OMEGA is proud to include the Swiss Made mark on all of its watches. This simple wording guarantees a standard of quality established over many centuries and is a world-renowned symbol of excellence.
As part of an exquisite collection of timepieces, this watch combines the iconic Constellation design with a dazzling selection of 634 precious stones totalling 1.56 ct.
The 29 mm case is crafted from 18K Canopus Gold™ and is snow-paved with 108 full cut diamonds. Gripping to its sides are the legendary polished claws, along with a bezel that features Roman numerals in positive relief and 160 full cut diamonds.
The astonishing attention to detail is continued on the 18K white gold dial, which is fully paved in a snow setting of 354 single cut diamonds. There is also an 18K white gold Constellation star, and most beautifully, a circle of 12 baguette-cut blue sapphire hour markers in 18K white gold holders. The hands are in PVD Canopus Gold™.
The watch is completed by a blue leather strap on a polished 18K Canopus Gold™ buckle. Behind the sapphire crystal on the caseback sits the OMEGA Co-Axial Master Chronometer Calibre 8703.
Anti-magnetic
The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
Chronometer
Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).
Diamonds
The hardest, most luminous precious stone whose value is calculated according to the 4C criteria: Cut - Carat - Clarity - Color.
Master Chronometer Certified
Guaranteeing the Swiss industry’s highest standard of precision, performance and magnetic-resistance, as set by the Swiss Federal Institute of Metrology (METAS).
Transparent caseback
A transparent caseback - frequently made of sapphire - makes it possible to see the movement inside the watch.

1 / 3
Canopus GoldTM
OMEGA has been using the exclusive Canopus GoldTM, an 18K white gold alloy, since 2015. As well as being 100% noble, it bears all the standard characteristics of other 18K golds, while also distinguishing itself for its high brilliance, whiteness and longevity, making it an ideal material for high-end or diamond set timepieces. The alloy is named after the bright star Canopus, which is 71 times bigger and 10’000 times brighter than our sun. Due to its brilliance and position, Canopus became an important reference point for many space agencies. Its unique composition includes platinum, rhodium and palladium for colour and stability.

Diamonds
Diamond is recognised as the hardest material on Earth, graded 10 on the Mohs hardness scale, and is the only gem made entirely of carbon. In nature, it can only be formed under high temperature and pressure conditions that exist within a specific depth range (~100 miles) beneath the Earth's surface. To decorate its timepieces and jewellery, OMEGA uses "Top Wesselton" white COLOUR diamonds with CLARITY ranging from pure to VVS (Very Very Small inclusions). Along with choosing the best weight in CARAT, the CUT is also carefully selected in order to maximise brightness and scintillation. It goes without saying that OMEGA is a certified member of the non-profit Responsible Jewellery Council (RJC), assuring customers that its processes involving people, materials and the environment are ethical and fair.

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.

The advantages of this watch
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.
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 -5/+8 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/+7 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. 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 water we have chosen – yet again - to exceed normal testing standards.
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.
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.
