Cubitus

Perpetual Calendar. Skeleton.

Ref. 5840P-001

Unveiled at Watches & Wonders on April 14th, 2026, the Patek Philippe 5840P-001 introduces an entirely new design language—Cubitus. Moving away from traditional round or elliptical forms, its softly squared case delivers a bold yet balanced aesthetic, staying true to Patek Philippe’s refined proportions. Crafted in platinum with a striking blue sunburst dial, it embodies a modern, architectural presence. More than a new reference, it marks the beginning of an entirely new collection.
