Omega 220.15.30.20.56.001 Seamaster Aqua Terra 150M Steel
The Seamaster Aqua Terra is a superb tribute to OMEGA’s rich maritime heritage. This slim 30 mm model achieves its refined proportions through OMEGA's innovative Co-Axial Master Chronometer calibre 8750, certified at the industry's highest standard by the Swiss Federal Institute of Metrology (METAS).
This stainless steel model has a symmetrical polished case and features a screw-in caseback with wave-edged design.
The grey dial is sun-brushed, PVD colour-treated and lacquered, with a circular date window at 6 o’clock. It is highlighted by 11 diamond hour markers and redesigned faceted hands, with the minute hand tapering to a delicate point. All the applied elements and hands are in 18K white gold, while the hands are also filled with white Super-LumiNova which emits a blue glow.
The watch is presented on an integrated stainless steel bracelet with beautifully rounded polished-brushed links, a foldover butterfly clasp, and OMEGA’s easy comfort-adjustment system.
White Gold
Gold in its pure form (24K) is slightly reddish yellow and very soft. It is usually alloyed with other base metals for a diverse variety of uses. Considered to be the premium standard in watch and jewellery making, 18K gold(with at least 75% pure gold) provides the ultimate balance between purity and usefulness. Traditional 18K white gold is alloyed with palladium-copper and offers an excellent resistance to corrosion, while being highly bio-chemically inert. It provides a beautiful hue that suits wearers even with sensitive skin.
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.
Diamonds
Diamond is recognised as the hardest material on Earth, graded 10 on the Mohs hardness scale, and is the only gem made entirely of carbon. In nature, it can only be formed under high temperature and pressure conditions that exist within a specific depth range (~100 miles) beneath the Earth's surface. To decorate its timepieces and jewellery, OMEGA uses "Top Wesselton" white COLOUR diamonds with CLARITY ranging from pure to VVS (Very Very Small inclusions). Along with choosing the best weight in CARAT, the CUT is also carefully selected in order to maximise brightness and scintillation. It goes without saying that OMEGA is a certified member of the non-profit Responsible Jewellery Council (RJC), assuring customers that its processes involving people, materials and the environment are ethical and fair.
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.
The advantages of this watch
Inside this timepiece are the revolutionary components that guarantee the highest standards of performance. From the Co-Axial escapement for long-lasting precision, to the silicon balance spring for superior anti-magnetism, OMEGA has conquered every challenge that matters.
