Seamaster Aqua Terra Shades Co-Axial Master Chronometer 34 mm - 220.53.34.20.10.001

Description

The Seamaster Aqua Terra is a superb tribute to OMEGA’s rich ocean heritage and combines classic design with contemporary inspiration.

This 34 mm model is crafted in polished 18K Moonshine™ Gold, with a conical crown and a wave-edged caseback with flat sapphire crystal.

The sun-brushed and lacquered dial is CVD-treated and presented in a lagoon green colour, featuring an applied circular date window in 18K Moonshine™ Gold, and silver coloured transfers. 18K Moonshine™ Gold has been used to coat the facetted hands, and to create the hour-markers, which are shaped like sailboat hulls and filled with white Super-LumiNova.

Set on a shimmering leather strap in pine green, this watch is powered by OMEGA’s Co-Axial Master Chronometer calibre 8801, certified at the industry’s highest standard by the Swiss Federal Institute of Metrology (METAS).

Master Chronometer Certified

Superior Precision

Twice as precise as any officially certified chronometer

Our Master Chronometer watches are tested and certified twice. First, the movement is Chronometer-certified according to international standard ISO3159, requiring a precision of -4/+6 second per day, following the tests at the Official Swiss Chronometer Control (COSC). Then, the watch head and its movement undergo eight Master Chronometer tests set by the Swiss Federal Institute of Metrology (METAS) with criteria of 0/+6 seconds per day.

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.

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

Moonshine^TM Gold
Sapphire Crystal

1 / 2

Moonshine^TM Gold

OMEGA created the exclusive Moonshine^TM Gold, an 18K yellow gold alloy, in 2019. Inspired by the shining moonlight in a dark blue sky, OMEGA's 18K Moonshine^TM Gold offers a distinctive paler hue than traditional 18K yellow gold and high resistance to the fading of colour and lustre over time. Its unique composition includes silver, copper and palladium for colour and stability.

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.
