In our universe, the Earth’s oceans are naturally linked to the moon in our sky. For OMEGA, the connection can also be found in our latest ceramic collection. From the Speedmaster Dark Side of the Moon that  was first released in 2013,  OMEGA has evolved  its ceramic expertise to produce the Seamaster Planet Ocean “Deep Black”. This time, the craftsmanship has gone much further.
These four remarkable 45.5 mm timepieces are the combination of a GMT model and a diving watch. The true technical challenge was to produce a diving watch made entirely from ceramic and ensure that it could withstand the pressures of the ocean at a depth of 600  m / 2000  ft. / 60 bar.  However, the goal  has been achieved, and the result is a state-of-the-art creation that stands alone in the industry
10 Unique features of the
“Deep Black” Collection.
1 In a first for the  Planet  Ocean, the  case  body  of each “Deep Black” model has been crafted  from a single block of ceramic. The same material is also used for the unidirectional bezels as well as the dials that feature new Arabic numeral
2 On the Black and 18K Sedna™ gold models, the ceramic cases and dials have been polished for a glossy effect. The blue and red versions are brushed for a matt effect that offers better visibility underwater.
3 A new GMT ring has been  fixed on the dial while the diving scale sits on the ceramic bezel using Liquidmetal® or OMEGA Ceragold™.
4 For the  first time, rubber has been blended with ceramic to create a unique bezel. On the blue and red models, this colourful innovation can be seen covering the first 15 minutes.
5 For the Black model, Liquidmetal® is also used to create the He symbol on the Helium valve and OMEGA symbol on the crown. On the blue and red models, these two features are coloured using a rubber injection.
6 In another remarkable first, OMEGA has created an oriented caseback so that the engraved wording sits perfectly in position. This has been achieved through OMEGA’s new and patented ceramic Naiad Lock. The alveol design of the caseback also offers an aesthetic wave pattern.
7 Why the colours? Imagine you are descending below the waves of the ocean. At
5m, the first colour that is no longer visible is red. That means that this “military” divers’ watch will gain  a camouflage advantage by gradually matching  your wetsuit. Go deeper to 275 m and the last colour you’ll see, based on light penetration, is the exact shade of blue found on the blue Deep Black model. Finally, at a depth of 300 m, the ocean will turn black. The 18K Sedna™ gold model is a lifestyle piece built for people who enjoy time on deck.
8 The black rubber straps have been designed to give the appearance of being fabric. They feature contrasting stitching and have also been treated with an antibacterial coating. A wave pattern can be found on the underside.  On the Sedna™ gold model, the strap is water resistant leather, with the  same  anti-bacterial rubber  underside.  The foldover clasp is made from ceramised titanium, while the clasp cover has been produced in ceramic with two types of finishing.
9 The hands and indexes of the watches are created from
18K Sedna™ gold or 18K white gold. They are coated in
white Super-LumiNova that emits green and blue colours
10 The “Deep Black” is driven by the OMEGA Master Chronometer calibre 8906. Resistant to magnetic fields of 15,000 gauss, each watch has passed the 8 tests set by the Swiss Federal  Institute of Metrology  (METAS). This higher standard of precision  and performance is in addition to  traditional COSC  certification. The watch comes with a four year warranty.
