Main features
• Lunar age display feature with smooth continuous movement and small
accumulated error owing to the 24-hour dial, which indicates time in the
one-day cycle rotation, and the lunar age dial, which has almost the same
rotation cycle as the average cycle of movement of the Moon on the celestial
sphere. The figure of eight showing the annual locus of the Sun on the 24-
hour dial (analemma) and the direction of the lunar age marker on the
lunar age dial show the lunar age and positional relationship of the Sun and
Moon and you can see the moon shape easily by referring to the waxing and
waning patterns on the former dial.
• Indication feature of direction and altitude of the Sun and sunrise/sunset
determination feature, which are useful in everyday life. You can see the
direction and altitude of the Sun all through the year and determine sunrise
and sunset by using the position of the Sun on the analemma, the azimuth
and altitude lines and the sunrise/sunset line on the transparent dial. You
can also see sunrise/sunset time.
