Black ceramic on Rubber strap
Complimentary OMEGA watch care kit included.
Exploring the dark side of the ocean, OMEGA has evolved its ceramic expertise to produce the Seamaster Planet Ocean “Deep Black”. This remarkable 45.5 mm timepiece is the combination of a GMT model and a diving watch. It is coloured totally black to represent the ocean at a depth of 300 m. The glossy and brushed casebody has been crafted from a single block of ceramic, the same material used for the unidirectional bezel and the dial with Arabic numerals.
A new GMT ring has also been fixed on the dial while the diving scale and OMEGA logo on the crown have been decorated with Liquidmetal™. The hands are 18K white gold and are coated in white Super-LumiNova. In another first, OMEGA has created an oriented screw-in caseback so that the engraved wording sits pleasingly in position. This has been achieved through OMEGA’s new and patented ceramic Naiad Lock.
Other features include an alveol pattern on the screw-in caseback and a black rubber strap with contrasting stitching and an anti-bacterial treatment on the lining. The Planet Ocean “Deep Black” is water-resistant to 60 bar and is driven by the OMEGA Master Chronometer calibre 8906. To achieve Master Chronometer status, it has passed the 8 rigorous tests set by METAS (The Swiss Federal Institute of Metrology).
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.
GMT and Worldtimer
A watch with an additional 24-hour hand or 24-hour disc. Particularly useful for wearers who wish to track the hours in two time zones.
Helium escape valve
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.)
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).
Self-locking crown, screwed into the tube of the case, used for highly water resistant divers' watches.
Time zone function
Allows the hour hand to be easily adjusted to different time zones without stopping the watch.
Transparent case back
A transparent case back - frequently made of sapphire - makes it possible to see the movement inside the watch.
Unidirectional rotating bezel
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.
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.

OMEGA has unrivalled expertise in the use of ceramics, dating back more than 10 years. Taking its origin from the Greek word "keramos", ceramic is an inorganic, non-metallic substance obtained by firing at high temperatures. It allows the creation of completely dense watch parts with exceptional mechanical properties. Ceramic is one of the most popular choices for customers when selecting their timepiece, thanks to its appealing colour range and specific properties, such as it being two times lighter than stainless steel, hardwearing, highly scratch-resistant, chemically inert, hypoallergenic, environmentally friendly and non-magnetic.

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.

Master Chronometer Certified
Twice as precise as any officially certified chronometer
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 0/+5 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 %3/%4 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 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.

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.
4 / 6
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.

During the homologation process, OMEGA watches are tested to the extreme. This phase includes shock examinations, to confirm the reliability of each timepiece, 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.
Self-winding movement with Co-Axial escapement. Certified Master Chronometer, approved by METAS, resistant to magnetic fields reaching 15,000 gauss. GMT and time zone functions. Free sprung-balance with silicon balance spring, two barrels mounted in series, automatic winding in both directions. Special luxury finish with rhodium-plated rotor and bridges with Geneva waves in arabesque.
