About the perpetual calendar
In mechanical watches, almanacs and perpetual calendars are tables of complex types. The perpetual calendar is more difficult to design due to the problem of handling the leap year date, so many models also have a leap year display. Considering the changes in the month (including the months of the leap year), it can be displayed until 2100 (the next century year that cannot be divisible by 400). Nowadays, only Franck Muller claims that their Aeternitas watch has a real "perpetual calendar" function, that is, no need to adjust in 100 and 400 years, it is a mechanical wonder.
In terms of appearance, the design of the dial of the perpetual calendar is very high. It can combine messy perpetual calendar instructions, even complex functions such as moon phase profit and loss, chasing function, tourbillon, etc. Some models combine the features of window-opening calendar and pointer calendar, on the faceplate style. The requirements are quite high. It is necessary to design a high degree of visibility of various functions, and it is necessary to have a pointer or window calendar in an orderly manner, and it takes a lot of effort from the designer only in the design of the faceplate.
