your Z40.
Problem: Time Doesn’t Update After Sync
Solution: First, check your Bluetooth connection. Disconnect and reconnect your watch in the app. Then, restart both your phone and the Z40. Turn the watch off by holding the side button, wait 10 seconds, then turn it back on. Try syncing again.
Problem: Watch Shows Wrong Time Zone
Solution: Go to your phone’s settings and verify the correct time zone is selected. Then, in the companion app, check if there’s a time zone override. If so, disable it to let the watch follow your phone.
Problem: Daylight Saving Time Not Applied
Solution: Ensure your phone’s automatic time setting includes daylight saving adjustments. On Android, this is usually enabled by default. On iPhone, “Set Automatically” handles it. If your region observes DST, your Z40 should follow once synced.
Problem: Manual Time Resets After Reboot
Solution: This usually means automatic sync is still enabled. Go back to the settings menu on the watch and turn off “Automatic Time” before making manual changes. Alternatively, disable auto-sync in the app.
Problem: App Won’t Connect to Watch
Solution: Force close the app, restart your phone, and try pairing again. Make sure the watch is in pairing mode (usually by holding the side button until a Bluetooth icon appears). If problems persist, uninstall and reinstall the app.
Tips for Maintaining Accurate Time on Your Z40
Once your time is set correctly, follow these best practices to keep it that way:
- Keep Bluetooth On: Enable Bluetooth whenever possible to allow regular syncing.
- Update the App and Firmware: Check for app updates monthly and install firmware updates when prompted. These often include bug fixes for time sync.
- Avoid Manual Overrides: Unless necessary, let the watch sync automatically to prevent confusion.
- Check After Travel: When flying, update your phone’s time zone before syncing your watch.
- Restart Weekly: A simple restart of your Z40 every week can prevent glitches and improve performance.
When to Consider a Factory Reset
If none of the above methods work and your Z40 consistently shows the wrong time, a factory reset may be necessary. This restores the watch to its original settings, which can resolve deep software issues.
How to Factory Reset Your Z40
Go to Settings > System > Reset or Factory Reset on your watch. Confirm the action when prompted. Note: This will erase all data, including health stats and custom watch faces. Back up any important info first.
After resetting, re-pair your watch with your phone and set up time sync again.
