Patek Philippe Cubitus History: From 2024 Launch to the 5840P

The Patek Philippe Cubitus is the square-cased sports watch that Patek Philippe introduced in October 2024, its first new collection in about 25 years according to A Blog to Watch. It arrived about three years after the steel Nautilus 5711 was discontinued, it shares the Nautilus's horizontally embossed dial and one-piece-middle case construction, and it has grown from three references in 2024 to six by April 2026, including the first Grand Complication in the line. This page follows that short history and says what we could and could not confirm. Prices and status notes were retrieved on October 30, 2026 and are indicative. We label claims CONFIRMED (two or more independent sources), REPORTED (one source), COMMUNITY (opinion or commentary) or UNCERTAIN (sources conflict or cannot be checked).

Why the Cubitus exists: the gap after the Nautilus 5711

The Cubitus is easiest to understand as an answer to a gap. Patek discontinued the steel Nautilus ref. 5711 in 2021 (Gear Patrol, A Blog to Watch). Gear Patrol, in a January 8, 2026 article, says Patek's CEO Thierry Stern wanted to stop the brand being known for one model, that the 5711 got farewell olive green and Tiffany Blue versions, and that the white gold 5811 which replaced it is not a steel watch. WorldTempus says production of the 5711 ceased in 2022, so the exact end date is UNCERTAIN, though 2021 is the date most sources use.

When the Cubitus appeared, A Blog to Watch noted that the Nautilus line had had no time-only stainless steel option since the 5711, and that the 5821/1A fills the slot at a lower price. Gear Patrol's 2026 piece lists the steel Nautilus models that remain as two annual calendars, a flyback chronograph and four ladies models. We found no Patek statement calling the Cubitus a successor; that framing is COMMUNITY commentary. Our reading is simply that Patek again has a steel, time-and-date sports watch, and it is not called Nautilus.

October 2024: three references and a $41,243 steel watch

SJX's review, published October 18, 2024, names three launch references and says none is a limited edition. The 5821/1A is steel with an olive-green dial; the 5821/1AR is steel with an 18k rose gold bezel and center links and a dark blue dial; the 5822P is platinum with a blue dial. All three are 45mm across the diagonal and 30m water resistant. The three-hand watches are 8.3mm thick and the platinum 5822P is 9.6mm, per SJX and A Blog to Watch.

The 5821 runs caliber 26-330 S C, an automatic with hours, minutes, seconds and date at 28,800 vph and a 45-hour reserve (SJX; A Blog to Watch gives 35 to 45 hours, a range). SJX adds that it is also used in the Calatrava and Nautilus, and that the rotor carries a stamped Cubitus motif echoing the dial. The 5822P uses caliber 240 PS CI J LU, a micro-rotor movement at 21,600 vph and 353 parts, with a large date, a combined day and moon-phase display and small seconds, and a baguette-cut diamond at six o'clock on the bezel that SJX calls a first for Patek.

US launch prices at press time, per A Blog to Watch, were $41,243 for the steel 5821/1A, $61,275 for the 5821/1AR and $88,378 for the 5822P. SJX gave Swiss prices of CHF 35,000, CHF 52,000 and CHF 75,000 before taxes, which we do not convert. All figures are REPORTED by one outlet each.

Nautilus DNA, square outline

Patek has not described the Cubitus as a Nautilus redo, but the sources keep describing the lineage. SJX says the case uses the Nautilus's one-piece middle, with the bezel held by lateral screws in the ears after the movement and dial go in from the front, and that Thierry Stern acknowledges the influence. A Blog to Watch calls the bevelled square bezel, angled ears and chamfered integrated lugs nearly unchanged from the Nautilus, and says the steel bracelet's rounded H-link is visually nearly identical. Gear Patrol says the Cubitus draws on the Nautilus, “some say too heavily.”

Where it differs is the outline. The Nautilus is a rounded octagon with ears; the Cubitus is a square with softened corners, which WorldTempus describes as measured diagonally and finished in a mix of satin and polished surfaces. Both carry a horizontal embossed dial, which SJX describes as a stamped motif similar to the Nautilus's. For the history of the shape that started it, see our Nautilus history and the Aquanaut history, and for the two existing sports lines side by side see Aquanaut vs Nautilus.

Gérald Genta designed the 1976 Nautilus. None of the Cubitus sources we read credits him with the Cubitus, and SJX and Gear Patrol do not mention him in this context, so we do not say he designed it.

2025: 40mm gold arrives

At Watches & Wonders Geneva 2025 Patek added two 40mm references, the 7128/1G in white gold with a blue-grey sunburst dial and the 7128/1R in rose gold with a brown horizontally embossed dial (Gear Patrol, April 7, 2025; updated April 8). Gear Patrol says they are the first precious-metal Cubitus models and the first all-gold ones, with no steel version, at 8.5mm thick, and sold only through authorized dealers. WorldTempus, in August 2025, confirms the spring 2025 debut and says the gold bracelets use a patented folding clasp. The movement is the 26-330 S C (listed as 26-330 S C/434), shared with the 45mm models, and the 7128/1G has an exhibition case back.

Gear Patrol put the price at $76,590 for each reference, taken from retailer links. This resolves a dating question: the 40mm references are a 2025 release, not a 2026 one. Luxury Bazaar's June 1, 2026 table lists both at $84,522 MSRP with a 2025 debut, which implies a price rise since launch. We did not find a Patek source for that increase; our 2026 price increases coverage describes the wider pattern. Treat $84,522 as REPORTED.

