Creator Consensus

Mixed

6 reviews: 3 positive, 2 mixed, 1 negative. 3 of 6 recommend it.

Reviewers are spread across the scale on this one.

Most reviewers praise how thin the case is for its size, and most rate its wearability and finishing positively. Most also feel it borrows too heavily from the Nautilus, and several consider it steep for an entry-level Patek. The dial draws more criticism than praise.

Where they differ. Several reviewers see a distinct new model built on Nautilus roots and find the design grows on them, while a couple think it feels unfinished. Opinion also splits on the bracelet, which several find supple but a couple feel is mismatched with the case.

Patek Philippe Cubitus 45mm (5821/1A-001)

Video, 12 minHands-on reviewDec 2025

Positive

Finds the 45mm Cubitus far more wearable than its size suggests thanks to its square shape, thinness and light weight, and praises dial and craftsmanship. Criticises the wide bracelet, Nautilus-like design and a steep retail price increase.

Suits: Wrists around 6.75–7 inches, though workable on smaller wrists

What they said, point by point

Case & proportionspositive: Finds the central case section of about 38mm reasonable rather than gigantic. 1:23
Considers the 44.1mm lug-to-lug not big at all. 1:52
Measured the case thinner than published and feels this reduces bulk. 9:15
Bracelet & strapmixed: Sees the 52.6mm bracelet width at the second link as a real problem of integrated designs. 2:21
Finds the signature bracelet very comfortable. 4:44
Judges the clasp adequate and solid, though not as sturdy as AP's. 5:42
Dialmixed: Admires the olive green sunburst dial. 3:16
Describes the dial layout as simple and elegant. 3:43
Feels the date window looks rather small, possibly due to lighting. 3:43
Originalitymixed: Finds the dial design very similar to the Nautilus, explaining public confusion. 3:16
Acknowledges there are enough differences despite the Nautilus resemblance from a distance. 0:28
Questions the purpose of the side case 'winglets', wondering if they are purely decorative. 4:15
Wearabilitypositive: Finds it surprisingly light for its size. 7:22
Notes the square shape keeps it from looking gigantic on the wrist. 7:50
Observes the case corners hug the wrist without sticking up. 8:46
Considers it workable on a 16.5cm wrist and no problem on larger wrists. 9:15
Finishing & buildpositive: Praises the bracelet's polished centre links and finishing. 4:44
Expresses being impressed by the brand's craftsmanship. 9:43
Valuenegative: Condemns the roughly $8,700 price increase in under a year. 10:41
Feels pricing is getting out of control for non-wealthy buyers. 10:41
Notes a large secondary-market premium, though pieces sit unsold for a long time. 11:36
Compared with: Rolex Oyster Perpetual 36: Cubitus lug-to-lug only slightly longer than the OP36's, so not big.
Rolex Land-Dweller: Land-Dweller bracelet drops vertically rather than flaring wide like the Cubitus.
Patek Philippe Nautilus: Dial design very similar; smaller secondary premium than steel Nautilus.
Patek Philippe Cubitus 40mm: Expects the 40mm to be a great size and more popular.

The Patek Philippe Cubitus: Hands-on impressions

Video, 5 minHands-on reviewNov 2024

Mixed

The reviewer is ambivalent, neither liking nor hating it. They praise the dial, thinness and the brave decision not to simply upsize the Nautilus. They find the rugged case clashes with the elegant bracelet, and call it a good idea poorly executed.

Patek Philippe Cubitus HANDS ON

Video, 11 minHands-on reviewNov 2024

MixedRecommends, with caveats

After handling the Cubitus, the reviewer mildly likes it but doesn't love it. The design feels derivative and unfinished, with off proportions, an overly spacious dial and a too-narrow bracelet. The price seems steep, and the watch suits larger wrists.

Suits: Wrists of 7 inches and up comfortable with large watches

Disclosure: Retailer stock

What they said, point by point

Wearabilitymixed: Finds the watch quite large on the wrist. 0:30
On a 5.5in wrist it looks oversized, but in an appealing way. 0:30

Believes the steel model should be priced nearer £25,000. 4:52
Doesn't think the watches justify their prices. 4:52
Compared with: Patek Philippe Aquanaut: Cubitus costs about 15,000 more than the Aquanaut, which is seen as entry-level.

The Steel Patek Philippe Cubitus 5821A on the Wrist

ArticleHands-on reviewOct 2024Brice Goulard

PositiveRecommends, with caveats

Finds the steel Cubitus far better in the metal than its online reputation: superb quality, excellent comfort, and wearable proportions close to the Nautilus. Wishes for more design differentiation from the Nautilus, a quick-change bracelet, and a shaped movement with longer power reserve.

