Omega has introduced the Constellation Observatory, marking a milestone as the first two-hand watch to obtain Master Chronometer certification.
This achievement is made possible by a novel acoustic testing method developed by the independent Laboratoire de Précision, created in 2024, and certified by METAS.
It allows movements and complete watches to undergo both Chronometer and Master Chronometer testing without requiring a seconds hand.
The Constellation Observatory collection comprises nine new references. Five are crafted in precious metals — four in 18K gold and one in Platinum Gold — while four are in O-MEGASTEEL.
Since its debut in 1952, the Constellation has symbolised Omega’s commitment to certified accuracy.
The Constellation Observatory continues this tradition, employing a combination of acoustic tests and optical hand-tracking developed by the Laboratoire de Précision, which operates as an independent certification authority with its own measurement technology and governance.
Accredited by SAS (Swiss Accreditation Service) and certified by METAS, the laboratory provides impartial, confidential results for the entire watch industry.
The acoustic methodology is implemented in a wireless, autonomous testing unit based on Dual Metric Technology.
Unlike traditional methods that photographed the seconds hand to obtain one result per day, the new system records continuous acoustic data over a 25-day cycle.
Environmental factors such as temperature, position, magnetic fields, and atmospheric pressure are tracked simultaneously, enabling watchmakers to identify not only the presence of deviations but also precisely when and where they occur.
The Constellation Observatory is housed in a 39.4 mm polished‑brushed case with faceted ‘dog-leg’ lugs and a bezel featuring clear-cut facets. The case has a thickness of 12.23 mm.
It is fitted with a domed, bevelled, scratch‑resistant sapphire crystal treated with anti-reflective coating on both sides, and offers 3 bar (30 metres / 100 feet) water resistance.
The hallmark Constellation design features — the dodecagonal “pie‑pan” dial, the star emblem at 6 o’clock, and the Observatory medallion on the caseback — are all present.
Guilloché finishes, kite-shaped indices, and Dauphine hands evoke past Grand Luxe models, while the bracelet in nine-row Moonshine 18K gold recalls the classic “brick” pattern of early Constellations.
Two new movements power the collection.
The Calibre 8915 Grand Luxe, reserved for the Platinum Gold edition, features a rotor in 18K Sedna gold with spiral finish and a dark blue aventurine enamel Observatory medallion with eight stars.
The Calibre 8915 Luxe, designed for 18K gold models, introduces for the first time a rotor and balance bridge in Moonshine 18K gold alongside Sedna 18K, with “Côtes de Genève” arabesque decoration.
The Calibre 8914 Standard is a rhodium-finished variant of the 8915 Luxe, powering the O-MEGASTEEL references.
All calibres feature skeletonised rotors and bridges, medallions applied to the rotor in the respective metal, an operating frequency of 3.5 Hz, and a power reserve of 60 hours.
The five precious-metal references showcase four 18K gold editions (Sedna or Moonshine) and one Platinum Gold model.
Each combines case, hand-guilloché dial, and movement in matching metals, offered with either leather strap or matching bracelet.
The four O-MEGASTEEL references are selected for their mechanical robustness and feature black ceramic “pie-pan” dials or coloured dials with printed grooves.
Prices of the new Omega Constellation Observatory start at €10,800 / US$10,900. omegawatches.com
