Description

This classic yet robust timepiece represents a tribute to OMEGA’s rich maritime heritage. The dramatic and easily-recognisable dial design of the OMEGA Seamaster Aqua Terra 150M collection recalls the wooden decks of luxury sailboats.

This model features a sun-brushed and lacquered grey dial decorated with the Teak Concept pattern and a date window at 3 o'clock. A scratch-resistant sapphire crystal protects this unique dial.

The 18K red gold 41.5 mm case is presented on a brown leather strap. This certified chronometer is powered by the OMEGA Master Co-Axial calibre 8501 which is resistant to magnetic fields greater than 15,000 gauss and can be seen through the transparent caseback.

The advantages
of this watch

A key component of this timepiece is the Co-Axial escapement, which is able to maintain accuracy over a longer period of time. What’s more, all parts affecting accuracy are produced with non-ferromagnetic materials, ensuring the watch is protected from the strong magnetic fields produced by everyday items.

Superior Precision

Our Master Co-Axial Chronometer movements benefit from the Co-Axial escapement, which is able to maintain accuracy over a longer period of time. All parts affecting accuracy are also produced with non-ferromagnetic materials, ensuring that that precision will not be affected by magnetism (up to 15'000 gauss). Each movement is Chronometer-certified according to international standard ISO3159, requiring a precision of 0/+5 second per day, following the tests at the Official Swiss Chronometer Control (COSC).

Anti-magnetic

Proprietary anti-magnetic materials

Everyday items such as mobile phones, metal clasps on handbags, laptops, MRI, induction hobs or automatic doors; subject a watch to magnetic fields and can affect its performance. To prevent the risk of permanent deviations of up to several minutes a day we've conceived movements with antimagnetic materials, such as the silicon balance spring, capable of withstanding the highest fields.

Water-Resistance

To ensure the integrity of our timepieces at depth, not just some but all watches are fully immersed in water and pressure is applied up to the point of the guaranteed water resistance. By submerging each watch in water we have chosen – yet again - to exceed normal testing standards.

5-Year Warranty

In our quest to raise industry standards and push the boundaries of quality, all OMEGA watches are offered with a full 5-year warranty. This customer promise shows the confidence we have in the excellence of our timepieces, and provides extra trust and assurance when choosing your watch.

Less Servicing

Expect fewer visits to the service centre. The Co-Axial escapement is designed to reduce friction inside the movement. As a result, less lubrication is needed and hence less servicing. Compared to non-Co-Axial watches, the intervals between getting your watch serviced will be much longer.
6 / 6

Shock-resistance

During the homologation process, OMEGA watches are tested to the extreme. This phase includes shock examinations, to confirm reliability and to check that its precision is maintained after a severe impact. All OMEGA timepieces are designed to withstand shocks corresponding to a 1-metre drop on a hard wooden floor. For a standard 150g timepiece, this sudden and rapid acceleration is an equivalent force of up to 5,000 G on the watch head.

Key materials

Red Gold
Sapphire Crystal

1 / 2

Red 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 golds (with at least 75% pure gold) provides the ultimate balance between purity and usefulness. Traditional 18K red gold is alloyed with copper-silver 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.

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.

A new look for your watch

Your watch and strap should go together perfectly, but that doesn't mean you can't experiment with different combinations. Why not mix things up and see what happens? You may discover a look that's as individual as you are.
