Introduced in 2026, the Patek Philippe Cubitus 5840P-001 is the line's first Grand Complication, featuring a perpetual calendar within a 45 mm platinum case. The openworked sunburst blue dial includes a horizontal pattern, luminescent white gold indices, and various sub-dials for calendar functions and moon phases. It is powered by the square, skeletonized self-winding caliber 28-28 Q SQU, visible through the sapphire case back. The watch is secured by a navy blue composite strap with a platinum fold-over clasp.
