The moonphase feature on a watch is designed to display the 29.5-day lunar cycle. However, in practice, this is complicated since the moon does not follow an exact 24-hour rhythm. 

In order to adjust the moonphase function pull out the crown to position 2 as explained in the instructions provided. You can then move the moon around in a clockwise direction. The simplest way to set the moonphase dial is to wait until there is a full moon and then set the full moon icon at the top of the dial. However, if you would like to set the moon in its exact phase immediately it is necessary to research the current phase of the moon either online or by an almanac. Remember it will take almost a month for the Moonphase dial to rotate.
