Maître Cabinotier master craftsman series ‘Astronomica Astronomical Legend’ with its unique quality, not only meet the special needs of customers, but also achieve the perfect combination of excellent watchmaking technology and personalization.
The perfect combination of advanced complication and astronomical display
This watch has functions such as minute repeater, time equation, tourbillon, perpetual calendar, date, week, month, leap year display, power reserve, sunrise and sunset time display and other functions. In addition to the hour and minute hands, the front and dial edges of the watch are equipped with up to 11 concise and unique complications. Two of the most prominent advanced clock functions are the minute repeater and tourbillon. Other astronomical complex functions include perpetual calendar, time difference display and sunrise and sunset time display. Among these exquisite and charming features, the minute repeater function is undoubtedly the most noticeable. The movement is equipped with a unique and unique centripetal chronograph speed regulator, which was developed and manufactured by Vacheron Constantin. This governor is completely silent during operation, and can effectively avoid excessive wear caused by long-term operation. By adjusting the duration of the musical sequence, it is ensured that the scale of the hammer striking the reed can be pleasant every time Beautiful and clear. In addition to the minute repeater, you can watch the delicate tourbillon through the 6 o’clock position of the dial, with a frame made of Vacheron Constantin’s iconic symbol, the Maltese cross. The tourbillon rotates for one full revolution per minute, using anti-gravity technology to make the movement more accurate, and it can also be used as a small seconds display. At the same time, the perpetual calendar, which is called ‘memory of the future time,’ follows a complex Gregorian calendar, and the date needs to be adjusted every four hundred years. The perpetual calendar is displayed symmetrically, with the week at 9 o’clock, the month at 12 o’clock, the date at 3 o’clock, and the leap year at 1 o’clock. Another extraordinary complication of this watch is the time equation function, which displays the superb professional skills through the short hand display at 10:30. This feature is designed to show the minute difference between solar time and standard time. For practical purposes, humans divide the year into 365.25 days, 24 hours a day, 60 minutes per hour, but the time displayed by the sun is the ‘real time’, which is different every day of the year. The resulting error varies from day to day, with a difference of around ± 16 minutes. This remarkable watch also has another astronomical complication that is extremely rare in the field of clocks, namely the sunrise and sunset time display. This feature requires extremely sophisticated production processes to display accurate sunrise and sunset times at a specific location on the planet; therefore, customers need to first select the city where they want to know the sunrise and sunset times. This ‘customized complication’ is displayed strictly symmetrically with sunrise at 8 o’clock and sunset at 4 o’clock.
Revealing the mysteries of the universe
The back of the watch is as stunning as the front. Its features include four complex functions and seven practical and interesting display functions: star map, solstice (winter solstice or summer solstice), equinox, stellar hour, moon Age and moon phases, seasons, and signs of the zodiac. These combinations of astronomical functions are rare in the field of fine watchmaking. This rare dial designed to showcase astronomical functions is divided into two layers. The disc in the center of the dial shows a map of the northern hemisphere and the four basic orientations. The two north-south directions show symmetrically each month and stellar time of the year, and correspond to ‘real time’. Displaying ‘real time’ is necessary for watchmakers, so they can adjust the sky map according to the reference city chosen by each client. The small pointer moving along the edge of the dial on the first layer is used to indicate the age of the month, that is, the number of days from the date of the last full moon. At the same time, the second layer of dial also provides a series of extremely interesting astronomical functions.
The slender center hand rotates around the dial and points to the date on the outer circle, and the other end is decorated with a sun pattern. The pointer also indicates the signs of the zodiac, the seasons, and the equinoxes corresponding to the current date. The day-night equinox indicates that the day and night are equally long, and the day corresponds to the day with the shortest day or the longest day in the year. It appears twice a year to the sun, with the summer solstice around June 21 each year and the winter solstice around December 21. Around the summer solstice, the day time is the longest one year, and around the winter solstice, the day time is the shortest year. The circadian equinox is the highest point over the equator when the solar exchange illuminates the northern and southern hemispheres throughout the year. There are two equinoxes each year, one between March 19 and March 21, and one between September 22 and September 23. The equinox is considered the beginning of spring and autumn, respectively.
Unique from superior movement
The 2755-B1 movement is exemplary in all respects, complementing the unique watch and perfectly matching its owner’s city, which once again proves Vacheron Constantin’s exquisite craftsmanship and innovative wisdom. This timepiece has a variety of complex functions that push the technology to a new level, while always paying attention to the wearer’s habits. Engineers and watchmakers use a large number of delicate parts to create precision movements that perfectly fit the thin and smooth case. The unique design of the platinum case guarantees the flawless sound quality of the minute repeater. In addition, the various display functions are displayed in a balanced and harmonious manner, and ensure clear and readable, which is an art feast presented by the watchmaker. The 2755-B1 movement is entirely developed and manufactured by Vacheron Constantin, perfectly presenting the brand’s excellent concept of designing and manufacturing advanced complex watches. Every component is carefully crafted and perfectly matched with each other to ensure the best performance of the movement, so each movement is an unparalleled masterpiece. The Geneva corrugated decoration of the movement, the carefully hand-chamfered bridge, the round grain-polished main board, and the round and smooth tourbillon frame all show amazing watchmaking techniques. The watch’s entire body and movement are also engraved with the distinguished Geneva mark, demonstrating that it meets the stringent standards of this independent certification mark on the origin, accuracy, durability and professional watchmaking technology of the watch. This symbol of the paradigm of the watch industry also proves that the movement decoration is entirely polished by hand. Watches combine 15 kinds of complex functions into one. This extraordinary design requires superb craftsmanship, which is one of the few in the field of fine watchmaking. The Maître Cabinotier master craftsman series ‘Astronomica Astronomical Legend’ is complex and novel, each one is a unique limited collection.
