Aluminium
Aluminium offers the advantage of being a truly lightweight material used in decorative components. Through anodisation, it offers an extensive range of colours for creating stunning timepiece components, such as bezels, applied dial elements, and hands. In particular, OMEGA’s special anodisation process has enabled the creation of aluminium bezels that are almost twice as hard as conventional versions, making them significantly more resistant to external damage.
Sapphire Crystal
OMEGA uses synthetic sapphire crystal with scratch-resistant and anti-reflective treatments to enhance the fine details of its watches. Produced using the Verneuil process, which involves flame fusion with oxygen and hydrogen, the crystal achieves a rating of 9 on the Mohs hardness scale, making it virtually scratchproof and ensuring outstanding visibility.
Stainless Steel
316L stainless steel is OMEGA’s material of choice for watches, offering beauty, strength, and great value. Its high resistance to corrosion and polished lustre make it ideal for everyday wear as well as demanding environments, such as diving and adventures.
