Sorry, but this watch is no longer available.
This unique 39.5 mm Limited Edition model is limited to 88 pieces and has been created with an 18K white gold case that includes baguette diamonds on the bezel along with gradient blue sapphires over the first 15 minutes and an orange sapphire set at 12 o'clock.
The white mother-of-pearl dial features 18K white gold indexes filled with Super-LumiNova. Other elements include Arabic numerals and a date window at 3 o’clock as well as 18K white gold hands. The minute hand is also set with a single orange sapphire. The caseback includes a hand-engraved Seahorse set with diamonds.
Presented on an integreated white leather strap with rubber lining, it is water resistant to 600 metres / 2000 feet / 60 bar, is powered by the OMEGA Master Chronometer calibre 8801 and features revolutionary anti-magnetic technology.
The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).
The day of the month, displayed in a window on a watch dial at the 3 or 6 o’clock position, or within a subdial at 9 o'clock.
The hardest, most luminous precious stone whose value is calculated according to the 4C criteria: Cut - Carat - Clarity - Color.
Decompression system which allows helium to escape from inside the watch when the watch is worn for professional use in pressure chambers. (Long-term underwater work, crude oil exploration, etc.)
A series of watches whose production run is determined in advance of production and limited to a set number.
Guaranteeing the Swiss industry’s highest standard of precision, performance and magnetic-resistance, as set by the Swiss Federal Institute of Metrology (METAS).
Self-locking crown, screwed into the tube of the case, used for highly water resistant divers' watches.
A transparent caseback - frequently made of sapphire - makes it possible to see the movement inside the watch.
A bezel which turns in only one direction. Particularly useful for divers who cannot accidentally rotate it in the wrong direction, which could cause them to miscalculate their dive times. A rotating bezel makes it easy to measure elapsed time.
This measures the space where a strap or bracelet would be placed.
This is the full length of the case, from the top lugs to the bottom lugs.
This is the full width of the watch’s case, excluding the crown and pushers.
When viewed from the side, this measures from the base of the watch to the surface of the glass.

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

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.

Also known as "nacre", mother-of-pearl is an organic-inorganic composite material produced by some molluscs as an inner shell layer, similar to pearls. It is strong, resilient and iridescent, with changing colours depending on the wavelengths of light at different viewing angles. Produced with exquisite skill and delicacy, OMEGA's ladies' collection offers mother-of-pearl dials of top quality, enhanced with specific attributes.

Since 2010, OMEGA has bonded its ceramics with an alloy called LiquidmetalTM, which offers new decoration possibilities in a metal grey colour with superior scratch-resistance and enduring stability. Composed of titanium, zirconium and copper, this amorphous alloy is three times as hard as stainless steel. When bonded with ceramic parts, LiquidmetalTM can be offered in contrasting finishes (brushed or polished), thanks to the difference in hardness between the two materials.

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.

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.

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
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.
Master Chronometer Certified
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.
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.
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.
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.
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.
