Main materials
To truly appreciate every detail of a watch, OMEGA uses synthetic sapphire crystal with a highly scratch-resistant and anti-reflective coating. Before machining and finishing, sapphire crystals are produced using the Verneuil process, also called flame fusion. This involves melting the raw material using an oxygen/hydrogen flame and crystallizing the molten droplets to form a cylinder. With a grade 9 on the Mohs hardness scale (graded 1-10), the resulting sapphire crystals are virtually scratch-resistant and very hard, ensuring that vision is never impaired.
Since 2012, OMEGA has used its exclusive 18K Sedna™ gold, its own reddish-rose gold alloy. Named after Sedna—an orbiting planetoid that has been described as one of the reddest in the solar system—Sedna™ gold exhibits all the standard characteristics of other 18K golds—but also offers high resistance to fading of color and luster over time. Its unique composition includes copper and palladium for color and stability.

Twice as Precise as Any Officially Certified Chronometer
Our Master Chronometer watches are tested and certified twice. First, the movement is certified as a Chronometer under the ISO3159 standard by the Contrôle Officiel Suisse des Chronomètres (COSC). Then, the fully cased watch undergoes eight Master Chronometer tests set by the Swiss Federal Institute of Metrology (METAS), requiring precision of 0/+5 seconds per day.
Patented Antimagnetic Materials
Everyday objects such as mobile phones, magnetic clasps, laptops, MRI equipment, induction hobs or automatic doors expose watches to magnetic fields, which can disrupt their performance. To avoid permanent deviations of several minutes per day, we use antimagnetic materials like the silicon balance spring, capable of withstanding the strongest fields.
To guarantee integrity at depth, every OMEGA watch – not just some – is fully immersed in water and pressure-tested up to the guaranteed water resistance. By testing every watch, we go far beyond the usual industry standards.
In our pursuit to raise industry standards and push the limits of quality, all OMEGA watches are delivered with a full 5-year warranty. This commitment reflects the confidence we have in our timepieces, offering customers extra peace of mind.
Expect fewer visits to the service center. The Co-Axial escapement was designed to reduce mechanical limitations inside the movement, requiring less lubrication and therefore less servicing. Compared to non-Co-Axial watches, service intervals are significantly longer.
During certification, OMEGA watches undergo extreme testing, including shocks to ensure reliability and accuracy even after heavy impacts. Each watch is designed to resist shocks equivalent to a 1-meter fall onto solid wood, generating forces up to 5000G for a 150g watch.