2026: the 5840P, the first Grand Complication

In April 2026 Patek showed the 5840P-001 Cubitus Perpetual Calendar Skeleton , which Luxury Bazaar and Esquire Singapore both call the first Grand Complication in the Cubitus line (CONFIRMED). It is a 45mm platinum case 10mm thick with a baguette-cut diamond at six o'clock, 30m water resistance and a sapphire caseback. The dial is fully skeletonised, and Esquire notes laser-cut shutter shades echoing the horizontal ribbing of the Nautilus and Cubitus dials.

The movement is caliber 28-28 Q SQU, an ultra-thin automatic that Luxury Bazaar says is 5.04mm thick with 313 components, a 38 to 48 hour reserve and a 22k gold off-centre micro-rotor at 21,600 vph. Esquire says it replaces the round caliber 240 Q and is shaped to fit the square case, with a blue hand-engraved Calatrava motif on the micro-rotor. It shows date, day, month, leap year and a single large moon for the phase. Our perpetual calendar history and Grand Complications history cover the wider tradition.

Luxury Bazaar gives a 2026 MSRP of $187,547; Esquire states no price, so the figure is REPORTED by one source. For other 2026 Patek news, see our Milan Grand Exhibition coverage and the Nautilus 50th anniversary report.

Is the steel Cubitus discontinued?

The status of the steel 5821/1A is the most confusing question around the watch, so here is the evidence. On October 30, 2026, text our fetch tool retrieved from Patek's own Cubitus collection page carried the notice “The models listed below are discontinued from our collection” above six references: 5821/1A-001, 5821/1AR-001, 5822P-001, 5840P-001, 7128/1G-001 and 7128/1R-001. We could not confirm how the live page renders, and the list includes the 5840P, which launched six months earlier, so we do not take this as a discontinuation of the whole line.

Other evidence points the other way. SRK Haute Horlogerie reports that on February 1, 2026 Patek tagged 20 references as discontinued and reversed the label by February 2, with no Cubitus on the list and no official statement. Luxury Bazaar's April 28, 2026 discontinued list says no Cubitus was discontinued, and the version we read on October 30 still says so. Dealer pages such as Wristaficionado and Avi & Co. were listing the steel 2026 5821/1A-001 when our search ran, although a dealer listing says nothing about Patek's catalog. Status: UNCERTAIN. We found no Patek announcement of a steel discontinuation, and we cannot rule out a website glitch like the one in February. Check with an authorized dealer.

Grey-market prices and what they mean

The one source with figures for every reference shows the watches trading far above retail. Luxury Bazaar's June 1, 2026 article lists 2026 market prices (undated within the year) against 2026 MSRP: the steel 5821/1A at $91,500 against $45,512, the steel and rose gold 5821/1AR at $100,000 against $68,643, the 5822P at $159,000 against $97,525, the 7128/1G at $125,000 against $84,522, the 7128/1R at $163,000 against $84,522 and the 5840P at $290,000 against $187,547. That works out to roughly twice retail for the steel watch, about 1.5 times for the 7128/1G and platinum 5840P and 1.9 times for the 7128/1R, our own arithmetic on one aggregator's figures, so REPORTED. The article says resale prices have risen slightly since launch.

Search results from European dealers showed asking prices of roughly EUR 87,000 to 91,000 for 2024 and 2025 steel examples; we have not converted these and could not open the listings or Chrono24 and WatchCharts to check, so they are UNCERTAIN. An asking price is not a sale price.

Patek Philippe Cubitus references and indicative US prices

How to buy a Cubitus: retail, grey market and caution

Retail. Gear Patrol says the 40mm references are sold only through authorized dealers, and SJX says the launch references were not limited editions. We found no public waitlist data, so we cannot say how long a retail allocation takes. Our secondary market report shows how scarcity plays out across the market.

Grey market. At the figures above, a pre-owned steel 5821/1A costs about $46,000 more than the 2026 retail price. Whether that premium lasts is the open question: Gear Patrol notes that 5711 secondhand prices climbed to multiples of retail during the waitlist era, but nothing guarantees the same for a different model. We found no evidence that any Cubitus will hold its premium, and in Luxury Bazaar's table the 40mm rose gold watch carries a bigger percentage premium than the steel.

Check before you pay. Confirm the reference and year against the papers and a dealer's written condition and return terms, and treat any listing far below the table with caution. If the square Patek is out of reach, the Nautilus and Royal Oak comparison and our Royal Oak history cover the other end of the integrated-bracelet world.

Myths and mix-ups, corrected

• “The Cubitus is a Nautilus.” It borrows a great deal: SJX and A Blog to Watch both describe the case and bracelet construction as close to the Nautilus. But it has its own name, a square outline and its own references.
• “Gérald Genta designed the Cubitus.” Genta designed the 1976 Nautilus. None of the Cubitus sources we read credits him with the Cubitus.
• “The Cubitus is the official replacement for the Nautilus 5711.” Patek has not said so in anything we found. A Blog to Watch notes it fills the time-only steel slot the 5711 left, but the successor framing is commentary.
• “The 40mm gold Cubitus launched in 2026.” Gear Patrol dates the 7128/1G and 7128/1R to Watches & Wonders 2025, and WorldTempus says spring 2025. The 2026 release was the 5840P.
• “Patek has discontinued the steel Cubitus.” UNCERTAIN. A Patek page notice, as our fetch returned it, lists all six references as discontinued, which includes a 2026 release. Luxury Bazaar says no Cubitus was discontinued, and Patek reversed a similar tagging in February 2026.
