Attention to details

The Diver 300M embodies OMEGA’s diving heritage. Water-resistant up to 300 meters it’s made for precision and durability. Each model features refined details like a domed sapphire crystal and a unidirectional bezel, adding timelessness to its adventurous spirit.

Material Matters

The Diver 300M series features OMEGA-developed alloys chosen for their durability and distinctive appearance, setting the Diver 300M apart with materials built to last.

Bronze Gold

Bronze Gold was specifically developed to produce a pleasing aesthetic and hue, while also offering a bronze alloy that could be worn with direct contact on the skin, thanks to its distinctive composition. This one-of-a-kind alloy is enriched with noble elements such as 37.5% gold, hallmarked as 9K, as well as palladium and silver, to create a unique colour which sits exactly between the brand’s 18K MoonshineTM gold and 18K SednaTM gold. As well as featuring a soft pink hue, during wear it offers incomparable corrosion resistance without verdigris-oxidation, and will therefore age slowly and retain its natural and beautiful patina over a longer period of time. For fans of bronze watches and innovative materials, this is great news!

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.

Aluminium

Aluminium has the advantage of being a truly lightweight material used for decorative components. Through anodisation, it offers an extensive range of colours for the creation of eye-catching watch parts such as bezel rings, applied elements on the dial, and hands. In particular, OMEGA’s special anodisation process has achieved aluminium bezel rings that are nearly double as hard as regular versions, therefore making them more resistant to outer damage.

Grade 5 Titanium

Titanium alloys are light, corrosion-resistant, biochemically inert and able to withstand extreme temperatures. These properties make them particularly appropriate for products in the aircraft, spacecraft and medical sectors. They achieve the perfect balance between solidity, corrosion-resistance and workability. Grade 5 titanium offers a bright grey colour that is close to that of stainless steel, and suits both "brushed" and "polished" finishing.

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.
