Description

The Seamaster Aqua Terra is a superb tribute to OMEGA’s rich maritime heritage. This 41mm model has a symmetrical polished-brushed case in stainless steel and 18K Sedna™ gold, and a screw-in caseback with a wave-edged design.

The silvery sun-brushed dial has a horizontal “teak” pattern inspired by the wooden decks of luxury sailboats, which is a signature feature of these models. Keeping track of the hours, minutes and seconds are facetted hands in 18K Sedna™ gold, filled with white Super-LumiNova. Days are marked by a date window at 6 o'clock.

Matching perfectly with the case is a stainless steel and 18K Sedna™ gold bracelet. Powering the watch is OMEGA’s Master Chronometer calibre 8900 - certified at the industry’s highest level by the Swiss Federal Institute of Metrology (METAS).

SednaTM Gold

OMEGA has been using the exclusive 18K SednaTM Gold, its own fiery rose gold alloy, since 2012. Named after Sedna, an orbiting planetoid that has been described as one of the reddest in the solar system, SednaTM Gold not only bears all the standard characteristics of other 18K golds, but it also offers high resistance to the fading of colour and lustre over time. Its unique composition includes copper and palladium for colour and stability.

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.

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.
