moon phase

Reading the functions

Moon phase.
The center represents earth and the large dot at 12 o’clock represents the sun. Full moon is when the moon is opposite the sun and earth at 6 o’clock. New moon is when the moon is hidden between the sun and earth at 12 o’clock. The new moon is represented by a dark circle at 6 o’clock.

Date.
The 30+1 holes around the perimeter of the dial display the date. The 10 minute markers serve as reference points. For example: the marker indicating 30 minutes also shows the 15th day of the month (30÷2=15). These 5 day markers allow for the date to be read at a glance and after a short time, you can recognize the date intuitively.

Time.
The exact minute and second can be read using the date holes, which are spaced at 2 minute intervals. Holes mark even minutes and gaps odd minutes. The holes and gaps are exactly the same width as the minute hand.
