How to use the moon phase function of the moon phase watchThe usage of the moon phase watch is as follows:
** I. Moon Phase Wheel and Moon Phase Cycle Theory **
1. The moon phase wheel would move one tooth every day and rotate one full circle every two months. The average time of the month was 29.5 days, so the moon phase wheel had 59 teeth. This meant that the changes in the moon's phase were displayed on the dial according to this rhythm.
2. Due to the difference between the exact rotation period of the moon and the moon phase wheel, the error in the moon phase display would reach 24 hours every 33 months.
** 2. Basic operations of moon phase adjustment **
1. ** Based on the 15th day of the lunar calendar **
- During the adjustment, the full moon on the fifteenth day of the lunar calendar was used as the benchmark, and the moon pattern on the moon phase table was aimed at the middle. For example, if today was the second day of the lunar calendar and the end of the lunar calendar last month was the 29th, the adjustment calculation method was 29 minus 15, plus 2. If the lunar calendar had 30 days, then add 1 more day. This kind of adjustment was usually done by the quick adjustment button on the side of the moon phase watch case, or by rotating the dragon head.
2. ** Quick Dialing Notice **
- In most cases, you can speed dial the moon phase in the second gear, but don't speed dial between 3:00 and 4:00 in the morning.(For some watches, such as Blancpain's moon phase watch, you can't use the moon phase fast dial button at 12 o'clock in the afternoon. The workaround is to turn the hour hand back to 8 o'clock or after 4 o'clock, then use the fast dial button to adjust the date or moon phase, and then adjust the time.) Because the gears are in the engaged state, if you force the fast dial, it will cause internal parts to be damaged.
3. ** Illustrate the adjustment steps **
- For example, today was September 8th, and the last full moon was September 4th (you can find it on the Internet). First, adjust the moon phase to the full moon (this time represents September 4th), and then move the four teeth. This is the moon phase on the 8th. Before the operation, the position of the moon had to be adjusted to the center to confirm that it was the fifteenth day of the lunar calendar. Then, based on the fifteenth day of the lunar calendar, he calculated it day by day. Normally, as long as a normal moon phase watch was corrected, it would take two years and seven months before the error would accumulate to one day. If there was a difference of one day, then only on the 15th day of the lunar calendar would there be an obvious difference between the moon phase chart on the watch and the moon in the real night sky. The rest of the days would basically be impossible to see.

How to adjust the moon phase of the Blancpain Moon Phase WatchThe steps to adjust the moon phase of the Blancpain Moon Phase Watch are as follows:
If it was a full calendar moon phase watch and it was a pointer type moon phase, the pointer must first be aimed at the middle of the full moon. The buttons to adjust the moon phase were mostly on the side of the case. Blancpain's full calendar moon phase watch was adjusted on the patent hidden adjustment button behind the ear. Generally, the date, week, and month were adjusted first, and finally the moon phase was adjusted. However, which button corresponded to the moon phase and which button corresponded to the date and month depended on the specific watch model. You needed to refer to the specific watch manual.
Take March 14th, 2017 (the 17th day of the lunar calendar) as an example. There are two days between the 15th day and the 15th day. At this time, you have to pay attention to the number of days ahead, and you have to adjust the calendar to the day before today (if today is the 5th day, then adjust it to the 4th day), and then press the adjust moon phase button according to the calculated number of days (in this case, it is 2 days, press twice).
If it was a Blancpain 5054 moon phase watch, its B button was responsible for the moon phase function. Generally, it was best to adjust it after the 15th day of the lunar calendar. Pressing it once would move the moon back by one day.
Check the full moon date of the previous month (according to the lunar calendar) and calculate the date to today (the date on the watch is the solar calendar). For example, today is July 15th, the last full moon was July 2nd, and today is 13 days. Press the adjustment button on the outside of the case (watches with moon phase function all have an embedded adjustment button, different brands have different positions), press the moon phase to rotate one day until the moon is in the middle of the moon phase plate, and then press this adjustment button 12 times.

