* Read the node through the azimuth/altitude
lines on the transparent dial (based on those
at 35° N) to find the approximate position of
the Moon in the celestial sphere at 35° N.
* The actual Moon moves on the moon's path,
which has about 5.1° inclination from the
ecliptic, in inconstant speed. In addition,
considering the distance to the Moon, the size
of the Earth affects the apparent location of the Moon: the altitude of the
Moon from an actual watching point looks lower than that from the center
of the Earth. Use the position of the Moon found only as a rough guide.
* The angle of location range of the Moon are displayed by the maximum
degree from the watch center, which covers the lunar age pointer on the
lunar age dial, including variation range caused with inconstant movement
of the Moon or other reasons.
