Cubitus

The Cubitus is the first new collection Patek Philippe launched in 25 years, unveiled in Munich on October 17, 2024. Before it, the last ground-up line was the ladies' Twenty~4 in 1999. So when Patek rolls out a squared-off, integrated-bracelet sports watch and calls it the fourth pillar of the house alongside the Calatrava, the Nautilus, and the Aquanaut, collectors pay attention. We sell and buy Patek at Ultimate Diamond on 47th Street, and the Cubitus is the most argued-about release we have handled since the last Nautilus discontinuations. The design is a rounded square: a 45mm case with a horizontally embossed dial, applied baton markers, a date at 3, and a bracelet that flows out of the case with no visible lugs. Thierry Stern, Patek's president, has said publicly the name comes from the cube shape and the sporty character. Retail on the steel launch model, reference 5821/1A-001, is CHF 35,000, roughly $40,000 to $43,000 depending on the day's exchange. The secondary market told a different story out of the gate, which is exactly the kind of gap we watch closely when a client wants to buy smart or sell into strength. If you want a straight read on where a specific reference trades this week, bring it to the counter or call us.

Collector's Lore

The Cubitus launch is already a case study in how the modern watch world reacts to a new Patek. The teaser landed October 13, 2024, and the full reveal came October 17 in Munich, breaking from Patek's usual Watches and Wonders Geneva rhythm. The reaction split the community immediately, with one camp calling it a bold new form and another calling it a Nautilus that got squared off, and that debate ran across every major watch outlet for weeks. There is a nice historical echo here. The Nautilus itself was not an instant hit in 1976; it was expensive steel that puzzled buyers and only became a legend decades later. Collectors who remember that arc are watching the Cubitus with that lesson in mind, which is why some are willing to sit on early premiums and others are convinced the square case will not age the way the porthole did. Thierry Stern staked real reputation on it by calling it a fourth collection rather than a limited experiment, and the addition of the 40mm gold 7128 within a year showed Patek was willing to adjust the recipe fast in response to the size complaints. For a house that lets time anoint its icons, deliberately building one and defending it in public is the story collectors will be retelling for years.
