Welcome to the Fitbit Community, @timotei.
I am sorry to hear your Versa Lite is losing time. Thank you for trying to resolve this and providing the additional details. I understand how you are feeling and I am here to help. Time on your watch should be corrected when you sync it. I recommend doing the following:
- Verify if the Fitbit app is updated to the latest version. See this link.
- Force quit the Fitbit app.
- Reboot your phone.
- Restart your Fitbit with the steps from this help article.
- Open the Fitbit app, tap on your profile picture > Set Up a Device.
- Choose your Fitbit from the list and follow the onscreen instructions.
For complete troubleshooting instructions, see Why can't I set up my Fitbit device?
Make sure your watch syncs to the Fitbit app throughout the day. You can find more information about syncing your device at How do Fitbit devices sync their data? If the issue still persists after syncing, you can also check the additional troubleshooting steps here.
Keep me posted on the outcome.
