Omega Constellation Co-Axial Master Chronometer

Constellation with METAS-certified Co-Axial movement

The Constellation with Co-Axial Master Chronometer calibre combines the iconic design of the line with what is currently the strictest movement certification in the industry. The four claws on the bezel, the faceted case and the distinctive transition between case and bracelet remain characteristic. Inside are manufacture calibres with Co-Axial escapement and silicon balance spring, which withstand magnetic fields of up to 15,000 gauss and are tested by the Swiss federal institute METAS.

What Master Chronometer means

Master Chronometer certification goes well beyond the classic COSC test. It is not just the bare movement that is tested but the fully assembled watch – in eight tests over ten days, under the influence of magnetic fields, in different positions and at different temperatures. The tests cover rate accuracy, power reserve, water resistance and functionality under 15,000 gauss. Every certified watch receives an individual test report that can be retrieved using the case number.

The claws as a hallmark

The four claws on the bezel are more than mere decoration. They were introduced in 1982 with the Constellation Manhattan and originally served to press the sapphire crystal against the gasket, thereby improving water resistance. This engineering solution became the defining design feature of the line, making the Constellation instantly recognisable to this day.

Who the line is for

The Constellation Co-Axial Master Chronometer is aimed at wearers looking for an everyday watch without compromising on precision or craftsmanship. The models are available in several case sizes and in combinations of stainless steel, Sedna™ gold and yellow gold, and can be worn with a suit just as well as with casual attire.
