The watch normally adjusts its current time setting by syncing with a phone. First confirm there is a connection between the watch and phone. Next, on the watch, check to make sure "Automatic date & time" and "Automatic time zone" are both enabled (ON).
Disable the watch's Airplane Mode.
On the watch, perform the steps below.
Settings > System > Date & time > Automatic date & time > Sync from phone
Settings > System > Date & time > Automatic time zone > Sync from phone
Settings > Connectivity > Airplane Mode > OFF
(The WSD-F10 does not support time calibration by GPS.)
