OMEGA introduces a landmark advancement in horology with the unveiling of the Constellation Observatory Collection—the first two-hand watch ever to achieve Master Chronometer certification. This milestone signals a new era in precision testing, made possible through pioneering technology developed by the Laboratoire de Précision.

A New Standard in Precision

Traditionally, precision certification required the presence of a seconds hand to measure performance. Now, thanks to a newly developed acoustic testing method—certified by METAS—OMEGA has eliminated that limitation.

By combining acoustic analysis with optical hand-tracking, the Constellation Observatory undergoes both Chronometer and Master Chronometer testing without the need for a seconds display. The result is a quieter, more refined expression of timekeeping—without compromising accuracy.

“This breakthrough has allowed us to present the first two-hand watch to achieve Master Chronometer certification,” said Raynald Aeschlimann.

Inside the Laboratoire de Précision

At the core of this innovation is the Laboratoire de Précision, an independent certification body responsible for its own measurement systems and testing protocols. Accredited for both Chronometer and Master Chronometer standards, the laboratory ensures impartial, high-precision results that set a new industry benchmark.

Its proprietary Dual Metric Technology uses a wireless, self-contained unit to capture continuous acoustic data—tracking each tick in real time while simultaneously monitoring environmental variables such as temperature, magnetic fields, pressure, and position across a 25-day testing cycle.

Unlike traditional methods that recorded a single daily measurement, this approach delivers a constant stream of data, allowing watchmakers to identify not just deviations, but precisely when and where they occur.

Heritage Meets Innovation

The Constellation Observatory Collection builds on a legacy that dates back to 1952, reinterpreting signature design codes with contemporary engineering. The 39.4 mm timepieces feature the iconic pie-pan dial, Constellation star at 6 o’clock, and Observatory medallion caseback—hallmarks of the line’s identity.

Design elements such as dauphine hands, faceted indexes, and distinctive dog-leg lugs reference early Constellation models, while refined finishes and modern materials bring the collection firmly into the present.

New Movements, Elevated Craft

Powering the collection are two new Master Chronometer calibres—Calibre 8915 and Calibre 8914—each showcasing OMEGA’s technical and decorative expertise. From skeletonised rotors to intricate finishing and applied Observatory medallions, the movements reflect a balance of performance and artistry.

The collection is presented across three tiers—Grand Luxe, Luxe, and Standard—spanning precious metals and the brand’s proprietary O-MEGASTEEL alloy. Highlights include the use of 18K Moonshine™ Gold and Sedna™ Gold, alongside a platinum-gold edition that unites OMEGA’s full spectrum of exclusive alloys.

A Defining Moment for Watchmaking

With the Constellation Observatory Collection, OMEGA not only advances the technical boundaries of precision but also redefines what is possible in minimalist watch design. By removing the necessity of a seconds hand while enhancing accuracy, the brand offers a new perspective on time—one that is both quieter and more exacting.

In doing so, OMEGA reinforces its position at the forefront of innovation, where heritage craftsmanship meets the future of horology.
