In 46 BC, the Egyptian astronomer Sosigenes formulated the basis of the modern calendar: a year is divided into twelve months, of which seven months have 31 days, four months have 30 days, and one month has 29 days, or 365.25 days a year, one day in four years. Later, the Roman Emperor Nishizawa extended the Julian calendar to all parts of the world, but the disadvantage of this calendar is that there is still an error of 0.0078 days per year. By 1582, Pope Gregory XIII proposed reforms, and any year that was a multiple of 100 but not a multiple of 400 did not have a leap year, which resolved the problem of errors; the Gregory calendar, named after it, still measures time. this.
In this calendar, the number of days in different months is different. Normal mechanical calendar watches will only jump from day 30 to day 31. If the next month is less than 31 days, manually adjust to day 1.
However, not only can the perpetual calendar watch automatically handle the days of the month and month, but also the leap year is accurate, which involves extremely complex mechanical structures, so the perpetual calendar is also known as one of the most advanced watchmaking technology. Today’s perpetual calendar system does not need to be manually adjusted until 2100. Although 2100 is a multiple of 100, it is not a multiple of 400, so it is not a leap year.
For watch enthusiasts who love the perpetual calendar craftsmanship, the Bucherer Marie Long Perpetual Calendar Chronograph is a model of the art of timepieces: a date display at 12 o’clock, a week display at 6 o’clock, a month and leap year display at 9 o’clock and 3 o’clock The moon phase of the position is accurate for 100 years. This unique Bucherer movement also has a flyback timing function. The outer edge of the dial has a speedometer scale, which is consistent with the brand’s philosophy of focusing on practical functions. The Maliron Perpetual Calendar Chronograph is based on a movement developed by the Vaucher movement factory, but the details are modified in accordance with the original nature of Bucherer.
Although the Marly Dragon Perpetual Calendar Chronograph is multifunctional, it has been carefully arranged by the designer, using different levels and modifications to make the layout and display clear and easy to read: for example, the hour timer at 6 o’clock and the minute timer at 9 o’clock And the small seconds at 12 o’clock, which are respectively embedded in the slightly concave calendar display, with black lines to delineate different scales.
The central chronograph seconds hand, three-dimensional hour markers, the unique characters and numbers of Bucherer, the sword-shaped luminous hours, the minute hand, and three implicit black chronograph indicators put a new look on traditional perpetual calendar functions. The elegant silver dial is matt-finished in the central part, and the timer and minute scales are matte-treated to present a pleasing gloss contrast; the moon phase is lined with a silver moon on a carbon black background, and it also sees a rich contemporary design touch.
