Moon Phase Graph Watches

Moon phase graph displays phases of the moon. A regular rotation of the moon is once around the earth every 29 days, 12 hours, and 44 minutes. Once set, the moon phase indicator accurately displays the phase of the moon. The progression of moon from one phase to another is shown on a small moon phase disc of the watch. One can follow the lunar calendar, and know the astronomical moon phases. Watches that display moon phase information are used by hunters, fisherman, surfers and sailors. The lunar calendar is probably the oldest calendar system around. It marked days after a certain event or happening and flood preparation for those areas close to rising tides.
