Interpretation Of One Of The 6 Major Complications Perpetual Calendar Watch

The perpetual calendar is said to be one of the 6 complication of watches and clocks, and is loved by watch enthusiasts. What is its calendar basis? What does it have to do with a simple, practical and inexpensive annual calendar? What is the relationship between it and other complex functions? Can the perpetual calendar really manage perpetual life?
    Modern watches have three levels of difficulty in the date and calendar display function: first level: calendar, calendar + week (or double calendar); second level: annual calendar; third level: perpetual calendar. The calculation of calendar and week functions is based on 24 hours as a day and night and 7 days and nights as a week. The calculation of the annual calendar is based on 30 days as a month and 12 months as a year. As the length of February is taken into account (28 days on a normal month and 29 days on a leap month), the complexity of the annual calendar has suddenly increased. Due to the leap year every four years, the perpetual calendar naturally becomes more difficult. But this is also where watchmakers and enthusiasts are attracted. The perpetual calendar means achievement.
The artisans in Geneva are known for their hard work and learning. Helping people solve the mysteries and calendars of time has become their special mission to help others. Their help is a watch equipped with the appropriate complication of indicating the calendar, including hours, minutes and seconds, of course.
   The date is indicated on the early clock. Full calendar, which means that the phases including the day, the month, and the usual moon phases appear quickly. By the late 16th century, the calendar appeared on the watch. Even in the early twentieth century, watches had gradually expanded their market share, and manufacturers did not see the business opportunities of putting dates on watches at that time. In 1904, Cartier’s watch for the flying man Santos Dumont was a representative of the modern watch. Flying home only requires hours and minutes, and no calendar. The first watch with only complex features is still in the future. It was not until 1915 that manufacturers recognized the general need for date displays. Since then, dates have become increasingly important in meetings and business life. After a tiring workday, men or women can’t help but glance at the date on their watch, even though they’ve seen it multiple times. So how did these calculations come about, that is, the calendar we commonly use now?
Modern calendar-Zhu Liouli
    In ancient Roman times, the calendar used by the Romans was confusing. Each year contains 12 months, alternating between 29 and 30 days. You don’t have to be a mathematical genius to notice obvious discrepancies between the Roman calendar and the astronomical reality of the solar system. So when the trees sprout in winter, people run to ask the priests, what is going on? Julius Caesar completely repaired the apparently shameless calendar system. His reform is based on the length of the solar year, and this calculation reaches an accuracy of 365 days, 5 hours and 55 minutes.
do you know? New Year’s Day on March 1
    In Julio Caesar’s reformed calendar system, 365 days began on March 1. Then the 6 hours lost every year (precisely 5 hours and 55 minutes) are replenished in February (and the year) every 4 years. The Parliament was encouraged by this, and lawmakers proposed to honor their leaders and use his name to name the month he was born (according to the Roman calendar, the month he was born was the fifth month, or Quintilis). Therefore, our July name is now named after Julio Caesar, July. So how are other months named? Caesar’s adopted son and political heir, Octavius, or Augustus, with a more memorable name, was similarly honored by Parliament. In recognition of his conquest of Alexandria and the removal of Anthony and Cleopatra in the 6th month of 31 BC, the Roman calendar was named after him in June. Augustus. However, unlike Caesar’s July, there are only 30 days in August, which is unacceptable to the future monarch. Therefore, August was changed to 31 days. This means that subsequent months will have to be adjusted accordingly. The day added in August was finally digested this month at the end of the year. Note that the end of the Roman calendar is February. Therefore, February was reduced to 28 days, only 29 days per leap year. This system called Zhu Li’an calendar dominates daily life.
The determination of the modern calendar-Gregorian calendar, there will be no moon in 2100
    The last reform was carried out by Pope Gregory XIII on October 15, 1582. This calendar has been impeccable in the past, and it won’t be noticed until 2100. Unlike the usual leap year cycle, there will be no February 29 in that year. The reason is that Zhu Li’an calendar is 0.0078 days longer than the actual time. To compensate for this error, the leap year has to be cancelled 3 times every 400 years, or in each year that is not divisible by 400 (1700, 1800, 1900, 2100, 2200, etc.). Since the perpetual calendar entered horology, watchmakers have not had to pay too much attention to the Gregorian calendar, because before 1900 to 2100, the perpetual calendar did not need to consider this small error.
