If the watch is running try to sync the watch 1st, meaning set the minute and hour hands pointing to 12:00 o'clock. before you go to set the time.

You need to manually adjust or set the hands to the home position as they are not where the watch thinks they should be. This can happen when you bring your watch close to a strong magnetic field. Look in the manual to do this. Afterwards your watch should set to the correct time.
