Hi forum..setting time issue :-)

[Manzen48]

Hi there,can someone help,i think im right in saying to set the time on on my non hacking airking,i need to put it a bit ahead of the actual time and as the second hand reaches the 12,hold it back by slightly turning crown anti clockwise then releasing at correct time.is this safe for watch.also to check time accuracy is 48 hrs sufficient enough to see +- activity.thks folks if you reply