Perpetual calendar is displayed more like a fashion trend
    There is no technical difference as to whether the date is indicated by a pointer or a digital dial. The dial display requires a window on the dial, and the pointer display requires the corresponding number to be printed on the dial. The choice of display is basically determined by the fashion and designer’s taste at the time. And interestingly, the disc display and pointer display alternate every few years. This is very much like the fashion trend (although traditional manufacturers are reluctant to associate themselves with fashion, customer tastes determine their business benefits). In general, the digital date display is easier to recognize than the pointer type. Nevertheless, many people still wear glasses to check the date. This is why A.LANGE in the German town of Glashütte initiated a renaissance of the ‘large date’ technology in 1994. That is not a new idea. Since 1932, many Swiss watch factories have begun to use large calendars, such as the square annual calendar model of Sovil. This calendar model has two disks, one for the ten digits and the other for the single digits. In this way, the calendar display can be made larger and easier to read. For example, in 1934, Helvetia’s simpler model, and Mimo’s Mimometer. Movement maker Venus also produced calendar displays. Lange’s advantage did not last long. Soon, others in the industry realized how useful the big calendar is as a complication.
Perpetual calendar watch, only appeared in 1925
    In 1925, the perpetual calendar entered the watch. However, watchmakers have also been ignoring the rules of Pope Gregory XIII. The reason for this is that even if all the conditions are met, it is not necessary to have a practical meaning for a mechanical device to automatically remember the leap year 3 times every 400 years. However, the perpetual calendar is still accurate for 100 years. These 100 years include exactly the year 2000. For any year that is divisible by 400, the leap year and February of that year have 29 days. Unfortunately, the complex mechanical structure of the perpetual calendar is not so easy to appreciate, because it exists in a relatively hidden form. This clever mechanism consists of more than 60 parts and is mounted on a separate splint right on the back of the dial. The perpetual calendar can be paired with different movements. Its brain is the moon. The moon wheel is programmed to have different depressions engraved to indicate different lengths. The tappet responsible for the display is close to the edge of the moon wheel (cam). Day after day determines whether the next month will start on the 28th, or on the 29th, 30th, or 31st. With this system, the perpetual calendar can accurately display the date and month. A simpler, cheaper and more practical variant is the so-called annual calendar. Such institutions only distinguish between the 30th or 31st of the month. Except for February. This month, a simple manual adjustment can keep no adjustment for 365 days. And this annual calendar is enough to ensure accurate display every day.
30 years lunar calendar clock
    Master watchmaker Michel Parmigiani was inspired to repair a Muslim calendar clock. The 30-year uninterrupted lunar clock introduced in 2011 can be calculated with a cycle of 30 lunar years, accurately following Of these, 19 are the average years and 11 are the leap years. Based on the ephemeris of the Paris Observatory, Parma Channing’s thirty-year lunar calendar is a theory because it is based on observations of celestial mechanical movements, because there has not been an uninterrupted lunar design in clock history . No user action is required, the uninterrupted calendar function will automatically change with the lunar cycle; not only that, this lunar calendar clock also provides two different leap year cycle options, you only need to know the applicable lunar calendar first, and Just adjust it locally.
Perpetual calendar is expensive
    For the perpetual calendar, the so-called four-year cycle is the core. This four-year cycle determines the appearance of the next month. Higher steps drive the four-year round. These steps are sensed by the lever and eventually show the correct date. Perpetual calendars have been successively developed and improved by high-end manufacturers. IWC has developed a mechanical device that does not require any error correction facilities and can be adjusted quickly. The moon phases are also controlled, so there is no need to adjust them separately. In 1985, Kurt Klaus, the chief designer of IWC, developed the IWC’s perpetual calendar. This movement has more than 400 parts, and its extraordinary feature is the ease of use. The perpetual calendar shows that the reduction ratio between the longest drive train and escapement train is 6.3 billion to one, and the device has a century-old display. As the name implies, it only needs to be changed once every 100 years to adjust the four digits. The last two digits in the year display. ‘The real ingenuity is that it is easy to use,’ Mr. Claus said. This may point to the design direction of highly complex watches.
