To achieve Master Chronometer status, it has passed the 8 rigorous tests set by METAS (The Swiss Federal Institute of Metrology).

STAINLESS STEEL

Stainless steel is certainly the most conventional of watchmaking materials for outer craftsmanship, and offers beauty, strength and affordability. OMEGA uses 316L stainless steel. Known for its corrosion-resistance and high lustre after polishing, this material is often the ideal choice for watches in both daily-use and high-stress situations such as diving and adventure.

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.

LIQUIDMETAL™

Since 2010, OMEGA has bonded its ceramics with an alloy called Liquidmetal™, which offers new decoration possibilities in a metal grey colour with superior scratch-resistance and enduring stability. Composed of titanium, zirconium and copper, this amorphous alloy is three times as hard as stainless steel. When bonded with ceramic parts, Liquidmetal™ can be offered in contrasting finishes (brushed or polished), thanks to the difference in hardness between the two materials.

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: 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.
