Patek Philippe’s Calatrava Collection: A Timeless Classic
One of the most iconic collections from Patek Philippe, the Calatrava, has been a cornerstone for the brand since its debut in 1932.
This collection’s sleek and minimalist design was first motivated by the Bauhaus movement, which focused on practicality and geometric forms. Functionality, naturally, is a crucial element for watchmakers, and they proudly offer mechanical movements that ensure remarkable accuracy.
Throughout its nearly 90-year journey, the Calatrava collection has evolved to include various complications and style choices. These have ranged from diamond-set editions to perpetual calendars and minute repeaters. This year, a hand-wound movement has been introduced as an “everyday complication” in the latest Reference 5328G, the brand notes.
This new watch features the 31-505 8J PS IRM CI movement, which can run for a full eight days when fully wound. This impressive power allows the day of the week display—located at 6 o’clock—to advance precisely when the date on the subdial shifts to the next number. At midnight, both the date and the day of the week update in perfect harmony through their individual mechanisms.
This instantaneous movement is made feasible partly due to the advanced technological innovations developed under the Patek Philippe Advanced Research Program. The lever and escape wheel are crafted from the brand’s special Cylinbar, a lightweight and non-magnetic silicone-based material that also withstands temperature fluctuations. Two barrels provide enough energy for that remarkable eight-day power reserve, and the watch’s transparent sapphire case back lets admirers fully appreciate the intricately finished movement.
The watch also features a power reserve indicator positioned at 12 o’clock, similar to a vehicle’s fuel gauge. The hands on this indicator gradually move along its arc, alerting the wearer when the power is running low by entering a red zone. This signals that the watch needs winding as it approaches its ninth day of operation.
But the movement isn’t the watch’s only highlight. The 18K white gold case displays Calatrava’s signature clous de Paris—or “hobnail”—pattern on the side, a departure from the usual placement on the bezel.
The blue dial is elegantly textured, drawing inspiration from vintage camera cases and gradually shifting to a darker tone near the edges, turning almost black. Fans of the brand may recognize this texture from the Reference 5226G-001 Calatrava launched in 2022.
Adding to its adaptability, the watch is equipped with two quick-change straps. One is crafted from navy blue calfskin with a fabric pattern and cream stitching, while the other is made of taupe grain calfskin. Patek Philippe’s new patented triple-blade fallover clasp ensures effortless swapping between straps without any tools required.
The 18K white gold clasp proudly displays the Calatrava cross emblem, a trademark since 1887. Although the cross bears a resemblance to the fleur-de-lis found in the French royal family’s coat of arms, the exact origins of this symbol remain unclear.
“It’s quite possible that this symbol of prestige and sovereignty influenced the choice of the lily motif, which represents the company’s commitment to excellence,” the brand suggests.
