The Patek Philippe Cubitus (ref. 5821/1A-001) marks a noteworthy expansion of the brand’s design language—its first new collection since the Aquanaut. Bold in both scale and spirit, the watch is defined by a faceted stainless steel case measuring 45mm across, anchored by an integrated bracelet and a vibrant sunburst green dial that underscores its athletic poise.

Inside, the Cubitus is powered by calibre 26‑330 S C, a self-winding movement offering central seconds and a date function, along with a 35–45 hour power reserve. The steel bezel is finished with sharp angular accents that echo the case geometry, while luminous hour markers and hands ensure legibility. A screw-down crown and solid construction contribute to a water-resistance rating of 30 metres.

Launched in 2024, the 5821/1A-001 signals Patek Philippe’s willingness to push boundaries in case architecture and size, without compromising mechanical refinement. The Cubitus stands alone as a purposeful shift into contemporary sport-luxury territory, primed for collectors who favour modern dimensions and distinctive profiles under one of watchmaking’s most storied names.
