SEAMASTER DIVER 300
The Seamaster Diver 300M combines maritime heritage with modern design and innovation. This 42 mm model is crafted from Grade 2 titanium and Bronze Gold, featuring a green anodised aluminium bezel and a sandblasted green dial. It boasts Bronze Gold hands and hour markers filled with vintage Super-LumiNova. Presented on a brushed mesh bracelet, it is powered by the Co-Axial Master Chronometer Calibre 8806, visible through the sapphire crystal caseback with its wave-edged design.
Aluminium
Aluminium has the advantage of being a genuinely lightweight material used for decorative components. Through anodisation, it offers an extensive range of colours for creating stunning watch parts, such as bezels, dial-applied elements, and hands. In particular, OMEGA’s specialised anodising process has made it possible to create aluminium bezels that are nearly twice as hard as standard versions, making them significantly more resistant to external damage.
Sapphire Crystal
OMEGA uses synthetic sapphire crystal with scratch-resistant and anti-reflective treatments to showcase the fine details of its timepieces. Produced using the Verneuil process, which involves flame-fusion using an oxygen-hydrogen flame, the crystal achieves a hardness rating of 9 on the Mohs scale, rendering it virtually scratch-proof and ensuring outstanding visibility.
Stainless Steel
316L stainless steel is OMEGA’s material of choice for watchmaking, offering beauty, strength, and value. Its high corrosion resistance and high-gloss polish make it ideal for everyday wear as well as demanding environments such as diving and adventure.