What the review says, point by point

Designmixed: Considers the overall result much more attractive than online reactions imply.
Acknowledges the design is polarizing and far from consensual.
Would have preferred a bolder design with more distinct touches.
Originalitymixed: Sees a blend of familiar and new elements giving a distinct character.
Suggests a different dial pattern and colour to separate it from the Nautilus.
Feels the Nautilus resemblance invites unavoidable comparison.
Case & proportionspositive: Notes most real dimensions match the Nautilus; the diagonal figure is misleading.
Refuses to call it a big watch.
Considers it thin enough to rival the best in the category.
Wearabilitypositive: Rates comfort as top-tier.
Finds it wears nicely on average wrists and feels light.
Square shape gives it more visual presence than a Nautilus.
Bracelet & strappositive: Finds the bracelet thin, supple and soft to the touch.
Values the clasp's comfort extension for warm days.
Misses a quick-change system for swapping to straps, limiting versatility.
Movementnegative: Would have liked a square-shaped calibre to fully embrace the concept.
Considers the power reserve a downside of this movement.
Functionalitypositive: Expects it to handle swimming and shallow diving, beyond the stated rating.
Finishing & buildpositive: Judges build quality superb and fully Patek-worthy.
Compared with: Patek Philippe Nautilus 5711A: Near-identical thickness, lug-to-lug and width; Cubitus has more presence.
Patek Philippe Nautilus 5811G: Similar dimensions and comparable thinness.
Cartier Santos de Cartier Large: Cubitus is much smaller on many levels.
Audemars Piguet Royal Oak 16202ST: Cubitus thin enough to compete with it.

HANDS-ON with the new PATEK PHILIPPE CUBITUS Collection! (and four alternative square watches)

Video, 10 minHands-on reviewOct 2024

Negative

After trying the Cubitus range, the reviewer prefers the platinum model and does not love the steel version's green shade. The 45mm square case felt jarring on the wrist, and the design reads as a Nautilus derivative, though the collection may grow on people over time.

What they said, point by point

Dialnegative: Does not love the shade of green on the steel model, calling it purely personal preference. 4:44
Case & proportionsmixed: Highlights the case as notably thin at 8.3mm. 1:25
Finds the 45mm square case jarring when worn. 5:14
Wearabilitynegative: Compares the on-wrist feel to a Dick Tracy cartoon watch. 5:14
Says it felt like wearing an old box TV on the wrist. 5:42
Originalitymixed: Views the design as a Nautilus hybrid, melted down and reshaped with side wings. 6:10
Suggests the Nautilus resemblance may be what is putting people off. 6:10
Thinks the collection could come to be loved over time, as the Aquanaut did. 5:42
Compared with: Patek Philippe Nautilus: Sees the Cubitus as a reshaped hybrid of the Nautilus.
Patek Philippe Aquanaut: The Aquanaut was also jarring at launch but became loved; the Cubitus may follow.
Cartier Santos Large: Suggested as the most obvious, far cheaper square alternative.
Herbelin Cap Camarat Square Automatic: Thinks it looks closest to the Cubitus, at a fraction of the price.

Review: Patek Philippe Cubitus Ref. 5821 and Ref. 5822P

ArticleHands-on reviewOct 2024JX Su

PositiveRecommends, with caveats

The reviewer likes the Cubitus, especially the steel base model, and praises its cohesive design, thinness, supple bracelet and excellent external execution. The main weakness is the high price for a so-called entry model.

What the review says, point by point

Designpositive: Considers the Cubitus a successful new creation despite an odd-seeming recipe.
Likes how the large square bezel works with the case's side ears.
Feels the bracelet integrates surprisingly well into the overall design.
Originalitypositive: Notes the watch plainly inherits design traits from the Nautilus.
Finds the Nautilus-derived result more natural than the angular bezel implies.
Case & proportionspositive: Finds the case impressively thin for its size.
Says the 8.3mm case feels even thinner because of its wide diameter.
Wearabilitypositive: Considers the ergonomics good.
Finds it wears slightly slimmer on the wrist than Nautilus models.
Bracelet & strappositive: Finds the bracelet smooth and supple, improving comfort.
Feels the rounded, supple links give the bracelet model an elegant feel.
Finishing & buildpositive: Rates the external components as excellent and highly detailed.
Describes the movement finishing as industrial-grade high watchmaking.
Considers the steel reference very well executed.
Appreciates the collection-specific rotor decoration as a modest but unique touch.
Valuenegative: Sees price, not any tangible flaw, as the Cubitus's weakness.
Finds CHF35,000 a steep threshold for a supposed entry-level Patek.
Compared with: Patek Philippe Nautilus 5711: Cubitus wears a little slimmer on the wrist than the Nautilus.
Patek Philippe Cubitus 5822P: Platinum 5822P with new calibre is arguably the better value of the three.

Patek Philippe Cubitus Review | Here's why it's a major homerun!

Video, 5 minReactionOct 2024

PositiveRecommends, with caveats

Sees the Cubitus as a smart, low-risk extension of the Nautilus formula. The angular design and shared bracelet are strengths. It is priced like a steel Nautilus and may not command an early premium, and it does not replace the Nautilus.

Not a review of the watch in hand (news, a guide or a reaction), so it isn't counted.

What they said, point by point

Bracelet & strappositive: Calls the reuse of the Nautilus bracelet a blessing in disguise. 2:26
Rates the shared Nautilus bracelet among the best for fit, finish and comfort. 2:26
Originalitymixed: Notes the watch is strikingly similar to the Nautilus, with only the case shape changed. 1:57
Defends reusing a proven formula, likening it to Rolex's shared styling across its models. 3:21
Designpositive: Appreciates the angular shape and its 1970s TV-case vibe. 3:51
Finishing & buildpositive: Describes the watch as carrying the finest workmanship available. 3:51
Valuemixed: Notes it retails at the former steel Nautilus price, so it is not a budget alternative. 3:51
Expects it will likely not fetch the premium the Nautilus did, at least initially. 3:51
Compared with: Patek Philippe Nautilus: Offers the Nautilus experience but doesn't replace it; you'd still want one.
