How to adjust the moon phase on the moon phase watchTo adjust the moon phase function of the moon phase watch, you can follow the following steps:
1. Check the instruction manual or watch online educational videos: The watch's accessory instruction manual usually has teaching content on adjusting the moon phase function, and some brands will also publish educational videos on the Internet. Different brands had different designs, so looking at this information first would help to understand the precautions for adjusting the moon phase function. For example, some watches had time adjustment restrictions.
2. [The reference standard for determining the current moon phase: After mastering the adjustment method, you need to specify the position of the moon during the adjustment.] You can get accurate moon phase information by searching for related tools online (such as time and date). During the adjustment, the new moon could be used as a reference, and the position of the new moon hidden by the two moons on the moon phase plate could be used as the starting point. Then, according to the lunar calendar, it was judged how many days had passed since the last new moon, so as to adjust the correct moon phase. It could also be used as a reference. First, the full moon pattern was placed in the center of the moon phase window, and then adjusted according to the length of time from the last full moon. This could reduce the error.
3. Understand the accuracy of the moon phase function of the watch: The basic moon phase display system uses a 59-tooth gear, and the moon phase period is 29.5 days. However, the actual moon advancement period is not exactly 29.5 days, so the moon phase watch with a 59-tooth wheel will accumulate an error of one day every three months. Therefore, if the watch had this basic moon-phase function, it could be adjusted every three months to ensure the accuracy of the moon phase.
In addition, when adjusting the moon phase, you need to pay attention to avoid the time that is not suitable for the fast adjustment device. For most watches, the hour hand should avoid the range of 8 to 4 clockwise.(Because the gears of the quick dial button are tightly fitted from 8:00 pm to 4:00 am every day, the use of the quick dial button will easily cause the mechanical parts to malfunction.) Some special watches (such as Blancpain's moon phase watch) cannot use the moon phase quick dial button at 12:00 noon. In this case, the hour hand can be set back to 8:00 or after 4:00, and then use the quick dial button to adjust the date or moon phase, and then adjust the time.

There is no moon, what is the moon phase?If the moon was not seen, this moon phase was called the new moon (the first day of the lunar month). At this time, the moon and the sun were on the same side of the earth, called the conjunction of the sun and the moon, called the new moon. Observing the moon from the back of the moon, the moon seemed to be completely dark.

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.

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.

Moon phase timerThe moon phase timer was a part of the watch that had both the moon phase display and timing functions. For example, the Levela 10682 series of Baume et Mercier had a date and moon phase display disc at 6 o'clock on the dial with a translucent design; the traditional Longines watch series L2.773.4.71.2 had a 12-hour countdown disc and moon phase at 6 o'clock; The moon phase display and the 60-minute countdown were placed at 6 o'clock, and the round button could adjust the full calendar and moon phase display respectively. The moon phase counters of these watches had their own unique features in design, function, and layout with other functions.

Changes in the Moon PhaseThe 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.
1. New Moon (New Moon): On the first day of the lunar calendar, the moon moves between the earth and the sun. The back of the moon is illuminated by the sun and people on earth can't see it. The moon and the sun rose and set almost at the same time.
2. Crescent Moon: After the new moon, it appears around the third or fourth day of the lunar calendar. Shortly after the sun sets, a crescent moon shaped like an eyebrow can be seen in the western sky. The protruding part of the moon faces west, forming an inverted C shape.
3. ** First Quarter Moon **: Around the seventh day of the lunar calendar, it appears in the southwest sky in the middle of the night. From the northern hemisphere, the right half of the moon is illuminated, forming a semicircle.
4. ** Full and Convexed Moon (Gradually Full and Convexed Moon)**: Appears in the first half of the lunar calendar, around the eleventh and twelfth of each lunar month. Its shape is similar to that of a full moon, but it is slightly less full than a full moon because it is about to usher in a full moon.
5. ** Wang (Full Moon)**: On the 15th and 16th of the lunar calendar, the Earth is located between the Sun and the Moon. The side of the Moon facing the Earth will be illuminated, and the round moon will be visible all night. However, on the 14th, 15th, 16th, and even 17th of each lunar month, there might be a full moon.
6. ** Waning Convexed Moon (Waning Convexed Moon)**: Appears in the second half of the lunar calendar, around the 18th or 19th of each month. It is shaped like a full moon, but slightly less full than a full moon. Because the full moon has passed, it begins to wane.
7. ** Last quarter moon **: Around the 22nd of the lunar calendar, a semi-circular last quarter moon can be seen in the southeast sky in the second half of the night. From the northern hemisphere, the left half of the moon is illuminated.
8. ** Waning Moon **: At the end of the lunar month, the waning moon can be seen in the eastern sky at dawn. The protruding part of the moon faces east, like the letter "C". The moon's phase returned from the waning moon to the new moon and began a new cycle of changes.
