Creator Consensus

Positive

6 reviews: 5 positive, 1 mixed, 0 negative. 3 of 6 recommend it.

Most reviewers welcome the return of dog-leg lugs and rate the movement highly, with several praising its acoustic chronometer testing and robustness. Several single out the pie-pan and black ceramic dials and the faceted, polished hands and markers. The main reservation, shared by most, is that the case is thick and large for a dress watch, and some find the pricing steep.

Where they differ. Some reviewers feel the absence of a seconds hand adds elegance, while one misses it. Some also find the pricing steep, whereas one feels the technical features justify it, particularly in steel.

This New Omega Surprised Me - Constellation Observatory

Video, 8 minHands-on reviewMay 2026

PositiveRecommends, with caveats

The reviewer finds the Observatory far better in person than in renders: classy, tough and beautifully finished, with a favourite Omega movement. The price is the major caveat, especially without a bracelet and compared with the Globemaster it replaces.

Pie Pan Perfection (or a swing and a miss)? The OMEGA Constellation Observatory. Full Review!

Video, 13 minHands-on reviewApr 2026

Mixed

Loves the pie-pan dial with its facets and dog-leg lugs, calling it near perfection. However, the reviewer finds the case too big for a dress watch, some dials hard to read, misses a seconds hand, and considers the prices excessive. Suggests a smaller Omega alternative.

Hands On: Omega Constellation Observatory

ArticleHands-on reviewMar 2026Brandon Moore

PositiveRecommends, with caveats

Sees the Observatory as a heritage-rich showcase of Omega's chronometry and materials, with superb hands and markers and fair steel pricing. The main drawback is a case over 12mm thick, inherited from the movement, though clever case design disguises it well.

Suits: Precision-minded enthusiasts, especially in the more accessible steel versions

What the review says, point by point

Case & proportionsmixed: Considers the thickness over 12mm chunky by dress watch standards.
Finds that the case looks and feels thinner than rivals with similar dimensions.

Notes the thickness becomes an issue with tight shirt cuffs.
Dialpositive: Praises the thick, triple-faceted hands for luxury finishing and legibility.
Notes that the domed crystal's distortion dulls the stamped guilloche pattern.
Finds the lighter steel variant with Sedna gold furniture less affected by this distortion.
Designpositive: Sees real elegance in the stately two-hand layout.
Supports Omega challenging the expectation that a chronometer needs a seconds hand.

Finds the absence of the Spirate adjustment system curious for a performance-oriented watch.
Movementpositive: Considers the calibre robust and technically impressive.
Views the calibre as both proven and technically advanced.
Would have preferred a slimmer movement.
Finishing & buildpositive: Calls the faceted, polished kite-shaped markers exemplary.
Notes that even the marker flanks are mirror-polished, giving an expensive look.
Finds the movement decoration machine-applied but distinctive and appealing.
Accepts selective movement decoration as an expected cost-saving concession.
Originalitypositive: Appreciates how the design discreetly nods to Omega's precision-timekeeping history.
Valuepositive: Considers the value reasonable, especially in steel.
Believes unique technical features justify the asking price.
Notes the steel Observatory costs about CHF2,000 less than the rival Grand Seiko.
Compared with: Grand Seiko SLGW005: Similar concept, but the steel Observatory is about CHF2,000 cheaper.

ArticleNewsMar 2026Xavier Markl

Positive

A launch article that mostly restates the collection's specs. The writer finds it compelling for reviving the 1950s pie-pan Constellation design and for making a two-hand watch the first Master Chronometer, a surprise that is ultimately judged a reasonable step.

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

What the review says, point by point

Case & proportionspositive: Notes that the box sapphire crystals keep the case band thin, helping the watch sit elegantly.
Welcomes the return of the distinctive dog-leg lug shape.
Originalitypositive: Frames it as a new family inspired by a historical model's aesthetics rather than an entirely new design.
Finds the launch compelling for pairing design continuity with a certification innovation.
Movementpositive: Found it surprising that an 'Observatory' chronometer omits a central seconds hand.
Argues it is reasonable that a two-hander's precision should be certifiable.
