OMEGA Constellation Co-Axial Master Chronometer 41mm O13123412110001

The dramatic and enduring design of the OMEGA Constellation is characterised by its famous half-moon facets and “claws” on the case. This 41 mm model, in stainless steel and 18K Yellow gold, features a black polished ceramic bezel ring with Roman numerals filled with OMEGA Ceragold™. It has a sun-brushed green dial with gradient effect and a date window at the 6 o'clock position. The hands, OMEGA logo, Constellation star and indexes are also in 18K Yellow gold. Replacing the famous mono-rang bracelet is a green leather strap with rubber lining. At the heart of this timepiece is the OMEGA Co-Axial Master Chronometer Calibre 8900, visible through the scratch-resistant sapphire crystal.

YELLOW GOLD

Gold in its pure form (24K) is slightly reddish yellow and very soft. It is usually alloyed with other base metals for a diverse variety of uses. Considered to be the premium standard in watch and jewellery making, 18K golds (with at least 75% pure gold) provides the ultimate balance between purity and usefulness. Traditional 18K yellow gold is alloyed with copper-silver and offers an excellent resistance to corrosion, while being highly bio-chemically inert. It provides a beautiful hue that suits wearers even with sensitive skin.

CERAMIC

OMEGA has unrivalled expertise in the use of ceramics, dating back more than 10 years. Taking its origin from the Greek word "keramos", ceramic is an inorganic, non-metallic substance obtained by firing at high temperatures. It allows the creation of completely dense watch parts with exceptional mechanical properties. Ceramic is one of the most popular choices for customers when selecting their timepiece, thanks to its appealing colour range and specific properties, such as it being two times lighter than stainless steel, hardwearing, highly scratch-resistant, chemically inert, hypoallergenic, environmentally friendly and non-magnetic.

SAPPHIRE CRYSTAL

To really appreciate the finer details of a timepiece, OMEGA uses synthetic sapphire crystal with a highly scratch-resistant and anti-reflective treatment. Before the machining and finishing processes take place, the sapphire crystals are produced under the Verneuil process, also called flame fusion. It involves the melting of the raw substance using oxyhydrogen flame and the crystallisation of the melted droplets to form a cylinder. Graded 9 on the Mohs-hardness scale (graded 1-10), the resulting sapphire crystals are virtually scratch-proof and very hard, ensuring an unhindered vision at all times.

OMEGA CONSTELLATION MEN

OMEGA: Master Chronometer

Bringing together luxurious design and ground-breaking functionality, OMEGA have earned a reputation for producing world class timepieces that never fail to make a lasting impression.

In 1848, when Louis Brandt sat down to create the company’s very first watches, his ambition was to produce the most accurate movements possible. For OMEGA, precision is still the truest mark of mechanical watchmaking quality. For someone investing in a watch, those few extra seconds are a testament to superior craftsmanship, a determination for perfection, more technical investment, more research, more development and an infinite passion for achieving better innovation.

Since 2015, OMEGA’s Master Chronometer testing for each individual timepiece has provided customers with total transparency and a proven precision and performance they can trust.
