The world of calendar watches is expansive, showcasing a variety of mechanisms from the straightforward to the extraordinarily complex. Ranging from classic triple calendar models that require manual adjustment to the technological marvels of secular perpetual calendars, which effortlessly adapt to the quirks of the Gregorian calendar, 2024 has not disappointed discerning horologists. This year, we've seen some standout pieces worthy of attention, including an award-winning creation from the GPHG. Here’s a closer look at the most remarkable calendar watches of 2024, featuring everything from a unique planetarium watch to a groundbreaking perpetual calendar.

Audemars Piguet Royal Oak Perpetual Calendar John Mayer

The Audemars Piguet Royal Oak Perpetual Calendar designed in collaboration with John Mayer is undoubtedly a highlight of this year’s calendar watch lineup. Its striking design, featuring a modern take on the classic Tuscan dial with a "Crystal Sky" texture reminiscent of crystallized metal, is simply stunning. Set within a luxurious 41mm white gold case, this timepiece maintains the hallmark displays expected from this emblematic model, including its distinctive week display at the dial's periphery.

More poignantly, this model marks the end of an era as it is the final variant to be powered by the self-winding perpetual calendar calibre 5134, a movement that has roots dating back to 1967. With the introduction of the new calibre 7121 in the updated Royal Oak Jumbo model, this watch stands as a touching farewell to the calibre 5134.

CVDK Grand Planetarium Eccentric

Renowned for its astronomical watches, Christiaan van der Klaauw has once again impressed with the Grand Planetarium Eccentric. This exceptional timepiece embodies the brand's commitment to mechanical innovation and astronomical accuracy. Featuring a mechanical planetarium that models all planets in our Solar System, the watch incorporates a sophisticated motion mechanic that presents each planet's path in an eccentric orbit, mirroring their real-life trajectories.

Notably, this watch showcases an impressive 3,338 teeth operating its complex system, demonstrating unparalleled craftsmanship. In addition, it offers calendar indications, zodiac signs, and time display, paired with a movement engineered in collaboration with UhrTeil AG.

IWC Portugieser Eternal Calendar

This year, IWC made waves with the Portugieser Eternal Calendar, their first-ever secular perpetual calendar designed to remain accurate without adjustment until the year 3999. This innovative timepiece is not only a technical feat but features a moon phase indicator that's accurate for an astonishing 45 million years.

The design reflects a meticulous understanding of calendar mechanics, capturing the nuances of centurial years, which are sometimes mistakenly noted as leap years. IWC has ingeniously crafted a gear system that seamlessly manages this 400-year calendar function with just eight components – a testament to Kurt Klaus' engineering brilliance, which has rightfully earned accolades at the GPHG 2024.

Laurent Ferrier Classic Moon Annual Calendar

Laurent Ferrier has raised the bar with the Classic Moon Annual Calendar, elegantly enhancing its earlier annual calendar watch by incorporating a moonphase display. This watch is a perfect representation of traditional haute horlogerie, characterized by its refined finishes and classic aesthetics.

The annual calendar is designed to require only one adjustment each year during February’s transition to March, elegantly balancing complexity with user-friendliness. Adding a moon complication created with aventurine glass and translucent blue enamel elevates the design further. While both the steel and gold options are visually stunning, the gold model with its opaline dial truly dazzles.

Patek Philippe In-Line Perpetual Calendar Salmon 5236P

Patek Philippe has once again showcased its legendary craftsmanship with the In-Line Perpetual Calendar 5236P. With its distinctive single-line calendar display featuring four non-overlapping discs for the day, date, and month, this watch delivers optimum functionality in a compact design.

The latest version, adorned with a salmon-toned dial set within a platinum case, exemplifies the brand’s commitment to creating timepieces that are both modern and traditionally elegant. The calibre 31-260 powering this watch not only underscores Patek Philippe’s meticulous attention to detail but also enhances its discreet complexity and sophistication.

Conclusion

2024 has proven to be an exceptional year for calendar watches, showcasing innovation, artistry, and impressive mechanical resilience. These notable timepieces not only represent functional elegance but also highlight the remarkable craftsmanship and technological advancements in watchmaking today.