The relationship between the moon phase change map and the moon phase nameThe changes of the moon were generally divided into the stages of the new moon, crescent moon, first quarter moon, full moon, moon, waning moon, last quarter moon, waning moon, and so on. In the Moon Phase Change Map, each phase corresponded to a specific moon phase name.
During the new moon, the moon moved between the earth and the sun, with its dark side facing the earth and rising and setting with the sun. This stage was at the starting position in the lunar phase change map, and the moon could not be seen.
The crescent moon appeared after the new moon. Its shape was curved like an eyebrow, and the protruding part of the moon was facing west in an inverted C shape. It was the transition form of the new moon to the upper and lower quarter moon.
The first quarter moon appeared around the seventh day of the lunar calendar. From the northern hemisphere, the right half of the moon was illuminated, forming a semicircle. At this time, the line connecting the sun and the earth was vertical to the line connecting the earth and the moon. It was located in a specific transition position in the moon phase change map.
The full moon was between the first crescent moon and the full moon, and the illuminated part of the moon gradually increased.
The full moon (Wang) appeared at the 15th and 16th of the lunar calendar. The earth was located between the sun and the moon. The side of the moon facing the earth would be illuminated. The round moon could be seen all night. In the lunar phase change chart, it was the phase where the moon was the most illuminated.
Fortunately, after the full moon, the illuminated part of the moon gradually decreased.
The last quarter of the moon appeared around the 22nd of the lunar calendar. The left half of the moon was illuminated from the northern hemisphere, almost in the shape of a semicircle.
The waning moon appeared at the end of the lunar calendar. The protruding part of the moon faced east, like the letter "C." It was the transition from the last quarter of the moon to the new moon. It was close to the beginning of the next cycle in the lunar phase change map.

Moon Phase MapThe moon phase diagram was related to the moon phase. The phases of the moon referred to the different positions of the earth, the moon, and the sun. The parts of the moon that were illuminated on Earth would periodically change and appear in various shapes. The changes of the moon were generally divided into stages such as the new moon, crescent moon, first quarter moon, full moon, moon, waning moon, last quarter moon, and waning moon.
The moon itself did not emit light. It mainly shone by reflecting sunlight. When the moon passes between the earth and the sun (the first day of the lunar calendar), the back of the moon is illuminated by the sun and cannot be seen on earth. This moon phase is called "New Moon"(New Moon). On this day, the moon and the sun rise and set almost at the same time. Soon after the sun sets, the crescent moon can be seen in the western sky.(The protruding part of the moon faces west, forming an inverted C shape); The first quarter moon appears around the seventh day of the lunar calendar.(In the northern hemisphere, the right half of the moon is illuminated, forming a semicircle); At the 15th and 16th of the lunar calendar, the earth is between the sun and the moon, and the side of the moon facing the earth is illuminated, which is the "Wang"(full moon); Around the 22nd of the lunar calendar, the last quarter moon appears (in the northern hemisphere, the left half is illuminated); At the end of the lunar calendar, it is the waning moon (the protruding part of the moon faces east, like the letter "C"), and then the moon phase returns from the waning moon to the new moon, starting a new cycle. The lunar phase changes every 29.5306 days. The moon phase map might be a graphic representation of these different moon phases and related information, used to show astronomical research or popular science purposes such as the law of moon phase changes.

The phase of the moon in a monthThe changes of the moon in a month were as follows:
1. New Moon (New Moon): Appears on the first day of the lunar calendar. The moon is between the earth and the sun, rising and setting with the sun. When observed from the back of the moon, the moon seems to be completely dark.
2. ** Emei Moon **: Appears on the second to seventh day of the lunar calendar. It is shaped like a sickle and can only be seen after sunset.
3. ** First Quarter Moon **: Appears on the 7th and 8th day of the lunar calendar. The sun, earth, and moon form a right angle. It rises at noon and appears in the south sky at dusk. It can be seen in the first half of the night.
4. ** Convex Moon **: Around the 11th or 12th day of the lunar calendar, it will continue to light up and face west. It will set in the west before dawn and can be seen most of the night.
5. ** Full Moon (Wang)**: Appears around the 15th day of the lunar calendar. The sun rises from the east after sunset. Midnight is in the sky due south. It sets in the west in the morning and can be seen all night. At this time, when observing the moon from the direction of the moon, the moon is almost completely bright.
6. Last quarter moon: Appears on the twenty-third day of the lunar calendar. The sun, the earth, and the moon form a right angle. Midnight rises from the east. The sunrise hangs high in the southern sky. At noon, it sets in the west. It can be seen in the second half of the night.
7. Waning Moon: Appears at the end of the 24th lunar month, also known as the second half of the crescent moon. The upper crescent moon appears in the evening and the first half of the night in the western sky, and the lower crescent moon appears in the eastern sky at dawn and the second half of the night.
The cycle of the moon's phase change was 29.5306 days, which was 12:44:3 on the 29th. This cycle was called the lunar month.

