A. Check the settings within the Wearfit Pro app. Navigate to 'Settings' > 'Time Format' and see if there is an option to switch between 12-hour and 24-hour formats. If not available, check your phone's system settings to ensure it is set to 12-hour format, as some apps may follow the phone's settings.

B. If the app does not support a 12-hour format, consider using a third-party watch face app that allows for more customization, including time format options.
