The year 2025 has been a showcase for exceptional calendar timepieces, with manufacturers pushing the boundaries of mechanical ingenuity and aesthetic design. This curated selection spotlights six notable models that have left a lasting impression, encompassing a spectrum of complexities and styles. From highly sophisticated perpetual calendars that masterfully account for leap years, to innovative annual calendars prioritizing readability, and even a unique mechanical planner, these watches offer a blend of traditional craftsmanship and contemporary innovation. They represent the diverse and dynamic landscape of high-end watchmaking, providing enthusiasts with a rich variety of options to consider.
Audemars Piguet, a brand with a deep heritage in perpetual calendars, introduced the Royal Oak Perpetual Calendar featuring its groundbreaking Calibre 7138. This movement, a successor to the Calibre 5134, simplifies user interaction by integrating all adjustments through a single, patented crown, thus enhancing water resistance and ease of use. Housed within a 41mm case that is only 9.5mm thick, the watch also boasts an increased water resistance of 50m. The design, particularly the sand gold edition, is a striking example of modern horological excellence, merging the iconic Royal Oak aesthetic with advanced mechanical solutions. This release celebrates Audemars Piguet's 150th anniversary, underscoring its commitment to innovation and its rich legacy in complex watchmaking.
Independent watchmaker Sylvain Berneron presented the Quantième Annuel, an annual calendar watch that redefines legibility with its distinctive symmetrical 'double regulator' display. Unlike conventional annual calendars, this timepiece organizes its indications vertically and horizontally for maximum clarity. The jumping hours are prominently displayed in a large window at noon, flanked by central minutes and a small seconds sub-dial. Calendar information, including jumping days and months, is presented in rectangular apertures, with a retrograde pointer date. Encased in a compact 38mm platinum and steel body, the watch features a manually wound movement with a 100-hour power reserve, capable of managing four jumping indications while requiring only one annual correction on February 28th. Its elegant design and exceptional functionality make it a standout piece.
Chopard's L.U.C Lunar One perpetual calendar received a significant update for 2025, twenty years after its initial release. This timepiece is celebrated for its precise orbital moon phase display. The new edition comes in a more compact 40.5mm 18k ethical white or rose gold case, featuring a more readable dial and a convenient quick-release strap system. Key calendar functions, including a large date display and sub-dials for day and month, are thoughtfully arranged. The moon phase, situated within the small seconds sub-dial, boasts an impressive accuracy, requiring adjustment only once every 122 years. Powered by the chronometer-certified L.U.C 96.13L micro-rotor calibre, with two mainspring barrels providing a 65-hour power reserve, the watch exemplifies both mechanical prowess and refined aesthetics, further distinguished by the Poinçon de Genève hallmark.
Frederique Constant maintained its reputation for 'affordable luxury' with the reintroduction of its Classic Perpetual Calendar Manufacture. Originally launched in 2016 at a competitive price, the 2025 version arrives in a more svelte 40mm polished steel case. It is powered by the brand's 34th in-house movement, the Calibre FC-766, which now offers an extended 72-hour power reserve. The watch features a captivating sunray-brushed, salmon-colored dial with elegant applied indices and clearly arranged calendar indications. This model reinforces Frederique Constant's commitment to delivering sophisticated complications at an accessible price point, making high-end watchmaking more attainable for a broader audience.
Krayon, an independent brand led by Rémi Maillat, introduced the Anyday, a watch described as a 'mechanical agenda' that conceals considerable complexity beneath a deceptively simple exterior. This 39mm white gold timepiece features a conventional central hour and minute display, alongside a perimeter date scale indicated by a crescent-shaped pointer. Its true innovation lies in its ability to show the day of the week for any given date, with weekdays in navy blue and weekends transparent. While appearing straightforward, the underlying mechanics are highly intricate, allowing owners to easily plan their schedules. The Anyday represents a novel approach to calendar complications, offering a never-before-seen functionality that captivates and impresses with its clever design.
Roger Dubuis delved into its archives to reintroduce the Hommage La Placide Perpetual Calendar, a piece that pays homage to the brand's origins and the late Roger Dubuis's inventive spirit. Moving beyond its current 'hyper horology' image, this timepiece revives a bi-retrograde perpetual calendar module originally developed by Roger Dubuis and Jean-Marc Wiederrecht. The watch features restrained proportions, measuring 38mm by 11mm, echoing the classic dress watches from the brand's early Hommage collection. Its dial is a deep blue lacquered canvas, accented with mother-of-pearl counters and an aventurine moon phase display with yellow gold moons. This limited edition of 28 pieces combines the RD72 perpetual calendar module from 1999 with the in-house automatic RD14 calibre, offering collectors a rare glimpse into the brand's foundational artistry and meticulous craftsmanship.
This year's array of calendar watches, from Audemars Piguet's technological leap to Berneron's innovative legibility, Chopard's refined lunar display, Frederique Constant's accessible luxury, Krayon's unique planning functionality, and Roger Dubuis's historical tribute, highlights the enduring appeal and continuous evolution of horological artistry. These timepieces not only serve practical functions but also stand as testament to the boundless creativity and mechanical mastery within the watchmaking industry.
