About the Cubitus family
The Cubitus was launched in late 2024 as Patek Philippe's first new permanent collection in about 25 years. It takes the sporty, integrated-bracelet idea of the Nautilus into a squarer case with rounded corners, a horizontally embossed dial and alternating satin and polished finishes.
The first models were 45 mm: ref. 5821/1A in steel, ref. 5821/1AR in steel and rose gold, both with the automatic caliber 26-330 S C, and ref. 5822P in platinum with a grand date, moon phase and instantaneous day display. In 2025 Patek added smaller 40 mm models in white and rose gold, ref. 7128. As a recent line, Cubitus pieces trade mostly as near-new watches, so complete sets and protective stickers matter.
