A Peek At The Patek Philippe Cubitus Perpetual Calendar Skeleton

comments 3 Share The introduction of the distinctly different-shaped Cubitus collection in October 2024 didn’t go unnoticed. Patek Philippe stated that the Cubitus collection’s mission is “to offer a new reinterpretation of the ‘elegant, sporty’ style” through a design in which the square bezel adopts rounded corners, “blending the square, the circle, and the octagon.” When you look at the basic Cubitus models, the link to the mighty Nautilus is obvious. That’s also what fueled much of the skepticism regarding the design. That and the fact that the square case housed a round movement. The complicated Patek Philippe Cubitus Perpetual Calendar Skeleton Ref. 5840P-001, which debuted during Watches and Wonders 2026, might still have the same case shape, but the dial is no longer so Nautilus-like thanks to its open-worked “blinds.” And the new caliber 28-28 Q SQU is not round but shaped. Let’s peek through the blinds.
