  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.

Our 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.

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.

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 the water we have chosen – yet again - to exceed normal testing standards.

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.

A selection of test watches faces 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.