Watch the moon phaseThe moon phase watch was a special watch that was mainly used to record the movement of the moon, day and night. There were 59 teeth on the moon phase disk, and one tooth was moved every day. As a result, each set of moon phase patterns had a cycle of 29.5 days, which symbolized the cycle of the moon phase. There would be a " half-moon " window on the dial, and the moon phase plate was usually dark blue with two sets of symmetrical patterns on it, including two round moons with a starry sky in the middle. The moon phase plate and the dial window worked together. As the moon phase plate moved slowly, the first quarter moon, full moon, and last quarter moon would appear in turn.
There were a variety of moon phase watches available at different price points. For example, the 1,000 yuan price range included the Berenceli Collection series of smiling moon phase watches from the Swiss Medo watch. The moon phase plate was uniquely designed, resembling a crescent moon, which could show the dynamic changes of the moon phase well. At the price of 10,000 yuan, there was the Emillon Lemon series moon phase watch, which had a circular moon phase display plate at 6 o'clock, and the dark blue night sky perfectly blended into the plate. At the price of 20,000 yuan, there was the Longines classic replica series military flag watch. In addition, there were more expensive moon phase watches, such as the Blancpain classic series 6654 - 1127 - 55B, which had a highly recognizable face moon phase at 6 o'clock; the Jaeger-LeCoultre Full Calendar Moon Phase Watch, which perfectly integrated the moon phase display at 6 o'clock with the overall layout; Glashütte's original eccentric moon phase watch, with a blue moon phase display window at 2 o'clock. Different brands and styles of moon phase watches have differences in appearance, movement, functions, etc., and can be selected according to their own needs and preferences.

Moon Phase DiagramThe phases of the moon were divided into the new moon, the crescent moon, the first quarter moon, the gradually full moon, the full moon, the gradually waning moon, the last quarter moon, and the waning moon. At the new moon, the moon and the sun were on the same side of the earth. From Earth, the moon was dark, and the moon's phase was almost invisible (because it rose and set at the same time as the sun). The crescent moon was in the shape of a scythe. It could be seen from the second to the seventh day of the lunar month and appeared in the western sky a while after sunset. The first quarter moon was on the seventh day of the lunar month. The sun, earth, and moon were at right angles. It appeared at noon and at dusk in the southern sky. It could be seen in the upper half of the night. The crescent moon was about eleven or twelve, bright facing west, setting in the west before dawn, visible most of the night. During the full moon, the moon and the sun were on opposite sides of the earth. At this time, the moon was almost completely bright. After the sun set, it rose from the east. Midnight was in the south sky, and in the morning, it set in the west, so it could be seen all night. After the full moon, the brightness of the waning gibbous moon gradually decreased. The last quarter of the moon is at twenty-two or twenty-three, and the sun, earth, and moon are once again at right angles. Midnight rises from the east, sunrise hangs high in the southern sky, noon sets in the west, and the second half of the night can be seen. The waning moon was at the end of the twenty-fourth month, also known as the crescent moon in the second half of the month. The difference between the crescent moon and the crescent moon was that the crescent moon appeared in the western sky in the evening and the first half of the night, while the crescent moon appeared in the eastern sky at dawn and the second half of the night. After that, the new moon would return to the new moon, completing a lunar phase cycle of 29.5306 days.
