Description

Built for sporting comfort, the ergonomically designed "Ultra Light" is fashioned from an alloy called Gamma Titanium, a strong yet lightweight material used in the aeronautical industry. The use of Gamma Titanium is a first for OMEGA. As is the telescopic crown, which can be stowed inside the case when not in use.

Presented on a black rubber strap, the watch includes a sandblasted grade 5 titanium dial featuring the iconic Aqua Terra stripes. When worn on the additional sporty fabric strap, the watch weighs just 55 grams.

This 41 mm Aqua Terra makes bold use of blue on the aluminium seconds hand, Seamaster logo, quarter hour markers and strap stitching. The watch is powered by the OMEGA Co-Axial Master Chronometer Calibre 8928 Ti, the brand's first movement built from titanium.

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.

Key materials

  • Material - Grade 5 Titanium

    Grade 5 Titanium

  • Material - Sapphire Crystal

    Sapphire Crystal

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.
