2024 has brought us some incredible calendar watches, showcasing the mastery and complexity of watchmaking. One standout is a modern twist on the classic Tuscan dial perpetual calendar, featuring a mesmerizing "Crystal Sky" textured dial. This model holds sentimental value as it is the last to be powered by the self-winding perpetual calendar calibre 5134, which has been a staple of the brand since 2015.
Another remarkable timepiece is the CVDK Grand Planetarium Eccentric, a marvel of mechanical ingenuity. Designed by Mister van der Klaauw and Koeslag, this watch incorporates all the planets of the Solar system, following their eccentric paths for maximum accuracy. It also displays the time, calendar indications, and zodiac signs, making it a true work of art.
IWC's first secular perpetual calendar is another noteworthy addition to the list. This model features a calendar function that won't need adjusting until the year 3999 and includes a moon phase indicator that remains accurate for 45 million years, a world record. What sets this watch apart is its mechanical simplicity, with a 400-year gear system designed to handle leap years over four centuries, consisting of just 8 components.
Patek Philippe also makes an appearance with their In-Line Perpetual Calendar 5236P. This watch showcases a compact yet highly practical display of the calendar indication on a single line, with non-underlapping discs for day, date, and month. The platinum case and salmon-toned dial add a touch of elegance to this mechanically impressive timepiece.
