BaselWorld 2012: Carl F.Bucherer represents a masterpiece in the category “grande complication” with innovative indication of moon phases - a Manero Perpetual Watch

The annual international watch exhibition BaselWorld 2012 has become the place of the next novelty’s presentation by the watch company Carl F.Bucherer, submitted an original watch Manero Perpetual.
The peculiarity of the model has become the movement, requiring no configuration, that operates on the basis of the Gregorian calendar and able to take into account the duration of each month and the cycle of leap years.
The creators of the model are proud to say that the need for manual configuration of the represented watch will be only after two generations – but not only in a leap 2100th year. The history of the calendar that we all use is rooted in 46 BC. It was then that the Alexandrian astronomer Sozigen developed the principles of the calendar. Each year he divided into 12 months, seven months of 31 days, four months of 30 days and one month - of 29 days.
This calculation assumed the duration of the calendar year to 365.25 days. And to compensate for a quarter of day it was decided that every fourth year will consist of 366 days.
This type of calculation has been called "Julian calendar" because thanks to the Emperor Julius Caesar was adopted throughout the world.
However, this system had an error of calculation, component of 0.0078 days per year, which was amended in 1582 by Pope Gregory XIII. According to the Gregorian calendar system, which got its name from the pope, leap years are not multiple to 100 and non-multiple to 400. This system was quite acceptable and solved many of the errors in chronology, remained in use until today.
Indication of the perpetual calendar has become in watchmaking one of the most elite of complications that only a company with highly skilled professionals can afford.
Thus, the function of the perpetual calendar is the most difficult watch feature of the highest category. However, each holder of the mechanical watch with date display function is familiar with the problem connected with different duration of months of the year. Usually after 30 days of the month the usual mechanical calendars are automatically switched to the 31th, so in the months of duration less than 31 of the day the owner of the watch have to manually rearrange the date of the first day.

However the mechanisms with perpetual calendar perform adjustments and an amendment to the leap years automatically. These mechanisms are extremely complex and rightly included in the top category of complex time functions - the so-called grand complication. The immediate adjustment by hand, which is needed for such mechanisms, need only in 2100, which according to the rules of the Gregorian calendar is not considered a leap year.
