Description

The ladies' Seamaster Aqua Terra is the true definition of elegance. Its ocean spirit can be seen throughout the design, while the finest materials and movements have been used in creation.

In this model, the symmetrical 38 mm case and integrated bracelet are crafted from stainless steel. The waved blue dial features a date window at 6 o’clock, while 18K Sedna™ gold is used for the hands as well as the indexes, which are shaped like sailboat hulls.

The watch is driven by the OMEGA Master Chronometer Calibre 8800, certified at the industry’s highest standard by the Swiss Federal Institute of Metrology (METAS).

5-Year Warranty

All OMEGA watches are delivered with a 5-year warranty that covers the repair of any material or manufacturing defects. Please refer to the operating instructions for specific information about the warranty conditions and restrictions.

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.

01 / 06

Twice as precise as any officially certified chronometer

Master Chronometer Certified

Our Master Chronometer watches are tested and certified twice. Firstly, the movement is tested by the Official Swiss Chronometer Control (COSC) with precision criteria of -4/+6 seconds per day. Then the complete watch and its movement undergo eight Master Chronometer tests set by the Swiss Federal Institute of Metrology (METAS) with criteria of 0/+5 seconds per day.

Proprietary anti-magnetic materials

Master Chronometer Certified

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 for good. 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

Master Chronometer Certified

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.

Durability

Master Chronometer Certified

Our watches are engineered to the highest standards and certified as such. Each watch destined to become a Master Chronometer must first pass 8 stringent tests. The examinations we perform for precision, magnetic-resistance, power reserve and water-resistance allow us to cover the certified watches with a comprehensive 5-year warranty.

Extended service intervals

Each Master Chronometer is equipped with a Co-Axial escapement, conceived to reduce the mechanical constraints inside the movement. This significantly reduces the need for lubrication and hence the need for servicing. All mechanical movements need to be serviced periodically, but an OMEGA Master Chronometer offers more time between servicing than many other watches.

Shock-resistance

A selection of test watches face shock-resistance examinations that are equivalent to 5,000 g (1 g is equal to the force of gravity at the Earth's surface) to ensure our complex mechanical mechanisms are also extraordinarily robust. Not just for everyday use but for active sports such as golf and sailing.

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.
