Omega just made watchmaking history. Again.
The watchmaker has created the world’s first two-hand Master Chronometer. It’s officially one of the most precise watches ever certified—and it doesn’t have a seconds hand.
Omega has been setting precision standards its whole life, but this is an impressive feat, even for them.
Because if the seconds hand has always been the visual proof of accuracy, how can you possibly remove it entirely and still enhance precision? Let’s explore.
A close-up with the Omega Constellation Observatory
The Constellation name has been synonymous with precision since its debut in 1952, quickly becoming one of Omega’s most celebrated collections.
For the 2026 iteration, a minimalist design pulls from the brand’s dress watch heritage. An elegant aesthetic feels both timeless and modern, keeping signature design elements—like the “Pie-Pan” dial, dog-leg lugs and kite-form indexes—front and centre.
Across nine 39.4mm references, from steel to gold and platinum-gold, Omega has indulged in variation in the dial, treating us to traditional hand-finished executions and more technical takes, all in one drop.
Regardless of configuration, you can always be sure of the following when you buy a Constellation Observatory: it’ll be clean, precise, and executed to perfection. With a certification no two-hand watch has ever held.
The traditional role of the seconds hand
For centuries, the seconds hand has been a tool to measure precision in watchmaking. Its smooth sweep shows what’s happening under the hood. And, as every watch aficionado knows, the smoother the sweep, the more stable the movement.
Watchmakers have always relied on photographic tracking methods to capture the position of the seconds hand at set intervals throughout the day. This was the long-accepted gold standard method for assessing a watch’s timekeeping capabilities.
That was until now, when Omega asked, what happens if you remove the visual element altogether?
In answering that question, the watchmaker has left the seconds hand obsolete and redefined traditional accuracy testing.
How did Omega achieve such precision?
Incredible levels of precision without the seconds hand comes down to listening to time, instead of looking at it.
Here’s how the Omega Constellation Observatory achieved its certification.
01
Two new movements
Powering the Constellation Observatory are two newly developed Coaxial Master Chronometer calibres.
Calibre 8914 is at the heart of stainless steel models, while 8915 is reserved for the precious metal editions.
Both movements offer around 60 hours of power reserve and are built on Omega’s anti-magnetic architecture, ensuring stability in real-world conditions.
02
Acoustic precision testing
Instead of photography, accuracy is calibrated using sound.
Acoustic testing isn’t new to the industry, but Omega has pushed its capabilities at the Laboratoire de Précision in Switzerland, a certification body for precision measurement in watchmaking.
By continuously capturing the acoustic signature of the movement, the system can detect even the smallest blips in performance to know exactly when and why variations exist. No seconds hand required.
03
Continuous testing replaces regular checks
Traditional testing methods capture regular data points throughout the day, providing snapshots of a watch’s behaviour.
With just one release, Omega has made that system look almost archaic. It uses continuous monitoring across a 25-day period to account for every second. This creates a constant stream of data offering insights into how movements behave over time—not just in isolated moments.
At the Laboratoire de Précision, there’s no room for human error.
04
Testing in the real world
A watch’s performance in a laboratory doesn’t always translate to the real world.
So Omega made sure to track how factors like temperature, atmospheric pressure and magnetic fields affect timekeeping, in real-time.
05
COSC and METAS set the standard
The only way for a watch to achieve a Master Chronometer certification is to pass COSC and METAS testing.
COSC, a Swiss body that certifies the accuracy of Swiss watches, tested the movement using traditional (photographic) technology that measures the position of the hands at regular intervals throughout the day. COSC subjects timepieces to testing in different positions and temperatures to certify utmost precision.
The METAS method is even more stringent. It goes beyond movement to test the entire watch—case and all— in real-world conditions, when it’s up against magnetism, temperature fluctuations, and water. The Laboratoire de Précision tracks these external factors; Grand Master Chronometer status depends on results from the lab.
Own a world-first
The Constellation Observatory reminds us that even the most established traditions in watchmaking can be challenged.
The world’s first two-hand Master Chronometer will ground conversations in this industry for decades. Starting at £9,100 for the O-MEGASTEEL version, this 2026 Omega is worth acting on.
