Creator Consensus

Very positive

5 reviews: 5 positive, 0 mixed, 0 negative. 3 of 5 recommend it.

Every reviewer rates its functionality well, and most say it is startlingly light for its size without giving up robustness. Most also praise the titanium calibre as extreme engineering and the soft but secure elastic strap, and see the watch as a genuinely new design rather than a retro reissue. Some add that it wears smaller than its diameter and is priced below expectations for the technology.

Where they differ. The dial divides opinion: one reviewer likes its clean, date-free look, while another finds the skeletonised layout hard to read at a glance. One reviewer questions the security of the hook-and-loop closure that others praise, and one warns the case may overwhelm smaller wrists.

Video, 4 minHands-on reviewMay 2026

Positive

A features walkthrough of the Diver AIR, mostly reciting specs. The few opinions are positive: a precise bezel with no back play, an easy-to-use crown, good timegrapher accuracy, and a skeletonised look that delivers the promised airy effect.

Functionalitypositive: Praises the bezel's feel and notes it has no back play. 1:52
Finds the screw-down crown very easy to screw back in. 2:51

Notes the movement is more open than the standard Diver X Skeleton's. 3:20
Designpositive: Feels the see-through case convincingly looks like mostly air inside. 3:49

A Different Take on Hyper-Luxury Watchmaking | Hands-on: NEW Ulysse Nardin Diver Air

Video, 8 minHands-on reviewMay 2025

Very positive

Sees the Diver Air as one of the coolest sports watches from a technical standpoint. The reviewer praises its light, engineering-led construction, bezel action, movement and comfortable straps, and applauds the brand for trying new things. Acknowledges it won't suit everyone.

What they said, point by point

Wearabilitypositive: Short lug-to-lug makes the 44mm case wear more like a 42mm. 3:22
On a 6.2-inch wrist it is at the limit of what the reviewer can wear, but still workable. 3:51
Functionalitypositive: Considers it one of the coolest sports watches technically. 0:00
Bezel insert offers easy grip and a smooth turning action. 4:20
Movementpositive: Sees the ultralight titanium calibre as a showcase of extreme modern engineering. 4:20

Considers the straps perfect for a sports watch of this kind. 5:16
Originalitypositive: Appreciates a brand trying genuinely new things instead of reissuing back-catalogue models. 6:43
Notes the watch's look is dictated by its engineering rather than visual design. 3:51
Acknowledges the watch will not appeal to everyone. 7:13
Valuemixed: Raises the concern that 'recycled' can feel less premium when paying luxury prices. 6:14
Compared with: Tudor Pelagos: Used as a wearability reference; if you can wear it, this fits.
Rolex Deepsea Challenge: Traditional tough watches are thick and heavy; Diver Air challenges that.

Hands-On: Ulysse Nardin Diver [Air] Watch

ArticleHands-on reviewApr 2025Ripley Sellers

Very positiveRecommends, with caveats

Considers the Diver [Air] an impressive engineering feat whose extreme lightness creates a real tactile thrill without sacrificing shock or water resistance. Legibility suffers from the skeletonisation, but the $38,000 price is seen as surprisingly reasonable. It was one of the reviewer's favourite Watches & Wonders 2025 releases.

Disclosure: Hands-on at launch event

What the review says, point by point

Wearabilitypositive: Finds that the watch defies expectations when first picked up because it is so light.
Describes the weight being less than half what its size suggests as a tactile thrill.
Case & proportionsmixed: Notes that despite being a millimetre thinner than its sibling, it remains a large piece.
Functionalitypositive: Values that the light build makes no sacrifices in durability, shock and water resistance.
Dialmixed: Identifies at-a-glance legibility as the one area where the skeletonised watch falls short.
Suspects it may be most legible in the dark, when only the lume is visible.
Considers the legibility shortcoming easy to overlook given the lightness goal.
Bracelet & strappositive: Likes that both velcro ends let owners centre the closure under the wrist.
Values tool-free swapping without a proprietary system limiting third-party straps.
Valuepositive: Considers the price high but less than half of what was expected.
Sees making it a standard-production model rather than a limited halo piece as a sign of confidence.
Compared with: Richard Mille RM 27 Rafael Nadal: Similar ultra-light thrill, but the Diver [Air] costs a fraction of the price.
Casio G-Shock DW5600: Same weight, but a light resin G-Shock is expected; the Diver [Air] surprises.
Ulysse Nardin Diver X Skeleton: Looks similar but is a millimetre thinner and far lighter.

Very positiveRecommends

Enthusiastic about the Diver Air. The reviewer marvels that a 52 g watch withstands 200 m and 5,000 G, praises the titanium movement and its finishing, and sees it as a true watchmaking statement rather than just another diver.

The Incredibly Light Ulysse Nardin Diver (Air)

ArticleNewsApr 2025Rebecca Doulton

Positive

A launch article that mostly relays the brand's details on construction, materials and weight. The writer's own tone is mildly admiring, calling the watch an extreme push of the skeleton-diver concept and the power reserve impressive, but offers little first-hand evaluation.

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

Low-confidence reading: Announcement-style piece that largely restates brand information and specs; no evidence of handling and very few evaluative opinions.

What the review says, point by point

Movementpositive: Considers the 90-hour power reserve impressive, kept despite the drastically lightened barrel bridge.
Originalitypositive: Frames the watch as an envelope-pushing, extreme take on the skeleton diver idea.
Compared with: Ulysse Nardin Diver X Skeleton 44mm (2021): The earlier model weighed 105.8g; the Air weighs about half that.
