Crafted in steel, the Cubitus 5821-1A-001 measures 45mm (10 to 4 o'clock) with a slim 8.3mm height. The case is finished with a screw-down crown, a sapphire crystal case back, and water resistance to 30 metres, bringing together a refined architecture in a contemporary square-influenced form.
Powering the watch is the self-winding mechanical Caliber 26-330 S C, offering a date display via aperture and sweep seconds. The sunburst olive green dial is horizontally embossed and set with white gold applied hour markers bearing a white luminescent coating, lending the piece both visual depth and low-light legibility.
The steel bracelet is secured by a patented fold-over clasp featuring a lockable adjustment system, ensuring a precise and comfortable fit on the wrist. Reference 5821-1A-001 stands as a distinctive entry in the Cubitus collection, uniting Patek Philippe's horological craft with a modern aesthetic sensibility.
