How to set the time on the Xiaomi Watch S1 Active?
Frequently Asked Questions - 29/03/2026
Response Notice-Facile

To set the time on your Xiaomi Watch S1 Active, you have two options: automatic synchronization via the Mi Fitness app or a direct manual setting on the watch. The simplest and recommended method is to use automatic synchronization, which adjusts the time according to your current time zone.

To access the date and time settings, first turn on your watch by pressing the side button. Then, swipe down from the top of the home screen to open the notification panel, and tap the gear icon to access Settings.

Once in the settings, select System from the menu, then choose Date and time. You will then see an option for automatic update: enable it so that the watch automatically synchronizes with your phone via Bluetooth and adjusts the time according to your time zone. This option is enabled by default and works as soon as your watch is connected to your smartphone.

If you prefer to set the time and date manually, disable the automatic update option, then directly enter the desired time and date on the watch screen. However, note that this manual setting will be overwritten during the next synchronization with the Mi Fitness app if the automatic option is re-enabled.

After making your changes, the settings are saved automatically. If you have changed the time or time zone on your phone, make sure your watch remains connected via Bluetooth to your smartphone for synchronization to occur correctly. You can also manually force a synchronization by opening the Mi Fitness app and pressing the sync button. Your S1 Active watch will then display the exact time corresponding to your location.

GPS & A-GPS

The watch supports the Global Position System (GPS) tracking. When you do outdoor exercises like running, the GPS will automatically start working and notify you when the positioning is successful, and quit tracking once you stop exercises. The open field outdoor is the best place for the GPS tracking; whereas when you are in a dense crowd, raising your arm up can better help GPS to the positioning. It is recommended to start your workout only when the GPS starts working. The watch has an Assisted GPS (A-GPS) feature which can accelerate GPS positioning via the data directly from the GPS satellites. Make sure your watch is connected with the phone via the Bluetooth, the data can be automatically synchronized from app to your watch, and the A-GPS data automatically updated as well. In case the data has not been synchronized for seven consecutive days, the A-GPS data will expire. If so, the positioning information will need to be re-acquired. You can go to the page of outdoor exercises on your watch to update the positioning information.
