Interesting article from Monochrome that offers a technical perspective on the types of calendar watches. From the simple display of just the date that is used by many luxury watch makers to the secular perpetual calendar from Patek and others.

Among the amazing timepieces featured in this article is the Frank Muller Aeternitas Mega 4. It has 36 different complications geared by 1483 parts. The watch’s calendar mechanism is calibrated to reproduce leap years on 4 years, no leap years on 100 years, leap years on 400 years cycles. Quite remarkable!
